Got the smart lock 2.0, using latest firmware and beta app… each time I try to calibrate the lock it ends up with Bluetooth out of range. Sometime I get a successful calibration but actually it is incorrect as the door is locked when asked t unlock, …etc
Is your phone going to sleep while the calibration takes place? I had faced this once and kept the phone awake by touching the screen continuously. You may also use an app like “Caffeinate”.
