GPS Error And Issues Setting Up Obstacle Avoidance



  • When I set COM_OBS_AVOID to 1, the drone will immediately go into Not Ready mode. After doing some looking, I think it's because GPS shows as ERROR. I am not quite sure why the GPS has an error, but it's been like this for a couple of days, even before I tried to setup obstacle avoidance. The logs show a 'No known GPS device found' error which could be substantial:

    The GPS model is MATEKSYS M8Q-5883 GPS Module, and the light on it is solid red. Apparently a flashing blue light means it is 3D fixed, but I'm not sure if that means anything.

    I am not sure if this is a hardware issue or if there is something specific I need to do to setup the GPS so that it is not in error state. When I bring the drone outside, it does show that it gets GPS connection, even though GPS is in error state.

    Any suggestions?

    Is that version of GPS module supported in the version of PX4 you are using? Is it wired properly to your flight controller as well?
