Previously, pressing the back button would close the alarm app anyway. Now if you press on it and the popup with information is open, it will first close and the second press will close the application
Always returning 0 (when `MYNEWT_VAL_BLE_LL_RFMGMT_ENABLE_TIME` is not defined), rather than a time near to the current tick, causes an issue in at least one place: `ble_ll_adv_sm_start()`, where the calculation of `delta` overflows when the system timer is at 0x80000000 or above -- causing an incorrect, huge adjustment to be made to the scheduled time, ultimately stopping adverts from being sent.
This issue was caused by DateTime::SetCurrentTime() that would not update the internal state of the class : dayOfWeek, Month, Year were not properly updated according to the current time.
`xTaskGetTickCount()` returns a `TickType_t`, which is defined as an
`uint32_t`. This is compared to the `bpm` variable, which is a `int16_t`
in the range of 40 to 220 as defined in the constructor.
```cpp
lv_arc_set_range(bpmArc, 40, 220);
```
Just assume that `bpm` is greater than 0, as this
would result in a divison by zero or negative values, which would
unintentionally underflow to a very large number.
* docs: Fix a few typos
There are small typos in:

- src/components/ble/NimbleController.cpp
- src/libs/mynewt-nimble/CODING_STANDARDS.md
- src/libs/mynewt-nimble/docs/btshell/btshell_GAP.rst

Fixes:
- Should read `milliseconds` rather than `miliseconds`.
- Should read `unnecessary` rather than `uncesseray`.
- Should read `target` rather than `tharget`.
- Should read `project` rather than `projct`.
- Should read `preferred` rather than `prefered`.
- Should read `functioning` rather than `functionning`.
- Should read `forever` rather than `forver`.
- Should read `existing` rather than `exisiting`.
On power up, advertise aggressively for at least 30 seconds then switch
to a longer interval to conserve battery life. This fast/slow pattern
is designed to balance connection response time and battery life.
When a disconnect event is received restart the fast/slow pattern.
When a failed connect event is received, restart the fast/slow pattern.
When the screen is activated and ble is not connected, restart the fast/slow pattern.
This pattern is consistent with Apple's BLE developer standards (QA 1931).
Start advertising aggressively when powered on then
slow down linearly over 75 seconds. This will conserve
battery by not advertising rapidly the whole time we
are seeking a connection. The slowest rate is
approximately once every 4.5 seconds to balance
responsiveness and battery life.
We use a fixed advertising duration of 5 seconds and start
with a 62.5 ms advertising interval. Every 5 seconds
(the advertising duration) we step up to a larger
advertising interval (slower advertising). We continue
to increase the advertising interval linearly for
75 seconds from the start of advertising. At 75 seconds
we have an advertising interval of 4.44 seconds which we
keep until connected. A reboot will restart the sequence.
When we receive a disconnect event we restart the sequence
with fast advertising and then slow down as described above.
Note that we are not using the BLE high duty cycle setting to
change the advertising rate. The rate is managed by repeatedly
setting the minimum and maximum intervals.
The linear rate of decrease and the slowest interval size
were determined experimentally by the author. The 5.3 Core
spec suggests that you not advertise slower than once
every 1.2 seconds to preserve responsiveness but we
ignored that suggestion.
