i am using a ArduinoBt board for quite some time and it worked great up to now. For some reason i can not pair the board with the default ‘12345’ pass-key anymore. The board shows up in my bluetooth device list with it’s name ‘ARDUINOBT’ but the pairing fails.
- Is it possible to reset the pass-key to the default one without a working bluetooth connection?
- If not, is it possible to wire the ArduinoBt board to a usb port to send it a new pass-key?
Thanks a lot,
