Ok, I've read all the best practice post and many others and I need to get a straight answer here before sending this 130 right back to the seller. Is it true that that it will not connect to a dual speed/cadence BLE sensor at all? Pairs, but no connection. Blinking little icons never stop, no data. I've tried everything. THREE different sensors on different bikes, different brands, one is a common one, Wahoo (dual BLE/ANT+). Nothing. Don't start about ANT+, I am not going out and buying a bunch of new sensors when I already have 3 perfectly fine BLE sensors.
I thought maybe some Bluetooth interference somewhere. Turned off the Bluetooth on the phone, on the Connect app, etc. Removed a battery from an old bike computer that worked fine with all THREE, etc. Nothing.
I also have a Polar H7 BLE strap. That pairs and connects flawlessly, so sure seems to be related to the speed/cadence/BLE combination.
Finally, about the Wahoo dual speed/cad sensor .. it is also dual BLE/ANT+. So when I pair the Wahoo, it gives me two options, one is ANT, select BLE, pairs, but not connection, endless blinking. Select ANT+ .. boom. It works. I saw another post where someone asked Garmin and got a reply to the tune of "strongly recommend separate speed and cadence devices or going ANT", or something like that.
This to me is proof that dual Speed/Cadence BLE-only sensors are just NOT supported at all, none of them. Am I right?
