Hi, how do I pair the Varia with the second device? When I turn the device on in pairing mode by holding in the power button it seems to drop the connection with the initial head unit.
the pairing mode is for the light so it can't be controlled from any random device near you. On the other hand anybody can connect to the radar.
I have been using it in group rides where a person with a radar is always on the end of a peloton and other people are getting these notifications to their edge devices.
It is useful when you are riding with somebody slow (wife, kids) - he/she/it will be always on the back and in case you will loose him you will be notified about lost connection to radar :D
