      Thank you for your insight everyone,

      We have an important milestone coming up in 2 weeks so we're going to use the external flight controller until then and then resume troubleshooting this issue after that - trying all the suggestions above.

      Thanks, see you in 2 weeks!

        Hi, I have the same problem. I have VOXL 2 I/O and every time I try to take it off it wobbles and crashes. I have a quad x, I have done the ESC calibration and I have followed all the instructions. Is there any solution to this problem?

          @Chad-Sweet @xav04 I have had a chance to get our new ModalAI x T-motor F55A ESCs out of the box and plug them in. I can communicate with them over FTDI converter on my laptop, but the VOXL2 doesn't recognise them.
          There's not much troubleshooting I can do as the tutorial just says to plug it in and set the correct PX parameters. Do I remember correctly that I read somewhere the MAVLink console doesn't work on VOXL2? It certainly doesn't work on mine.
          The motors don't spin when I arm, and I'm not getting any telemetry info from them.
          I followed the tutorial for VOXL EXC V2. IS there anything special I need for the F55A?

            Hey @Patrick-Hinchey I can get on the phone with you tomorrow if easier just let me know.

            It's likely the baud rate on the VOXL2 side that needs to be updated. There's a param UART_ESC_BAUD that by default is 250kbit

            https://github.com/modalai/px4-firmware/blob/voxl-dev/src/drivers/uart_esc/modalai_esc/modalai_esc_params.c#L57

            I believe the default baud on this F55A config is going to be 2Mbit (2000000 as the param).

            When you mentioned you are talkin' to them over FTDI, is this through the voxl-esc python tools?

            As for the MAVLink console, we don't have the plumbing going for some of the commands over the UDP link from QGC to VOXL2.

            That said, you can get to the nuttx like shell via command line if you SSH onto target or adb (captured here, as a work around )

              @modaltb Sorry for not replying. Is there an option to set up email notifications?
              Yep I was talking to the ESC with voxl-esc python tools. And I believe it was indeed at 2Mbaud.

              We've decided to use the FlightCore V2 as the flight controller going forward, with VOXL2 acting only as companion computer. We may revisit this sometime in the future as a weight-reduction exercise, but not any time soon

                OK thanks for the info, we are still looking at the main issue at hand in this thread still.... it's slow progress right now, but we will update here when I have positive movement to share.
