I have tried using HITL gazebo without ROS on ubuntu but it seems there is no connection between my hardware and the simulation (or QGC). The are no errors printed at all, but after gazebo opens, there is not response from the pixhawk and there is no response after opening QGC. I am using px4_fmu-v3…

[FIXED] So I am using px4-fmuv2, and unfortunately in this case pwm_out_sim is commented out in the file PX4-Autopilot/boards/px4/fmu-v2/default.cmake. So uncomment this and you can see the rotors spinning after arming the drone in QGS.

Hey @Themaksiest I was able to resolve this issue by running this command in the src/Fimrware folder “git checkout v1.10.1” If you didnt run this command after you cloned PX4 repository then you will have to start again. You only upload the firmware v1.10.1 into pixhawk, however, it is not enough…

@mehdi786 You can simply use gazebo Tools/sitl_gazebo/worlds/empty.world Instead of gazebo Tools/sitl_gazebo/worlds/iris.world I will update the docs accordingly

I have the same problem. If I open QGC, it just says waiting for connection. The question semes connect to upon.

Hey @mehdi786 . Thanks for the response. After some time of recloning and remaking I finally got to the point where iris model was visible in the simulation. I still could not make the simulation connect to QGC and FC.

@Chris_iav We are working on it in https://github.com/PX4/PX4-SITL_gazebo/pull/651

@cschindlbeck HIL is not related to a qgroundcontrol version - it works whether or not QGC is running Have you tried pulling the PR?

so the battery parameter issue still exists, is this causing an AUTODISARM? For some reason, the Led I/O B/E is flashing red which apparently does’t connect to the vehicle as shown in qgroundcontrol

@bperseghetti Any chance you have any insights?

@cschindlbeck can you list your FCs “changed” params, specifically hil_enable and sys_autostart, firmware version, QGC version, model you are trying to run in sitl_gazebo, the way you are connected from computer to FC, how you are launching it, commit sitl_gazebo is on for you, ubuntu version, gazeb…

@Jaeyoung-Lim great to hear, is there a workaround until the pull request is through? Reverting to an older qgc version or changing the parameter names in the firmware?
