MAVLink Version 0.9 Navio2 Error

  1. Image and ArduPilot version.
    4.19.83-emlid-v7l and ardupilot 3.6

  2. Detailed problem description. How does observed behavior differ from the expected one?
    Hi folks, when I try to connect me navio/ardupilot to an APM Planner ground control station I get this error.

Critical message: “MAVLink Version or Baud Rate Mismatch” “Your MAVLink device seems to use the deprecated version 0.9, while APM Planner only supports version 1.0+. Please upgrade the MAVLink version of your autopilot. If your autopilot is using version 1.0, check if the baud rates of APM Planner and your autopilot are the same.”

Any ideas on how I can update this to MAVLink 1.0 or 2.0 in the linux terminal? I’m using ROS Kinetic LTS.



As it is said in the error message, it could be baud rate mismatch.

Can you, please, post an output here of:

cat /etc/default/arducopter

Hi Mikahil,

I gave up on APM and went to Mission Planner, works great!

Thanks for help regardless.
