"TX queue overflow"

  • I am trying run hitl on voxl 2 in with gazebo and QGC. After opeing gazebo when I open QGC it shows "Tx queue overflow" in gazebo terminal. How to fix it ?

  • TX Overflow happens because you are trying to connect to QGC with the serial connection being leveraged by gazebo for HITL. So what you need to do is open QGC after gazebo is running and connected to the VOXL2. Once this is done, you can only connect to QGC via the UDP connectoin. This can be done by enabling voxl-vision-px4 and voxl-mavlink-server services.

    So you connect to the gazebo via the serial, and QGC via the UDP connection.
