    voxl-mavlink seems to support only MAVLink 2.
    https://gitlab.com/voxl-public/voxl-sdk/third-party/voxl-mavlink/-/tree/master/files

    The third-party application I use uses MAVLink1 in part, which results in an error (actually no response).
    Do you plan to support MAVLink v1.0 in the future?

      To reproduce:
      set MAV_PROTO_VER to 1 (always use version 1)
      VOXL cannot get any information from PX4.

        @JP-Drone Until now we didn't know that there was a use case for v1.0. What is the third party application?

          @Eric-Katzfey
          It's UgCS.
          The default is v1.0.
          It's possible to set v2 or auto.
          But if I set auto, it fails to connect.
          Because it tries to negotiate with v1 at first and VOXL doesn't handle it.

            @JP-Drone Does it work if you set it to v2?

              @Eric-Katzfey Yes, it works.
              I am not sure if changing the settings on the GCS side will affect the connection to other copter.
              But now it seems fine.
              Thanks.
