    • RE: VOXL-2 Reject position control error

      @Jagatpreet-Singh-Nir

      We ship the Sentinel configured to fly outdoors using GPS positioning so that may be the reason for VIO not working for you. All you should have to do is load our EKF2 indoor/vio params. I'll drop a link to where you can find all relevant param files and helper files such as the ekf2_indoor_vio.params that you need.

      Please let us know if this helps

    • RE: ESC Power

      @Jimk_Aero

      Sorry so hear that you're still having problems. The built-in BEC shouldn't be required for basic use case. Unless you're trying to power some other on-board electronics/avionics with the BEC.

      All you should need is the "power in" to all 4 esc's from a PDB and then signal and ground from esc's to flight core J7, via the breakout board.

      Modalai's breakout board was designed for PWM signals only and works well in that regard. Also check to make sure that DSHOT_CONFIG
      is set to "disable"

      Here's some notes from our board designer to clarify.

      The primary design intent was to be used with a distribution board for power

      It is actually unsafe for these types of pin headers to have exposed voltages on them

      We wanted to prevent some customers from accidentally installing two BEC generators on these blocks which occur all the time in other hobbyist forums/kits and customers end up damaging their BEC modules.

      We apologize we did not make it clearer this is just a breakout board and not a BEC distribution block.

    • RE: ESC rail power issue

      Our PWM breakout board does not have the positive rail connected.

    • RE: Replacement motors for m500

      @Todd-Humphreys

      Hi Todd,

      I believe they are replacing them with almost identical motors but with a slightly higher KV value. If you can source those then they would be a drop in replacement.

      If you're interested in something else, then here's some that I've tested before. The only thing is you'd need to solder the 3 male 2mm bullet connectors onto each motor. Otherwise they're drop in replacements.

    • RE: Arming Issues with Controller

      @rohitpillai
      Hi,

      The drone not arming can be caused by many different things. Did QGC print out an error when trying to arm? That error will help us narrow down the problem.

      If there was no error then you could be having a problem with a bad calibration on either the Spektrum controller side or the esc side. Check that you don't have an "emergency kill switch" enabled. What airframe and esc's are you using?

      If you could send us a fresh log while this is happening and your px4 parameters that would be very helpfull.

      Thanks

    • RE: Camera Calibration

      @umlr ,

      Are your camera calibration files missing from the drone?

      If you ADB shell into the flight deck and then cd data/modalai
      Then do you see 5 ".yml" files?

    • RE: Blue LED does not flash once PX4 and VOXL boot up

      I would first test functionality of the voxl-flight in terms of being able to both ADB into the voxl and connect to QGC.

      If all goes well with that then I'd check the px4 firmware version on the flight core side and no matter what it's at currently I'd go ahead and re-flash with our latest px4 firmware which is obtainable via our downloads.

      This link should contain all information and relevant links to complete this update of the firmware.

    • RE: Unable to calibrate ESCs

      Hello,

      You shouldn't need to calibrate those esc's as long as you have "Dshot" enabled in the QGC parameters.

      The parameter you're looking for is "DSHOT_CONFIG"

      Enable the dshot speed that best fits your ESC specs and after that you'll want to verify all motor ordering and directions before flight.

      Here's a link with more information https://docs.px4.io/master/en/peripherals/dshot.html

    • RE: m500 firmware update

      Hi,

      Do you already have the new firmware downloaded? If so, power up the drone with usb connected.
      Connect to QGC and navigate to the firmware tab.

      At this point you want to power cycle the drone and when it comes back up in QGC you should see the window pop up which allows you to choose which firmware to select.

      I believe our videos will show you the rest of the process. Let me know if you run into problems.

    • RE: Not receiving VIO pose information from VOXL in QGC

      Follow this link https://gitlab.com/voxl-public/flight-core-px4/px4-parameters and you can find our px4 parameters and helper parameters files for different features.

      Under "Helpers" you'll find our "Indoor_VIO_params". Try installing that helper file on top of your existing parameters. Reboot the drone and see if that helps.
