 ## TODO - contribute
 This project is far from being finished, and there are still a lot of things to do for this project to become a firmware usable by the general public.
 Here a quick list out of my head of things to do for this project:
 - Improve BLE communication stability and reliability
 - Improve OTA and MCUBoot bootloader
 - Add more functionalities : Alarm, chronometer, configuration, activities, heart rate logging, games,...
 - Add more BLE functionalities : call notifications, agenda, configuration, data logging,...
 - Measure power consumption and improve battery life
 - Improve documentation, take better pictures and video than mine
 - Improve the UI
 - Create companion app for multiple OSes (Linux, Android, iOS) and platforms (desktop, ARM, mobile). Do not forget the other devices from Pine64 like [the Pinephone](https://www.pine64.org/pinephone/) and the [Pinebook Pro](https://www.pine64.org/pinebook-pro/).
 - Design a simple CI (preferably self-hosted and easy to reproduce).
 Do not hesitate to clone/fork the code, hack it and create pull-requests. I'll do my best to review and merge them :)

 # BLE FS
 ---
 The BLE FS protocol in InfiniTime is mostly Adafruit's BLE file transfer protocol, as described in [adafruit/Adafruit_CircuitPython_BLE_File_Transfer](https://github.com/adafruit/Adafruit_CircuitPython_BLE_File_Transfer). There are some deviations, such as the status codes. These will be described later in the document.
 ---
 ## UUIDs
 There are two relevant UUIDs in this protocol: the version characteristic, and the raw transfer characteristic.
 ### Version
 UUID: `adaf0100-4669-6c65-5472-616e73666572`
 The version characteristic returns the version of the protocol to which the sender adheres. It returns a single unsigned 32-bit integer. The latest version at the time of writing this is 4. 
 ### Transfer
 UUID: `adaf0200-4669-6c65-5472-616e73666572`
 The transfer characteristic is responsible for all the data transfer between the client and the watch. It supports write and notify. Writing a packet on the characteristic results in a response via notify.
 ---
 ## Usage
 The separator for paths is `/`, and absolute paths must start with `/`.
 All of the following commands and responses are transferred via the transfer characteristic
 ### Read file
 To begin reading a file, a header must first be sent. The header packet should be formatted like so:
 - Command (single byte): `0x10`
 - 1 byte of padding
 - Unsigned 16-bit integer encoding the length of the file path.
 - Unsigned 32-bit integer encoding the location at which to start reading the first chunk.
 - Unsigned 32-bit integer encoding the amount of bytes to be read.
 - File path: UTF-8 encoded string that is _not_ null terminated.
 To continue reading the file after this initial packet, the following packet should be sent until all the data has been received. No close command is required after the data has been received.
 - Command (single byte): `0x12`
 - Status: `0x01`
 - 2 bytes of padding
 - Unsigned 32-bit integer encoding the location at which to start reading the next chunk.
 - Unsigned 32-bit integer encoding the amount of bytes to be read. This may be different from the size in the header.
 Both of these commands receive the following response:
 - Command (single byte): `0x11`
 - Status (signed 8-bit integer)
 - 2 bytes of padding
 - Unsigned 32-bit integer encoding the offset of this chunk
 - Unsigned 32-bit integer encoding the total size of the file
 - Unsigned 32-bit integer encoding the amount of data in the current chunk
 - Contents of the current chunk
 ### Write file
 To begin writing to a file, a header must first be sent. The header packet should be formatted like so:
 - Command (single byte): `0x20`
 - 1 byte of padding
 - Unsigned 16-bit integer encoding the length of the file path.
 - Unsigned 32-bit integer encoding the location at which to start writing to the file.
 - Unsigned 64-bit integer encoding the unix timestamp with nanosecond resolution. This will be used as the modification time. At the time of writing, this is not implemented in InfiniTime, but may be in the future.
 - Unsigned 32-bit integer encoding the size of the file that will be sent
 - File path: UTF-8 encoded string that is _not_ null terminated.
