I have a only-ant+ supported hrm premium and radar rtl516 both ant+ and ble supported. I tried to connect the hrm premium with the fr 255 but it disconnects one or two seconds later then when I enter the connection page of the watch than reconnect. when I return the watch face then disconnect again. this goes ever time. And the same for the radar rtl 516. I check the supoorted equipments, the hrm premium and the radar rtl 516 arent listed there. but are there any different connectivity protocol which I find weard or I simply have a bug? the other problem is that the watch tries to connect over ant+ for that reason I have no option to connect it over ble option for the radar. I explored that garmin gives priority to ant+ while dual connectivity is available. but how can I omit the ant+ which is misbehaving?
