Alright so an update.
I have checked with the OEM and the protocol to follow was CAN, not UART.
So I have changed and now I am getting a new message which I don’t know is a step forward or not.
Bad Proximity
I am following this thread as I found it similar to setting up the radar:
Application of TF03 CAN in PixHawk (ArduPilot Firmware) - Blog - ArduPilot Discourse
Second update:
Got the Nano Radar working.The protocol is UART as before,not CAN.My mistake.But the bad proximity error still remains.Probably just a loose wire or the power reaching the nano radar is less than 12V.