 To continue reading the file after this initial packet, the following packet should be sent until all the data has been sent and a response had been received with 0 free space. No close command is required after the data has been received.
 - Command (single byte): `0x22`
 - Status: `0x01`
 - 2 bytes of padding.
 - Unsigned 32-bit integer encoding the location at which to write the next chunk.
 - Unsigned 32-bit integer encoding the amount of bytes to be written.
 - Data
 Both of these commands receive the following response:
 - Command (single byte): `0x21`
 - Status (signed 8-bit integer)
 - 2 bytes of padding
 - Unsigned 32-bit integer encoding the current offset in the file
 - Unsigned 64-bit integer encoding the unix timestamp with nanosecond resolution. This will be used as the modification time. At the time of writing, this is not implemented in InfiniTime, but may be in the future.
 - Unsigned 32-bit integer encoding the amount of data the client can send until the file is full.
 ### Delete file
 - Command (single byte): `0x30`
 - 1 byte of padding
 - Unsigned 16-bit integer encoding the length of the file path.
 - File path: UTF-8 encoded string that is _not_ null terminated.
 The response to this packet will be as follows:
 - Command (single byte): `0x31`
 - Status (signed 8-bit integer)
 ### Make directory
 - Command (single byte): `0x40`
 - 1 byte of padding
 - Unsigned 16-bit integer encoding the length of the file path.
 - 4 bytes of padding
 - Unsigned 64-bit integer encoding the unix timestamp with nanosecond resolution.
 - File path: UTF-8 encoded string that is _not_ null terminated.
 The response to this packet will be as follows:
 - Command (single byte): `0x41`
 - Status (signed 8-bit integer)
 - 6 bytes of padding
 - Unsigned 64-bit integer encoding the unix timestamp with nanosecond resolution.
 ### List directory
 Paths returned by this command are relative to the path given in the request
 - Command (single byte): `0x50`
 - 1 byte of padding
 - Unsigned 16-bit integer encoding the length of the file path.
 - File path: UTF-8 encoded string that is _not_ null terminated.
 The response to this packet will be as follows. Responses will be sent until the final entry, which will have entry number ==  total entries
 - Command (single byte): `0x51`
 - Status (signed 8-bit integer)
 - Unsigned 16-bit integer encoding the length of the file path.
 - Unsigned 32-bit integer encoding the entry number
 - Unsigned 32-bit integer encoding the total amount of entries
 - Flags: unsigned 32-bit integer
 	+ Bit 0: Set when entry is a directory
 	+ Bits 1-7: Reserved
 - Unsigned 64-bit integer encoding the unix timestamp  of the modification time with nanosecond resolution
 - Unsigned 32-bit integer encoding the size of the file
 - Path: UTF-8 encoded string that is _not_ null terminated.
 ### Move file or directory
 - Command (single byte): `0x60`
 - 1 byte of padding
 - Unsigned 16-bit integer encoding the length of the old path
 - Unsigned 16-bit integer encoding the length of the new path
 - Old path: UTF-8 encoded string that is _not_ null terminated.
 - 1 byte of padding
 - Newpath: UTF-8 encoded string that is _not_ null terminated.
 The response to this packet will be as follows:
 - Command (single byte): `0x61`
 - Status (signed 8-bit integer)
 ---
 ## Deviations
 This section describes the differences between Adafruit's spec and InfiniTime's implementation.
 ### Status codes
 The status codes returned by InfiniTime are a signed 8-bit integer, rather than an unsigned one as described in the spec.
 InfiniTime uses LittleFS error codes rather than the ones described in the spec. Those codes can be found in [lfs.h](https://github.com/littlefs-project/littlefs/blob/master/lfs.h#L70).

 # How to flash InfiniTime using the SWD interface
 Download the files **bootloader.bin**, **image-x.y.z.bin** and **pinetime-graphics-x.y.z.bin** from the release page:
 ![Image file](imageFile.png)
 The bootloader reads a boot logo from the external SPI flash memory. The first step consists of flashing a tool in the MCU that will flash the boot logo into this SPI flash memory. This first step is optional but recommended (the bootloader will display garbage on screen for a few second if you don't do it).
