Bad Proximity error with mmWave radar

Display proximity UI not show distance (red circle), but the radar work fine at telemetry data RNGFND2.
I use 1.3.81.

Guess what the “BAD Proximity” error means ?
Your proximity sensor is not operating, perhaps a bad sensor setup ?
What are your parameters ?

Hi @Eosbandi ,
the sensor is a milimetric nano radar and It seems to be reading distances (see the video), but it’s true that the “BAD RADAR” message appears. These are my settings:
rngfnd2_type = 11
rngfnd2_clear = 10
serial2_protocol = 9
serial2_baud = 115
prx1_type = 4
