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.
* Make firmware updating more foolproof and fix bugs
* No need to manually handle overflow
* Make startTime TickType_t
* Don't process TouchEvents::None
* Fix sleep getting re-enabled issue more directly
* Allow multiple wakeup modes at the same time.
This commit adds multiple wakeup modes support.
It does so by storing them as a uint8_t bitfield enum.
It changes the following functions:
Since multiple modes can be on now, older version would not cut it:
WakeUpMode getWakeupMode() -> std::bitset<3> getWakeUpModes()
Where each bit corresponds to a WakeUpMode
We still need a way to check whether a specific wakeup mode is on, so:
bool isWakeUpModeOn(const WakeUpMode mode)
This function was changed to work correctly with the new implementation.
setWakeUpMode(WakeupMode mode, bool enable)
Previously, systemtask would exit SystemTask::OnTouchEvent() if the wake
up mode was None or RaiseWrist, to prevent waking up when a touch was
received. However, after enabling using multiple WakeUpModes, this
caused a bug where when RaiseWrist was checked with SingleTap or
DoubleTap, the tap detection wouldn't work.
This commit fixes that bug.
Next commit will update the settings WakeUpMode select UI to reflect these changes.

Replaced the use of the standard library trig functions with a LUT-based
implementation instead. The standard library implementations produce
more accurate results but the usage here doesn't need that. This ends up
saving nearly 7kB of binary size.