 Using your SWD tool, flash **pinetime-graphics-x.y.z.bin** at offset **0x0000**. Reset the MCU and wait for a few seconds until the logo is completely drawn on the display.
 Then, using your SWD tool, flash these file at the following offsets:
 - bootloader.bin : **0x0000**
 - image-x.y.z.bin : **0x8000**
 Reset and voilà, you're running InfiniTime on your PineTime!

 ### Apps with multiple screens
 InfiniTime provides a mini-library in [displayapp/screens/ScreenList.h](/src/displayapp/screens/ScreenList.h)
 which makes it relatively  easy to add multiple screens to your app.
 To use it, #include it in the header file of your app and add a ScreenList member to your class.
 The template argument should be the number of screens you need.
 You will also need to add `CreateScreen` functions that return `std::unique_ptr<Screen>`
 to your class, one for every screen you have.

 # Coding convention
 ## Language
 The language of this project is **C++**, and all new code must be written in C++. (Modern) C++ provides a lot of useful tools and functionalities that are beneficial for embedded software development like `constexpr`, `template` and anything that provides zero-cost abstraction.
 C code is accepted if it comes from another library like FreeRTOS, NimBLE, LVGL or the NRF-SDK.
 ## Coding style
 The most important rule to follow is to try to keep the code as easy to read and maintain as possible.
 Using an autoformatter is highly recommended, but make sure it's configured properly.
 There are preconfigured autoformatter rules for:
  * CLion (IntelliJ) in [.idea/codeStyles/Project.xml](/.idea/codeStyles/Project.xml)
  * `clang-format`
 Also use `clang-tidy` to check the code for other issues.
 If there are no preconfigured rules for your IDE, you can use one of the existing ones to configure your IDE.
 - **Indentation** : 2 spaces, no tabulation
 - **Opening brace** at the end of the line
 - **Naming** : Choose self-describing variable name
    - **class** : PascalCase
    - **namespace** : PascalCase
    - **variable** : camelCase, **no** prefix/suffix ('_', 'm_',...) for class members
 - **Include guard** : `#pragma once` (no `#ifdef __MODULE__ / #define __MODULE__ / #endif`)
 - **Includes** :
    - files from the project : `#include "relative/path/to/the/file.h"`
    - external files and std : `#include <file.h>`
    - use includes relative to included directories like `src`, not relative to the current file. Don't do: `#include "../file.h"`
 - Only use [primary spellings for operators and tokens](https://en.cppreference.com/w/cpp/language/operator_alternative)
 - Use auto sparingly. Don't use auto for [fundamental/built-in types](https://en.cppreference.com/w/cpp/language/types) and [fixed width integer types](https://en.cppreference.com/w/cpp/types/integer), except when initializing with a cast to avoid duplicating the type name.
 - Examples:
   - `auto* app = static_cast<DisplayApp*>(instance);`
   - `auto number = static_cast<uint8_t>(variable);`
   - `uint8_t returnValue = MyFunction();`
 - Use nullptr instead of NULL

 # Coding convention
 ## Language
 The language of this project is **C++**, and all new code must be written in C++. (Modern) C++ provides a lot of useful tools and functionalities that are beneficial for embedded software development like `constexpr`, `template` and anything that provides zero-cost abstraction.
 C code is accepted if it comes from another library like FreeRTOS, NimBLE, LVGL or the NRF-SDK.
 ## Coding style
 The most important rule to follow is to try to keep the code as easy to read and maintain as possible.
 Using an autoformatter is highly recommended, but make sure it's configured properly.
 There are preconfigured autoformatter rules for:
  * CLion (IntelliJ) in .idea/codeStyles/Project.xml
 If there are no preconfigured rules for your IDE, you can use one of the existing ones to configure your IDE.
