Hi everyone! I have such a flight controller SpeedyBee F405 V3 up to 6 UART instead of GPS connected rpi3 as indicated in the article Communicating with Raspberry Pi via MAVLink — Dev documentation
On the rpi3 side, I did everything and I get a link 1 down error
Can someone explain what exactly I’m doing wrong. I think I have errors in setting up the drone through ArduPilot. What should I pay attention to when creating a drone configuration so that I can control the drone through mavlink2 (rpi3).
