Following this guide, using an mRo pixracer & a raspberry pi 5: Raspberry Pi Companion with Pixhawk | PX4 Guide (main)
When I connect the companion computer & pi as over uart as described in the guide, then attempt to launch MAVROS on that serial port, I get no heartbeat.
Things I’ve checked:
- Wiring is correct (tx / rx are swapped, ground is connected)
- Mavlink is configured properly (baudrate=57600, on TELEM2 port, mode is set to onboard computer)
One question I have is if connecting to it via one of the TELEM ports is supposed to make a new serial device show up in the /dev directory, (i.e. connecting via microusb prompts /dev/ttyACM0 to become available).
Would just like to know if anyone has experienced something similar, if there’s anything I’m missing, or if there are any useful tools to debug this issue. Thanks!