 - **Indentation** : 2 spaces, no tabulation
 - **Opening brace** at the end of the line
 - **Naming** : Choose self-describing variable name
    - **class** : PascalCase
    - **namespace** : PascalCase
    - **variable** : camelCase, **no** prefix/suffix ('_', 'm_',...) for class members
 - **Include guard** : `#pragma once` (no `#ifdef __MODULE__ / #define __MODULE__ / #endif`)
 - **Includes** :
    - files from the project : `#include "relative/path/to/the/file.h"`
    - external files and std : `#include <file.h>`
 - Only use [primary spellings for operators and tokens](https://en.cppreference.com/w/cpp/language/operator_alternative)
 - Use auto sparingly. Don't use auto for [fundamental/built-in types](https://en.cppreference.com/w/cpp/language/types) and [fixed width integer types](https://en.cppreference.com/w/cpp/types/integer), except when initializing with a cast to avoid duplicating the type name.
 - Examples:
   - `auto* app = static_cast<DisplayApp*>(instance);`
   - `auto number = static_cast<uint8_t>(variable);`
   - `uint8_t returnValue = MyFunction();`
 - Use nullptr instead of NULL

 # Firmware, InfiniTime, Bootloader, Recovery firmware, OTA, DFU... What is it?
 You may have already encountered these words by reading the announcement, release notes, or [the wiki guide](https://wiki.pine64.org/wiki/Upgrade_PineTime_to_InfiniTime_1.0.0) and you may find them confusing if you're not familiar with the project.
 A **firmware** is software running on the embedded hardware of a device.
 InfiniTime has three distinct firmwares:
 - **[InfiniTime](https://github.com/InfiniTimeOrg/InfiniTime)** is the operating system.
 - **[The bootloader](https://github.com/JF002/pinetime-mcuboot-bootloader)** is responsible for safely applying firmware updates and runs before booting into InfiniTime.
 - **The recovery firmware** is a special *application firmware* than can be loaded by the bootloader on user request. This firmware can be useful in case of serious issue, when the main application firmware cannot perform an OTA update correctly.
 **OTA** (**O**ver **T**he **A**ir) refers to updating of the firmware over BLE (**B**luetooth **L**ow **E**nergy). This is a functionality that allows the user to update the firmware on their device wirelessly.
 **DFU** (**D**evice **F**irmware **U**pdate) is the file format and protocol used to send the update of the firmware to the watch over-the-air. InfiniTime implements the (legacy) DFU protocol from Nordic Semiconductor (NRF).
 ## Bootloader
 Most of the time, the bootloader just runs without your intervention (updating and loading the firmware).
 However, you can use the bootloader to rollback to the previous firmware, or load the recovery firmware using the push button:
 - Press and hold the button until the pine cone is drawn in **blue** to force the rollback of the previous version of the firmware, even if you've already validated the current one.
 - Press and hold the button until the pine cone is drawn in **red** to load the recovery firmware. This recovery firmware only provides BLE connectivity and OTA functionality.
 More info about the bootloader in [its project page](https://github.com/JF002/pinetime-mcuboot-bootloader/blob/master/README.md).

-You might have already seen these words by reading the announcement, release notes, or [the wiki guide](https://wiki.pine64.org/wiki/Upgrade_PineTime_to_InfiniTime_1.0.0) and, you may find them misleading if you're not familiar with the project.
+## InfiniTime quick user guide
 Basically, a **firmware** is just a software running on the embedded hardware of a device, the PineTime in this case.
 **InfiniTime** is based on 3 distinct **firmwares**:
 - **[InfiniTime](https://github.com/InfiniTimeOrg/InfiniTime)** itself, this is the *application firmware* running on the PineTime. This is the main firmware which provides most of the functionalities you'll use on a daily basis : bluetooth low-energy (BLE) connectivity, applications, watchfaces,...
 - **[The bootloader](https://github.com/JF002/pinetime-mcuboot-bootloader)** is responsible for safely applying **updates** of the *application firmware*, reverting them in case of issues and load the recovery firmware when requested.
