I have a Samsung Galaxy S7 Edge (running Android 7.0) and a Wahoo RFLKT+. I can get the Wahoo RFLKT+ to pair to the Ride With GPS app using the Settings -> Bluetooth and Sensors -> External Displays. I pair form the External Displays screen and I get the Ride With GPS in large letters and the time showing. I also get prompted to update the RFLKT+, but when I go to the Wahoo Firmware app, it shows that it already has the latest firmware version.
Then, when I go to Record my Ride, the RFLKT+ goes blank. So, when I turn the RFLKT+ back on, it won't connect with Ride With GPS. It just shows Searching .. and never connects. A couple times, I've been able to hold buttons on the RFLKT+ and Searching ... changes to Connecting ... and it actually works.
Any suggestions? Thanks!
