Someone gave to me this scooter i’m trying to fixing! The scooter run perfectly but bluetooth connection doesn’t work by App! I discovered whilw i took a part, that there is a bluetooth module and “the wire has been cutter, the module is on the bottom close to the rear wheel, Do you know how can I connect the bluetooth module? Because all the connectors of the electronic controller are full connected!!
thanks for help
