    • RE: GPS Denied Environment with VIO

      @Chad-Sweet Thanks for your reply.

      I am currently running firmware FCv1 - v1.11.3-0.2.3 from that link. I downloaded the image and then uploaded it through QGC as a custom firmware.

      Thanks,

      Karl

    • RE: GPS Denied Environment with VIO

      After much more time trying to troubleshoot this issue, I am still unable to arm my drone. QGC shows that everything is operating correctly except that there are failures for GPS and Pre-Arm Check. Does anyone else have any suggestions on other procedures I could try? My current software setup is the same that I have described above.

      Thanks!

      Hello @Gordon8,

      Thanks so much for your advice. I reset all the parameters in QGC and reloaded ekf2_indoor_vio and sensors_disable_gps_mag.

      I am unfortunately still running into the same issue as before. Arming is denied because of a generic gps error. I have disabled gps and edited other parameters that are supposed to allow arming without gps.

      Thanks again @Gordon8 for your response, I'm open to trying any other suggestions that you or others may have.

      Hi @mohammednaveed, thanks for your response! The VIO is working properly and sends data to the mavlink inspector.

      The main issue I'm having is that the drone won't arm because of a gps error. Other than that, everything else seems to be working correctly. Any advice on troubleshooting the gps error would be greatly appreciated.

      Thanks,

      Karl

    • GPS Denied Environment with VIO

      Hello,

      I have a Flight Deck controlling motors through the ModalAI ESC (v2). The drone is updated with firmware v1.11.3-0.0.5 and has parameters loaded from this repository as follows:

      platforms --> v1.11 --> m500_4s_config

      helpers --> m500 --> collision_prevention, ekf2_indoor_vio, and enable_uart_esc

      I am able to actuate the motors through voxl-px4-shell, but cannot arm the drone because of a GPS error.

      My goal is to get the drone flying indoors with VIO position mode.

      Is there a way to diagnose the GPS error to determine the source of the problem?

      Here's the output from nsh> gps status.

    • Voxl Esc v2 with Flight Deck

      Hello All,

      I have a Voxl Esc v2 that I am trying to use along with the flight deck. The documentation says that a developer firmware is needed to get this setup operational. Where do I access this new firmware? I have not found the standard firmware (booted through QGC) to control the motors when connected to this speed controller.

      Thanks in advance!

      Karl
