Thought this thread was here somewhere already, but couldn't find it.
Had this a few times but not as pronounced as yesterday.
20min into my ride, I lost contact with my Cad, HRM, Power, Speed sensors.
Still registering on my 935 watch.
Restarted the 130 and they appeared again nicely. For 10s.
Hmmm.
Turned off the phone connection and they instantly appeared again.
I've had it before, but usually they come back after a few minutes.
Looks like the Ant+ part disconnects when doing a bluetooth transfer with the phone and turns back on again when it's done.
On yesterdays ride, I was out of cell coverage, so GC on the phone couldn't sync.
