Are you sure?
For me upating the stream rate works using extras.txt file but when I try to change the baud rate, it doesn't work. I used only 2 lines in extras.txt file.
mavlink start -d /dev/ttyS1 -b 38400 -r 1000
Also, since I am using RFD 900x as telemetry module, I changed the baud rate of the telemetry module in both air and ground module to 38400. Is there any other setting that I am missing?
Should I be changing any parameter in QGround Control? Also I tried adding a connection in the comm link section in QGroundControl which also did not work out.In mission planner, you set the baud rate while trying to connect to the com port and selecting the lower baud rate did not work.
Also could anyone help me figure out where the baud rate for the vehicle telemetry to the ground station (not the RC for throttle etc) is hard-coded in the init.d file? I can't seem to find it. Simply doing a search of -b returns no result in the following firmware folder. Or am I looking at the wrong location?
This is the file where I am looking at:
It seems to have a section for frsky_telemetry for the RC control.
I am using Pixhawk 3 Pro with PX4 firmware version 1.8.1.
Should I be going back a few versions to see this parameter?
