I'm having issues, where the head unit would constantly reconnect heart-rate and cadence sensors (the ones that come in the sensor bundle), and also the Flux 2 trainer.
The sensors seem to reconnect after a short while, and while the beeping is annoying - it is manageable.
The connection issues with the trainer are a real pain though. Occasionally, when the trainer is reconnected, my free ride trainer settings are reset (eg. from power target ir resets to a 1% grade).
To make things worse - it would decide to finally not connect anymore. It does keep the connection in a way that it still reports the power data from the trainer but I can no longer control it - change the power target or grade.
Every time the trainer disconnects, I have to check for it to reconnect and check whether it keeps the correct mode. And can never know whether I'll actually be able to control it because of the disconnection mentioned above.
The device is pretty new - haven't even gotten it outside yet. Latest firmware there. Using only the sensors that came in the sensor bundle.
The trainer itself is also on the latest firmware and I bought it new recently.
Looking at the workout results, I can see that the power data is dropping to 0 over 20 times during a 1hr20min workout.
