"""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.