 - **The recovery firmware** is a specific *application firmware* than can be loaded by the bootloader on user request. This firmware can be useful in case of serious issue, when the main application firmware cannot perform an OTA update correctly. Currently, this  recovery firmware is based on [InfiniTime 0.14.1](https://github.com/InfiniTimeOrg/InfiniTime/releases/tag/0.14.1).
 **OTA** and **DFU** refer to the update of the firmware over BLE (**B**luetooth **L**ow **E**nergy). **OTA** means **O**ver **T**he **A**ir, this is a functionality that allows the user to update the firmware how their device using a wireless communication like BLE. When we talk about **DFU** (**D**evice **F**irmware **U**pdate), we refer to the file format and protocol used to send the update of the firmware to the watch over-the-air. InfiniTime implement the (legacy) DFU protocol from Nordic Semiconductor (NRF).
 ## How to check the version of InfiniTime and the bootloader?
 Since September 2020, all PineTimes (devkits or sealed) are flashed using the **[first iteration of the bootloader](https://github.com/lupyuen/pinetime-rust-mynewt/releases/tag/v4.1.7)** and **[InfiniTime 0.7.1](https://github.com/InfiniTimeOrg/InfiniTime/releases/tag/0.7.1)**. There was no recovery firmware at that time.
 The bootloader only runs when the watch starts (from an empty battery, for example) or after a reset (after a successful OTA or a manual reset - long push on the button).
 You can recognize this first iteration of the bootloader with it greenish **PINETIME** logo.
 ![Old bootloader logo](oldbootloaderlogo.jpg)
 You can check the version of InfiniTime by opening the app *SystemInfo*. For version < 1.0:
 ![InfiniTime 0.7.1 Application menu](appmenu-071.jpg)
 ![InfiniTime 0.7.1 version](version-071.jpg)
 And for version >= 1.0 :
 ![InfiniTime 1.0 version](version-1.0.jpg)
 PineTime shipped from June 2021 (to be confirmed) will be flashed with the [new version of the bootloader](https://github.com/JF002/pinetime-mcuboot-bootloader/releases/tag/1.0.0), the [recovery firmware](https://github.com/InfiniTimeOrg/InfiniTime/releases/tag/0.14.1) and [InfiniTime 1.0](https://github.com/InfiniTimeOrg/InfiniTime/releases/tag/1.0.0).
 The bootloader is easily recognizable with it white pine cone that is progressively drawn in green. It also displays its own version on the bottom (1.0.0 as of now).
 ![Bootloader 1.0](bootloader-1.0.jpg)
 ## How to update your PineTime?
 To update your PineTime, you can use one of the compatible companion applications. Here are the main ones:
 - **[Amazfish](https://github.com/piggz/harbour-amazfish)** (Desktop Linux, mobile Linux, SailfishOS, runs on the PinebookPro and the Pinephone)
 - **[Gadgetbridge](https://www.gadgetbridge.org/)** (Android)
 - **[Siglo](https://github.com/alexr4535/siglo)** (Linux, GTK based)
 - **NRFConnect** (closed source, Android & iOS).
 See [this page](ota-gadgetbridge-nrfconnect.md) for more info about the OTA procedure using Gadgetbridge and NRFConnect.
 ### From InfiniTime 0.7.1 / old bootloader
 If your PineTime is currently running InfiniTime 0.7.1 and the old bootloader, we strongly recommend you update them to more recent version (Bootloader 1.0.0 and InfiniTime 1.0.0 as of now). We also recommend you install the recovery firmware once the bootloader is up-do-date.
 Using the companion app of your choice, you'll need to apply the OTA procedure for these 3 firmwares in this sequence (failing to follow this specific order might temporarily or permanently brick your device):
 1. Flash the latest version of InfiniTime. The file to upload is named **pinetime-mcuboot-app-dfu-x.y.z.zip**. Here is the link to [InfiniTime 1.0](https://github.com/InfiniTimeOrg/InfiniTime/releases/download/1.0.0/pinetime-mcuboot-app-dfu-1.0.0.zip).
