I’m trying to setup a raspberrypi 4B to forward mavlink messages to my CrossBow Mini antenna tracker. I think my problem is the serial port on the pi, but I’ve done all the recommended things.
enable serial, disable login, disable bluetooth using btoveralay in /boot/config.txt, blacklist bluetooth
But when I run this:
mavproxy.py --master udp:pi:14550 --out /dev/serial0:57600
The crossbow doesn’t receive anything. Mavproxy is working because it responds with this:
Connect udp:pi:14550 source_system=255 Log Directory: Telemetry log: mav.tlog Waiting for heartbeat from pi:14550 MAV> Detected vehicle 1:1 on link 0 online system 1 FBWA> Mode FBWA AP: ArduPlane V4.3.0dev (e2a132ed) AP: Tims-MacBook-Pro.local Received 1576 parameters (ftp) Saved 1576 parameters to mav.parm Flight battery 100 percent AP: PreArm: Fence requires position
I know the tracker can receive telemetry because I have got it to work by connecting a SiK telemetry receiver to the same pin and got telemetry no problem.
