I know this question isn’t super specific, but for requirements-gathering and solution research purposes I just need to ensure that its possible to get telemetry data in a real-time live streaming manner via the MAVSDK before I dive into it too deep.
Yes, that’s what it does. Now it only receives what is sent via MAVLink messages.
If you want more control and also look at internal PX4 data that is published via uORB, check out the new ROS 2 bridge.
