I can get my nano x receiver and transmitter to work fine bench testing it but a few times I’ve been out riding and stopped to talk and then I can’t get the two to bind once I turn off the transmitter and receiver. I’ve never lost a bind once it has been established.
Seems almost like a temperature issue? It’s still around 50 F (10 C) when I’ve had the issues after riding for a bit. My house sits around 72 F (22 C) when I never have issues with binding.
