"""Beacon application
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Flash the relatively powerful HRS LED repeatedly, mostly for signaling purposes.
|
|
|
|
Frequency and intensity can be changed.
|
|
|
|
The blinking is handled by the HRS, so this app consumes very little power.
|
|
With BLE and/or step counter disabled and blinking frequency set to the minimum,
|
|
the watch's battery will last for many days.
