@Wondosen You're building voxl-tflite-server which is part of SDK 1.4.4, while calling install_build_deps.sh qrb5165 dev will pull the dependencies for a much newer version of voxl-tflite-server than you're using.

Try running ./install_build_deps.sh qrb5165 sdk-1.4

@psafi So which driver do you use in PX4 then? Do you have a custom driver since you modified it to use UART instead of UAVCAN?

@psafi J10 is a UART mapped to the applications processor (Linux). Most of PX4 runs on the DSP and uses UARTs mapped to the DSP. To use J10 you would have to include the driver module into the applications processor build and then start it in the start script.

@psafi Which sensor is it?

@andrevs01 But, the configuration of what Mavlink broadcasts can be different than what it actually broadcasts. It will only broadcast something that it is configured to broadcast if it is receiving data from the required topic(s) internally.

@andrevs01 No, what Mavlink broadcasts is configured separately from anything related to ROS2

@Wondosen How are you running ./install_build_deps.sh?

@Alex-May And can you post the entire output from voxl-px4 -d?

@Alex-May It really looks like there is no communication going on between the GPS and the VOXL 2. Can you attach an oscilloscope to the rx and tx lines to look for activity? Usually the M10 units come up and start sending NMEA strings at 9600 so you would be able to detect that on the scope.
