I used this method successfully one time and it was great. However, when I tried to connect from my Android device a second or further time, I was not able to use the controller as a keyboard. I tried to rebuild the connection and I'm not asked for a pairing key nor am I directed to the keyboard setup. This is an ongoing issue that I spent several hours troubleshooting.
I am able to connect on the Mac with the Mac specific version of Bike Control, but I would like the ability to use my Android as a backup.
