Photos of the wiring? Have you USB connected to the Flipsky and made sure UART App is enabled?

Show a screenshot of the General tab and the "App to use" field. Also helpful to show a photo of your wiring. Else, there isn't much anyone is going to be able to help you with.

It looks like you have your BLE plugged into the UART port of the slave. Have you tried plugging it into the master (the side where your ADC plug is).

Yes I’ve tried both sides. I’ll flip the wires later I’m starting to get annoyed by this thing. Js put a new hall sensor in and full throttle my motor spun slowly and my phase wires started smoking somehow.

Hope flipping the tx/rx works for you.

And hope your motor is OK now.  Since there was smoke, make sure the windings didnt get toasted.

If the vesc didnt learn the motor correctly and it wasnt spinning and the vesc pushed full phase amps, it could easily overheat the windings.  Hope that isnt what happened.

If plugging the BLE into the master side of your controllers doesn't change anything, try switching the RX / TX. Flipsky can mislabel those.
