        For the esc tools, we were running the commands from /usr/share/modalai/voxl-esc-tools. To clarify, for the baud rate changes, do you want 2,000,000 or 20,000,000. We will try the tools again and confirm px4 is stopped via systemctl stop voxl-px4.

            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 ?

                              @Alex-Kushleyev, yes we have the USB/Serial connector.

                                @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.

                                    Also to confirm, I followed the README from dev branch to update.

                                      @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.

                                        ssh'd into Linux PC.
                                        Connected to ESC with USB to SERIAL
                                        voxl2:/usr/share/modalai/voxl-esc-tools/voxl-esc-scan.py

                                        received same error as Windows PC.

                                        No ESCs detected

                                          @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
