Hi!
So I just bought a used bike which have the quarq sram red power meter installed and I'm having some issues with it..
Doing "all sensor search" on my FR920xt gives me varying results;
- sometimes I get nada
- sometimes I get "power 53901" (which is the number on the crank)
- sometimes I get "power 339", "power 53901" and "speed and cadence sensor
Using only the "power 53911" I get 0w and no cadence. When calibrating I get around -290 or something like that.
Using the other two I get power and cadence. When I try to calibrate it fails with an error 655... something and then disconnects both sensor.
I did the pairing like 5 times on the stationary trainer and as soon as I went outside it disconnected and wouldn't connect again.. Trying to pair outside lifting the bike and turning the pedals or while riding - nada...
I've changed the battery. Backpedaling 5 times doesn't give me any red light.. I don't actually see this much except when I remove and then add the battery again.
I don't know why I sometime find three sensors and at other times find only one. My guess is that the "power 53911" would be the correct one if using a magnet perhaps? There's no magnet on the bike.. so my assumption (as I get watts on the other "power 339") is that it's new enough (2014+) and support use og accelerometer..?
It's this one:

So.. any clues? I'm kind of lost :)
