    The screen shot in earlier post today shows running “voxl-esc” which is a wrapper for the python tools, sometimes it is easier just to use python tools directly, but make sure they are latest version. the version in /usr/share/modalai is probably not latest. Normally you dont need to update the tools but if something is not working as expected, it is good to try the latest.

      We verified PX4 was not running.

      systemctl stop voxl-px4

        No worries. We also verified if the issue was with the particular param file and ran the command to upload a different one. No luck with that and we still receive the same error (Bus 12, ESC not detected, etc)

          Can you please try voxl-esc tools from dev branch on github? Instead of /usr/share/modalai/voxl-esc-tools

            Also, which SDK are you using? i am surprised to see this issue.

            Also, can you please double check the ESC bootup sequence:

            • apply power
            • 4 blue leds flash quickly for 1 second, then turn off
            • 4 blue leds blink twice
            • motor makes a quick chirp (three tones based on the latest params that provided)

                  One more suggestion, it often helps to use a direct connection between the ESC and your linux PC and run the voxl-esc tools there. This way you can see the plots instantly during testing and also if there are some issues with communication to the ESC, you can always connect it to the PC and check the ESC that way.

                  Do you have a USB to serial adapter cable that plugs into the ESC <-> PC ?

                        @rdjarvis , ok great. Lets take a step back and just make sure you can talk to the ESC from the PC.

                        I will test SDK 1.2.0 to make sure it works fine with voxl-esc tools with my esc.

                              @Alexander-Saunders , thank you for confirming. I see that you are using SDK 1.2.0, which is very recent, so it already has (almost) the latest voxl-esc tools.

                              I am in the process of testing the tools on voxl2 using SDK 1.2.0, please try to connect to your PC directly and this should properly detect your ESC.

                                  @rdjarvis,

                                  What do you mean "ssh'd into Linux PC" ?

                                  I am suggesting to connect the ESC to a standalone Linux PC and run the voxl-esc-scan.py on the linux PC (not on VOXL2).

                                  Just wanted to clarify..

                                  I tested the SDK 1.2.0 and the tools are working fine, it seems.

                                    On the Linux PC we are directly connected to 4 pin JST on ESC to USB.

                                    I ssh'd into VOXL2 from the Linux PC terminal.

                                    I ran voxl-esc-scan.py in VOXL2 (same results) No ESCs detected.

                                    I ran same command in Linux terminal (not ssh'd into VOXL2) same results. No ESCs detected.

                                    This is including running same command in /usr/share/modalai/voxl-esc-tools/.voxl-esc-scan.py

                                      @rdjarvis,

                                      What do you mean "ssh'd into Linux PC" ?

                                      I am suggesting to connect the ESC to a standalone Linux PC and run the voxl-esc-scan.py on the linux PC (not on VOXL2).

                                      Just wanted to clarify..

                                      I tested the SDK 1.2.0 and the tools are working fine, it seems.

                                      @Alex-Kushleyev power is on the UAV and ESC gave proper Flashes/Tones.

                                        @rdjarvis , which serial to usb cable are you using? have you tested it with an ESC before? I am wondering if the RX/TX connections are correct and not swapped.

                                        Also, do you have any other Modalai ESC you can test just to make sure the cables are working?

                                          Both right out of the new bag.

                                          We have 2 of these. Tested both. Same results.
