Multi-Drone sim QgroundControl failure

QGroundControl Using QGroundControl

Hello everyone,

I am following up on this previously closed thread: Accel Fail Error for Multi Drone Sim
As mentioned in the docs for multi-vehicle sim,Multi-Vehicle Simulation with Gazebo | PX4 Guide (main)
When I run the commands
PX4_SYS_AUTOSTART=4001 PX4_SIM_MODEL=gz_x500 ./build/px4_sitl_default/bin/px4 -i 1
PX4_GZ_STANDALONE=1 PX4_SYS_AUTOSTART=4001 PX4_GZ_MODEL_POSE="0,1" PX4_SIM_MODEL=gz_x500 ./build/px4_sitl_default/bin/px4 -i 2

This causes both of these drones to fail due to
ERROR [sensors] Accel #0 fail: TIMEOUT!

Running
make px4_sitl gz_x500
makes it work for a single drone but not for the other drone spawned using the previous command

Have you found the solution? I am currently facing the same exact problem

I think it was mostly a resource issue for me. Try exiting other processes or put

export PX4_SIM_SPEED_FACTOR = 0.1 in .profile

Hi, just wanna say thanks for the advice that I was able to run the simulation in 1/10 of its real speed. Btw did you do something about the simulation speed (cause it’s very slow) by tweaking the Gazebo settings or just let it be?
