i used to get this all the time and still do sometimes when wireing up a new vesc. it says unable to read the firmware version, make sure the tx and rx pins are correct rxfrom the bt to tx of the vesc and vise versa.thats your message your getting right?
80% it has ben a bad wire connection for me somewhere along the line but I recyle alot of wire. make sure your grnd is good and not flickering intermittently as well as the led on the ble modual make sure its rock steady even if you move all the wires up and down.
if you go into the App section of V-Tool under general and then is the check button for the vesc being paired on and orange or not paired?
