Python script connected to voxl wifi, not sure how. Need help understanding.

Noe Medrano

Maybe someone can help me find an explanation for this. I have been using the mavsdk (python) and the jmavsim. So fart I have been testing my scripts using the jmavsim and QGC. I am able to connect to the "drone" in the sim and view the same files that are listed in QGC. This is with no voxl connected to the computer. So as I was looking for away to connect to the voxl and download the ulogs. I did not change any code on python scripts. The voxl happened to be powered and the wifi antenna connected. So my scripts connected to the voxl instead of the simulator.

When I was working with the sim only i was using the following to connect to the "drone".

drone = System()
await drone.connect(system_address="udp://:14550")

I have made no changes to my python scripts. Is there something in the voxl or the mavsdk that would connect it to the voxl's wifi instead of the sim? The IP of the voxl is nowhere in my code nor connected to the computer. Before I connect to the drone the following is code appears.

async def launch_px4():
    # Launch the PX4 simulator
    px4_directory = '/home/nm/dev/PX4-Autopilot'
    run_px4 = f'cd {px4_directory} && HEADLESS = 1 make px4_sitl jmavsim'
    px4_process = subprocess.call(['gnome-terminal', '--', 'bash', '-c', run_px4])
    return px4_process

I am just trying to understand what is happening so I know how to edit and create what we need.

Thanks.

btw, all your suggestions are working. Thank you.
