Adding a sensor to mavlink stream

Hi @EliotBR

That is actually a Dataflash Log. It doesn’t have mavlink communication, so it is not very relevant to your use case.

This seems to work here:

from pymavlink import mavutil
master = mavutil.mavlink_connection('udpout:localhost:14550', source_system=1)
master.mav.statustext_send(mavutil.mavlink.MAV_SEVERITY_NOTICE, "Qgc will read this".encode())

change localhost to the topside IP, if your qgc read this message, the communication is working and you can try the named_value_float message next.
