    @Jetson-Nano , since you are probably using a custom motor and propeller you should:

    • first of all, update the ESC firmware to the latest
    • calibrate the ESC for the motor/propeller and upload params
    • update min and max rpm params in PX4 because they are used to scale the control output
    • set the correct motor mapping and direction in px4 params
    • i also recommend updating the baud rate to at least 921600 (or 1M). We are using 2Mbit for all latest ESC configs now. This reduces latency and ensures that you don't have ESC packet drops (depending on the update rate of your flight control loop)

    In order to perform the updates and tuning, you will need to use voxl-esc tools. Please see the following page for more info: https://docs.modalai.com/voxl-escs/faq/

      hey @Alex-Kushleyev
      I am facing the same issue again, the ESC is not initialising when connected through fc v2 , i have followed all the suggestions you mentioned earlier. the FC as well as VOXL 2 is powered through ESC.

        @Jetson-Nano ,

        The primary causes of ESC not being detected by the FC (aside from hardware / wiring issues) is using incorrect UART port or incorrect baud rate. So you should make sure the ESC is running the latest firmware, double check the params that you want to use on the ESC (for your motor / prop) and you can also set the ESC baud rate in the ESC params. You should set up your ESC (using voxl-esc tools) before plugging it into your FC, so that you know exactly what your ESC is set up to do and then you just need to match your PX4 params to what you set in the ESC (baud rate, rpm limits, and use correct UART port).

          @Alex-Kushleyev Thank you for reverting, I didnt change anything with respect to the fc or ESC, the firmware is the same.
          could you help me with understanding why it was working earlier , it is not now.
          The firmware of the FC is voxl-fpv-dev version, and when i tried to build again it is giving error, and not building.
          I still dont know whether the issue is with respect to FC firmware or ESC

            @Jetson-Nano , please confirm the ESC is working by using a usb to serial connection directly to the esc and voxl-esc Python tools on a Linux PC or VM.

            You can run simple commands to detect the esc and perform spin tests if needed, this is all documented.

            If the esc is ok, then you will need to double check the FC v2 setup.

              Hey @Alex-Kushleyev , for the same setup I mentioned above my esc is not starting by default, while I run voxl_esc start in mavlink console, it starts and works.
              what could be the reason for such behaviour. Please could you help me out

                @Jetson-Nano , this is likely related to the fact that the FC starts quicker than the ESC bootloader's 1s wait time. We discussed this before.

                So if you are saying that delaying the start of voxl_esc driver in px4 on your FC solves the problem, then the issue is exactly that.

                Please delay the start of the voxl_esc driver in your px4 start-up script, for example you can see it at the bottom of the script here : https://github.com/modalai/px4-firmware/blob/bugfix-fpv-rev0-airframe/boards/modalai/fc-v2/init/rc.board_sensors

                if param greater VOXL_ESC_CONFIG 0
                then
                	usleep 1500000
                	voxl_esc start
                fi

                  @Alex-Kushleyev I have already tried it, It was working fine earlier. since past 2 days the behaviour has changed, I have verified everything else and nothing else could be a reason for such behaviour , I even played around with delay to verify it, still the same issue.
                  please excuse me for repeating the questions but is there any other reason that can cause this issue.

                    @Jetson-Nano ,

                    Thank you for clarifying. Unfortunately, since I don't know what you changed between the working and non-working condition, it is hard to help. Also, since you are indicating that the ESC is responding if you manually start the esc driver, then the ESC itself should still be functional.

                    Please try to backtrack your changes until you have a working setup again.

                        Hello guys, I am facing a new error where when I try to use Optical flow by enabling the UAVCAN in the default.px4board, since it was commented out. Whenever try to enable it and build it is giving error. I want to use CAN port on the FC v2 for Optical Flow. It would be of great help , if you could help with this or guide me.