 2. Update the bootloader by applying the OTA procedure with the file named [**reloader-mcuboot.zip** from the repo of the bootloader](https://github.com/JF002/pinetime-mcuboot-bootloader/releases/download/1.0.0/reloader-mcuboot.zip).
 3. Install the recovery firmware by applying the OTA procedure with the file named [**pinetime-mcuboot-recovery-loader-dfu-0.14.1.zip** from the version 0.14.1 of InfiniTime](https://github.com/InfiniTimeOrg/InfiniTime/releases/download/0.14.1/pinetime-mcuboot-recovery-loader-dfu-0.14.1.zip).
 You'll find more info about this process in [this wiki page](https://wiki.pine64.org/wiki/Upgrade_PineTime_to_InfiniTime_1.0.0). You can also see the procedure in video [here](https://video.codingfield.com/videos/watch/831077c5-16f3-47b4-9b2b-c4bbfecc6529) and [here (from Amazfish)](https://video.codingfield.com/videos/watch/f7bffb3d-a6a1-43c4-8f01-f4aeff4adf9e)
 ### From version > 1.0
 If you are already running the new "1.0.0" bootloader, all you have to do is update your version of InfiniTime when it'll be available. We'll write specific instructions when (if) we release a new version of the bootloader.
 ### Firmware validation
 The bootloader requires a (manual) validation of the firmware. If the watch reset with an updated firmware that was not validated, the bootloader will consider it as non-functioning and will revert to the previous version of the firmware. This is a safety feature to prevent bricking your device with a faulty firmware.
 You can validate your updated firmware on InfiniTime >= 1.0 by following this simple procedure:
 - From the watchface, swipe **right** to display the *Quick Actions menu*
 - Open the **Settings** app by tapping the *gear* icon on the bottom right
 - Swipe down and tap on the entry named **Firmware**
 - This app shows the version that is currently running. If it's not validated yet, it displays 2 buttons:
    - **Validate** to validate your firmware
    - **Reset** to reset the watch and revert to the previously running version of the firmware
 ## InfiniTime 1.0 quick user guide
 ### Setting the time
-By default, InfiniTime starts on the digital watchface. It'll probably display the epoch time (1 Jan 1970, 00:00). The time will be automatically synchronized once you connect on of the companion app to your PineTime using BLE connectivity. InfiniTime does not provide any way to manually set the time for now.
+By default, InfiniTime starts on the digital watchface. It'll probably display the epoch time (1 Jan 1970, 00:00).

 - [How to upgrade Over-The-Air (OTA)](#how-to-upgrade-over-the-air-ota)
    - [Using Gadgetbridge](#using-gadgetbridge)
    - [Using NRFConnect](#Using-nrfconnect)
 - [How to flash InfiniTime using the SWD interface](#how-to-flash-infinitime-using-the-swd-interface)
 ## InfiniTime releases and versions
 All releases of InfiniTime are available on the [release page of the GitHub repo](https://github.com/InfiniTimeOrg/InfiniTime/releases).
 Versions that are tagged as **RELEASE CANDIDATE** are pre-release versions, that are available for testing before actually releasing a new stable version. If you want to help us debug the project and provide stable versions to other user, you can use them. If you want stable and tested version, you should not flash these release candidate version.
 Release files are available under the *Assets* button.
 ## How to upgrade Over-The-Air (OTA)
 OTA is the easiest method to upgrade InfiniTime. Note that it's only possible is your PineTime is already running InfiniTime (>= 0.7.1).
 2 companion apps provide support for OTA : 
 - [Gadgetbridge](https://gadgetbridge.org/) (open source, runs on Android, [available on F-Droid](https://f-droid.org/packages/nodomain.freeyourgadget.gadgetbridge/)). 
 - [NRFConnect](https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Connect-for-mobile) (close source, runs on Android and iOS).
 Both applications need you to download the **DFU file** of InfiniTime. This file contains the new version of InfiniTime that will be flashed into your device. It's called **dfu-x.y.z.zip** (ex: dfu-0.9.0.zip) in the release note.
