    Hi @Stefan-Amundarain
    Not all FTDI cables are the same. There are literally over a dozen variations out there.
    If the specific FTDI cable requires a "VTREF" to set the logic levels, then a VCC is needed as on Ascend's example. If you use one that is USB powered and TTL levles, then likely it is already set for 3.3V, and no power is required.
    So, please double check your specific FTDI cable before following any tutorials you may see and make appropriate mods as needed.

    Thanks!

    @Vinny @brahim @Eric-Katzfey We're still running into the issue of no meaningful data being sent to gazebo. The only data is still the heartbeat packets.
    We're referencing: https://docs.modalai.com/voxl2-PX4-hitl/

    We've done the steps up to: docker run --rm -it --net=host --privileged -e DISPLAY=$DISPLAY -v /dev/input:/dev/input:rw -v /tmp/.X11-unix:/tmp/.X11-unix:ro voxl-gazebo-docker ./run_gazebo.bash

    and

    qshell dsp_hitl status which is telling us about the heartbeat only.

    Also, we tried the archived instructions to see if we would get a different output.

    The FTDI cable used is the same, but the serial port closed issue has stopped. Don't know why.

    The warning for SDF I feel like is the source of the problem.

      @Alexander-Saunders Are you doing xhost + before running docker?

        @Eric-Katzfey The latest attempts, yes. After running that and

        docker run --rm -it --net=host --privileged -e DISPLAY=$DISPLAY -v /dev/input:/dev/input:rw -v /tmp/.X11-unix:/tmp/.X11-unix:ro voxl-gazebo-docker ./run_gazebo.bash
        

        gazebo will open up. The issue is connect gazebo with VOXL2 to run in HITL mode. I've followed two of the video from Modalai and Ascend exactly with no luck. Also went through the documentation again.

        All instances are being ran on the host computer. When comparing the image from above to docs, we are only getting heartbeat packets.

          @Alexander-Saunders The heartbeat counter is the amount of heartbeat messages being sent out, not received. So you are not getting anything on the serial port.

              @Alexander-Saunders Definitely looks like a permissions issue of some sort in your system.

                @Eric-Katzfey Are you suggesting giving the file/repo permissions with

                xhost si:localuser:root
                

                Also we are using the FDTI cable provided with the ESC AND USB C to A to connect to host.

                  @Alexander-Saunders I'm only suggesting that there is a permissions problem of some sort. I don't see that on my machine so just trying to figure out what is different in your environment.

                          @Alexander-Saunders iris_hitl.sdf is part of the docker image so it will be the same.

                                @Alexander-Saunders We have quite a few customers using HITL successfully and they are using the instructions in the document so I'm thinking there is something in your environment that is causing the issue. Do you have access to a different Linux machine that you can use?

                                  @Eric-Katzfey Update:

                                  We switched some of the wires for the FTDI cable and now receiving data. We went back to following the HITL docs along with https://forum.modalai.com/topic/3511/serial-port-closed-and-other-hitl-errors/9 . We have the drone running in HITL via QGC and running the voxl-px4-hitl command. Despite this, gazebo is still not showing the drone or connecting. Could the issue possibly be with the Dockerfile that reflects bionic instead of focal since that had to be changed for the image to be pulled? We also tried running ./run-docker.sh within the directory and received docker run --help.

                                    @Alexander-Saunders Looks better now. What does the dsp_hitl start command look like now? Seems like it is setup for VIO only.
