Cause:

After startup, the domain controller attempts to establish a network connection with the radar within 45 seconds. If the connection is successful and radar data is obtained, the radar is recognized. If the connection cannot be established or no radar data is received within 45 seconds, recognition fails.

Troubleshooting Methods:

Check the radar status:

Go to the APP main interface → Device Management → Drone, then scroll down to view the working status of each radar (try clicking Refresh)

• If both the forward and downward radars are not recognized, it is likely due to a power supply line abnormality (the radar is not receiving power). This is especially common after crash repairs or line modifications. It is strongly recommended to check the power supply lines first.

Troubleshooting Methods for Single Radar Not Recognized:‘

1、Disconnect the FPV (if the FPV is short-circuited due to water ingress, it may affect the radar's power supply) and test if the radar is recognized normally.

2、Replace the wiring harness or replace the radar for cross-verification.

3、Replace the main controller, as the issue may be caused by an internal network-related link abnormality in the brain (main controller).
