K ++ flight controller is connected to the ground defense module, why is it not working?

Answer:

1. Check if the ground radar module wiring is normal (connect to CAN1 port)

2. Check the upper right corner of the Flight Defense Manager APP, and the switch of the ground defense radar module is turned on (only on the APP)

3. There may be a problem with the quality of the ground protection radar. Please return to the manufacturer as soon as possible to investigate the cause.