 ![Dfu file](dfuFile.png )
 ### Using Gadgetbridge
 Launch Gadgetbridge and tap on the **"+"** button on the bottom right to add a new device:
 ![Gadgetbridge 0](gadgetbridge0.jpg)
 Wait for the scan to complete, your PineTime should be detected:
 ![Gadgetbridge 1](gadgetbridge1.jpg)
 Tap on it. Gadgdetbridge will pair and connect to your device:
 ![Gadgetbridge 2](gadgetbridge2.jpg)
 Now that Gadgetbridge is connected to your PineTime, use a file browser application (I'm using Seafile to browse my NAS) and browse to the DFU file (image-xxx.zip) you downloaded previously. Tap on it and open it using the Gadgetbridge application/firmware installer:
 ![Gadgetbridge 3](gadgetbridge3.jpg)
 Read carefully the warning and tap **Install**:
 ![Gadgetbridge 4](gadgetbridge4.jpg)
 Wait for the transfer to finish. Your PineTime should reset and reboot with the new version of InfiniTime!
 Don't forget to **validate** your firmware. In the InfiniTime go to the settings (swipe right, select gear icon) and Firmware option and click **validate**. Otherwise after reboot the previous firmware will be used.
 ![Gadgetbridge 5](gadgetbridge5.jpg)
 ### Using NRFConnect
 Open NRFConnect. Swipe down in the *Scanner* tab and wait for your device to appear:
 ![NRFConnect 0](nrfconnect0.jpg)
 Tap on the *Connect* button on the right of your device. NRFConnect will connect to your PineTime and discover its characteristics. Tap on the **DFU** button on the top right:
 ![NRFConnect 1](nrfconnect1.jpg)
 Select **Distribution packet (ZIP)**:
 ![NRFConnect 2](nrfconnect2.jpg)
 Browse to the DFU file you downloaded previously, the DFU transfer will start automatically. When the transfer is finished, your PineTime will reset and restart on the new version of InfiniTime!
 Don't forget to **validate** your firmware. In the InfiniTime go to the settings (swipe right, select gear icon) and Firmware option and click **validate**. Otherwise after reboot the previous firmware will be used.
 ![NRFConnect 3](nrfconnect3.jpg)
 ## How to flash InfiniTime using the SWD interface
 Download the files **bootloader.bin**, **image-x.y.z.bin** and **pinetime-graphics-x.y.z.bin** from the release page:
 ![Image file](imageFile.png )
 The bootloader reads a boot logo from the external SPI flash memory. The first step consists in flashing a tool in the MCU that will flash the boot logo into this SPI flash memory. This first step is optional but recommanded (the bootloader will display garbage on screen for a few second if you don't do it).
 Using your SWD tool, flash **pinetime-graphics-x.y.z.bin** at offset **0x0000**. Reset the MCU and wait for a few second, until the logo is completely drawn on the display.
 Then, using your SWD tool, flash those file at specific offset:
 - bootloader.bin : **0x0000**
 - image-x.y.z.bin : **0x8000**
 Reset and voilà, you're running InfiniTime on your PineTime!
 If you are using OpenOCD with a STLinkV2, you can find more info [on this page](../openOCD.md).
 ## How to synchronize the time
 ### Using Gadgetbridge
 Good news! Gadgetbridge **automatically** synchronizes the time when connecting to your PineTime!
 ### Using any Chromium-based web browser
 You can use it from your PC, Mac, Android. Browsers now have BLE support.
 https://hubmartin.github.io/WebBLEWatch/
 ### Using NRFConnect
 You must enable the **CTS** *GATT server* into NRFConnect so that InfiniTime can synchronize the time with your smartphone.
 Launch NRFConnect, tap the sandwich button on the top left and select *Configure GATT server*:
 ![NRFConnect CTS 0](nrfconnectcts0.jpg)
 Tap *Add service* and select the server configuration *Current Time service*. Tap OK and connect to your PineTime, it should automcatically sync the time once the connection is established!

 # Updating InfiniTime
 If you just want to flash or upgrade InfiniTime on your PineTime, this page is for you! If you want more information about the software and the update procedure, check out [this](/doc/gettingStarted/about-software.md) page.
