      Hello,
      I have a drone using a 5v VOXL ESC Mini 4-in-1 with Built-in Power Module with the voxl2 and I have run into an issue where after some use the ESC are not detected anymore by the voxl2. Sometimes, the I can run the commands described in https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-tools/calibration.md to manually spin but I can no longer fly through QGC and the blue status light does not blink anymore. After some time though I could not even run the commands on the voxl either and I get a notice that no ESC is detected. The blue light still comes on and the voxl is powered through it so power is for sure going through. Anything to try or test to diagnose or get these working? Nothing should have changed in between them working and not working

        @mkriesel , you should try to communicate with the ESC from a linux PC using a serial to usb adapter and voxl-esc tools. This will remove VOXL2 from the loop and allow you to test the ESC independently.

        It seems there may be some intermittent issue, since you are saying that sometimes you are able to manually spin. what about voxl-esc-scan.py ? Check UART cable?

          @mkriesel This cable will help if you do not already have one: https://docs.modalai.com/cable-datasheets/#mcbl-00091
          Quick Edit/add: I just noticed our team never had these listed on our shopify site, so they are adding them soon! Thanks!

            @Vinny Part of the issue is it doesn't see to be detected/work on boot but when I use the commands it does work, sometimes it doesn't work at all even with the commands but at the moment it doesn't work on boot at all. Is this an issue with the cable do you think? I ask because there will be no difference between the scenarios and trying the same setup (cables and voxl) with a different ESC seems to work so to me it seems like I somehow broke the esc, but I'm not sure how.

              Hi @mkriesel
              My comment was in regards to Alex's suggestion such that if you use an independent UART cable, you can ascertain whether the issue is with the ESC or the VOXL 2. MCBL-00091 will allow you to do that from a host PC as Alex mentioned.
              It is live now on our shopify site if that will help.
