I have a Garmin 830 (SW 9.40) and the RTL515 (FW 3.33) and UT800 (FW 2.40).
I originally paired the RTL515 to the Edge 830, and the RADAR and Light worked OK, though sometimes the RADAR would go out, and reconnect during a ride.
recently, I bought a Varia UT800 headlight, and when I paired it, either the RADAR works or the Lights work, but never both, at least not for long.
It seems like the light pairing is conflicting with the radar pairing.
I've seen other forum posts where people tried pairing the lights through the add "light" section and then the lights show up, but then the Radar disconnects.
This is very frustrating. I have decided to unpair the lights since it keeps bumping the Radar's connection, and that is the most important one. I really wish the light network would work, bit it is so buggy I gave up. I've put in about 6 hours of messing with it over many rides, and it just makes me angry.
Is there a fix, or is this faulty hardware?
