I use both the Garmin front and rear lights daily on my commute from/to work.
Before FW 25.24 the light network always worked from the first time.
Now I need to cycle the lights a couple of time, before both are properly connected to my Edge.
Sometimes I need to toggle the auto network option on the Edge for the lights to connect.
I always use following sequence:
- turn on Edge (wait for it to start completely)
- turn on headlight (wait for it to connect to the Edge)
- turn on read light