 ## Checking the version of InfiniTime
 You can check the InfiniTime version by first swiping right on the watchface to open quick settings, tapping the cogwheel to open settings, swipe up until you find an entry named "About" and tap on it.
 ![InfiniTime 1.0 version](version-1.0.jpg)
 PineTimes shipped after June 2021 will ship with the latest version of [the bootloader](https://github.com/JF002/pinetime-mcuboot-bootloader/releases/tag/1.0.0) and [recovery firmware](https://github.com/InfiniTimeOrg/InfiniTime/releases/tag/0.14.1)
 The bootloader is run right before booting into InfiniTime. It is easily recognizable with its white pine cone that is progressively drawn in green. It also displays its own version on the bottom (1.0.0 as of now).
 ![Bootloader 1.0](bootloader-1.0.jpg)
 ## Updating with companion apps
 To update your PineTime, you can use one of the [compatible companion applications](/README.md#companion-apps).
 The updating process differs slightly on every companion app, so you'll need to familiarize yourself with the companion app of your choice.
 All releases of InfiniTime are available on the [release page of the GitHub repo](https://github.com/InfiniTimeOrg/InfiniTime/releases) under assets.
 To update the firmware, you need to download the DFU of the firmware version that you'd like to install, for example `pinetime-mcuboot-app-dfu-1.6.0.zip`, and flash it with your companion app.
 We have prepared instructions for flashing InfiniTime with Gadgetbridge and NRFConnect.
 - [Updating with Gadgetbridge](/doc/gettingStarted/ota-gadgetbridge.md)
 - [Updating with NRFConnect](/doc/gettingStarted/ota-nrfconnect.md)
 ## Firmware validation
 Firmware updates must be manually validated. If the firmware isn't validated and the watch resets, the watch will revert to the previous firmware. This is a safety feature to prevent bricking your device with faulty firmware.
 You can validate your updated firmware on InfiniTime >= 1.0 by following this simple procedure:
 - From the watchface, swipe **right** to display the *quick settings menu*
 - Open settings by tapping the cogwheel on the bottom right
 - Swipe up until you find an entry named **Firmware** and tap on it
 - If the firmware is not validated yet, you can either validate the running firmware, or reset and revert to the previous firmware version

 - Buttons should generally be at least 50px high
 - Buttons should generally be on the bottom edge
 - Make interactable objects **big**
 - Recommendations for inner padding, aka distance between buttons:
 	- When aligning 4 objects: 4px, e.g. Settings
 	- When aligning 3 objects: 6px, e.g. App list
 	- When aligning 2 objects: 10px, e.g. Quick settings
 - When using a page indicator, leave 8px for it on the right side
 	- It is acceptable to leave 8px on the left side as well to center the content
 - Top bar takes at least 20px + padding
 	- Top bar right icons move 8px to the left when using a page indicator
 - A black background helps to hide the screen border, allowing the UI to look less cramped when utilizing the entire display area.

 /**
 * Different weather events, weather data structures used by {@link WeatherService.h}
 *
 * How to upload events to the timeline?
 *
 * All timeline write payloads are simply CBOR-encoded payloads of the structs described below.
 *
 * All payloads have a mandatory header part and the dynamic part that
 * depends on the event type specified in the header. If you don't,
 * you'll get an error returned. Data is relatively well-validated,
 * so keep in the bounds of the data types given.
 *
 * Write all struct members (CamelCase keys) into a single finite-sized map, and write it to the characteristic.
 * Mind the MTU.
 *
 * How to debug?
 *
 * There's a Screen that you can compile into your firmware that shows currently valid events.
 * You can adapt that to display something else. That part right now is very much work in progress
 * because the exact requirements are not yet known.
 *
 *
 * Implemented based on and other material:
 * https://en.wikipedia.org/wiki/METAR
 * https://www.weather.gov/jetstream/obscurationtypes
 * http://www.faraim.org/aim/aim-4-03-14-493.html
