    • RE: Unable to setup VIO on external flight controller

      @Chad-Sweet After about a week of debugging, turns out external flight controller only works on the older version of firmware, VOXL2 Platform 0.9.
      Instead of the newest one VOXL2 Platform 1.3.1-0.8 or VOXL2 Platform 1.2.1-0.7.
      PLEASE state it in your documentation!
      I initially need to install the 1.2 version since I need to communicate with VOXL2 IO
      Thank you

    • Unable to initiate MAVlink through UART on VOXL2 ttyHS1

      Trying to get VIO work on external flight controller.
      Followed the guide on this page https://docs.modalai.com/voxl2-external-flight-controller/
      Have checked with Minicom that ttyHS1 is working, and signals can be detected through oscilloscope, both rx and tx.
      Although mavlink server is running in voxl2, there is no data coming out of ttyHS1.
      I have made sure that "en_send_vio_to_qgc" is set to true and MAVlink data is received through QGC.
      I have also disabled px4.

      In the documentation, there is this line when typing voxl-mavlink-server
      70be130e-86e9-4d53-8389-8e1b5aa972dd-image.png
      why is it not appearing in my VOXL2 with M0125?
      Have tried adding "external_fc": true, but it doesn't work
      Have checked it with an oscilloscope and everything is wired correctly.
      Any help is appreciated

    • RE: Unable to setup VIO on external flight controller

      @Chad-Sweet said in Unable to setup VIO on external flight controller:

      EKF2_MAG_TYPE 5

      I have set both parameters.
      I have also set EKF2_HGT_MODE to vision.
      And it's still not working 😞

      In fact, LOCAL_POSITION_NED is nowhere to be found in mavlink, only POSITION_TARGET_LOCAL_NED, are they the same?
      I am currently using PX4 1.13.3
      Thank you for your swift reply~

    • Unable to setup VIO on external flight controller

      Unable to setup VIO on external flight controller.
      I have set up and received Mavlink odometry message from Voxl 2.
      I have also set up the EKF2_AID_MASK value to 280.
      But I am still unable to switch to position mode with the error code "check for position estimate"

      POSITION_TARGET_LOCAL_NED xyz values are nan.
      What am I missing?
      Thank you~

    • RE: Camera Calibrator overlay ERROR

      Found the problem
      it's supposed to be:
      voxl-calibrate-camera stereo_front
      or
      voxl-calibrate-camera stereo_rear
      instead of what the documentation said:
      voxl-calibrate-camera stereo
      Everytime I followed the guide, it will brick voxl2 and I have to reset it all over again
      Poor guide!!!!!!!!!!!

    • Camera Calibrator overlay ERROR

      I have just succeeded in calibrating the tracking camera.
      But when I tried to calibrate the stereo camera, nothing showed up in VOXL portal
      I have tried restarting VOXL2 but nothing works
