    @ravi Can you stop the system service for voxl-mavlink-server (e.g. systemctl stop voxl-mavlink-server) and run it from the command line instead with the -z option to see all message traffic? You should see something like this:

    For testing, I changed the UART port to 2 and then change to port 12.
    stopped service and ran "voxl-mavlink-server -z"
    and got the following errors.

    ![68d1045c-eaa7-46ee-b0de-b313bee851cb-1000019409.jpeg](/assets/uploads/files/1762187345269-68d1045c-eaa7-46ee-b0de-b313bee851cb-1000019409.jpeg) code_text
    

    Then rebooted the VOXl2 and tried again, and got this log. But no MAVLink connection with FCv2. using J1 of FCv2 to connect with J18 of VOXL2.

        mavlink-server status issue seems random.

        I stopped the service and changed the baud rate, and ran app from the terminal "voxl-mavlink-server"

        Seems MAVLink connection established. and getting an AP heart rate at 0.3Hz.

        Then I tried the same with mavlink service.
        I terminated it running process for the mavlik-server.
        They started the MAVLink service. and checked status and not starting.

          @Eric-Katzfey

          I am testing with J18(VOXl2) and J1(TELEM1) port.
          Seems SLPI is throwing a lot of errors in demsg.
          and @115200 buadrate.

          • MAVLink connections are getting lost in a few minutes.
            and getting rx loss of 124% on FCv2 QGC.

          Can you let me know if the J18 DSP port is buggy or how to fix these errors?
          After a few minutes or a few restarts of VOXl-mavlink-server. it stops working and shows an error and exits

            @Eric-Katzfey

            I am testing with J18(VOXl2) and J1(TELEM1) port.
            Seems SLPI is throwing a lot of errors in demsg.
            and @115200 buadrate.

            • MAVLink connections are getting lost in a few minutes.
              and getting rx loss of 124% on FCv2 QGC.

            Can you let me know if the J18 DSP port is buggy or how to fix these errors?
            After a few minutes or a few restarts of VOXl-mavlink-server. it stops working and shows an error and exits

            @ravi J18 should work. Let's try this one step at a time and see if we can figure out where the issue is. Start by disabling the voxl-mavlink-server, voxl-px4, etc. services and power cycle the VOXL 2. With port set to 12 and baudrate at 57600 does voxl-mavlink-server -z show connection with autopilot? If so, does it stay connected? And can you connect GCS? If all of that works fine, power cycle the VOXL 2 and just make sure that it reliably works. Let me know how all that goes before we move to the next step.

              @Eric-Katzfey

              I am testing with J18(VOXl2) and J1(TELEM1) port.
              Seems SLPI is throwing a lot of errors in demsg.
              and @115200 buadrate.

              • MAVLink connections are getting lost in a few minutes.
                and getting rx loss of 124% on FCv2 QGC.

              Can you let me know if the J18 DSP port is buggy or how to fix these errors?
              After a few minutes or a few restarts of VOXl-mavlink-server. it stops working and shows an error and exits

              @ravi Keep in mind you must power cycle the VOXL 2 between each thing you do because the DSP (SLPI) won't cleanly shut down and if you try to start voal-mavlink-server again it will fail.

                @Eric-Katzfey

                I tested J18(VOXl2) SDK 1.5 and J1(FCv2) firmware V1.15.2.
                VOXL2 is connected with FCv2.
                FCv2 connected with QGC.

                I rebooted VOXL2. But after a few minutes, MAVLink connection broke.

                I will test J18 later.

                Now, to move forward. using J9 for 5G modem and connected with J1 FCv2.
                Connection seems stable. Now the connection is lost.

                But now the major issue is that RX loss is 124%.
                I disabled messages 331,84 and configured 330 @ 10Hz.

                Still, I am experiencing a 21.3% Rx loss.
                The only messages visible is Heatbeat(0) and Obstacle_distance(330).

                I did check. How many messages does FCv2 lose?
                seems to be successfully receiving only 10-11 messages per second
                and losing 254 messages per second.
                So, actually getting only <5% messages successfully.

                  @Eric-Katzfey

                  I tested J18(VOXl2) SDK 1.5 and J1(FCv2) firmware V1.15.2.
                  VOXL2 is connected with FCv2.
                  FCv2 connected with QGC.

                  I rebooted VOXL2. But after a few minutes, MAVLink connection broke.

                  I will test J18 later.

                  Now, to move forward. using J9 for 5G modem and connected with J1 FCv2.
                  Connection seems stable. Now the connection is lost.

                  But now the major issue is that RX loss is 124%.
                  I disabled messages 331,84 and configured 330 @ 10Hz.

                  Still, I am experiencing a 21.3% Rx loss.
                  The only messages visible is Heatbeat(0) and Obstacle_distance(330).

                  I did check. How many messages does FCv2 lose?
                  seems to be successfully receiving only 10-11 messages per second
                  and losing 254 messages per second.
                  So, actually getting only <5% messages successfully.

                  @ravi It's acting like you have a mismatch in baudrate settings for the UARTs. Try setting the baudrate to 115200 for port 12 in /etc/modalai/voxl-mavlink-server.conf. In order to setup the FCv2 connect to QGC with USB and set SER_TEL1_BAUD to 115200 8N1, then reboot. Make sure you are connected to the TELEM1 connector on FCv2 and J18 on VOXL 2.

                    As said,
                    I will test J18 later.

                    Currently, I am using J9 of a 5G modem and connected with J1 of FCv2.

                    Connection seems stable. using a 921600 baud rate with port 2.
                    The major issue is RX loss.

                    seeing 95% message loss, as I explained in an earlier post.

                    below is mavlink status visible on QGC mavlink console:

                    As above, the RX loss showing is 21.3% which is huge.
                    It is in normal mode. If I change the mavling mode to onboard, it is an 83% loss. and with vision hub odomatry, distance massages it is getting worst like 125%.

                    Now. This Rx loss does not match the number.

                          sysid:  1, compid:197, Total: 7820 (lost: 180596)
                    

                    As per this MAVLink status, the total successfully received messages are 7820, and the lost are 180596.
                    So, actual loss is (180596/(7820+180596)) = 95.8%.
                    And it is showing only 21.3%.

                    So, MAVLink is working between VOXl2 and FCv2. Currently using UART port 2 of VOXl2, not 12. I will debug it later. Once setup is complete.

                      As per this MAVLink status, the total successfully received messages are 7820, and the lost are 180596.
                      So, actual loss is (180596/(7820+180596)) = 95.8%.
                      And it is showing only 21.3%.

                      So, MAVLink is working between VOXl2 and FCv2. Currently using UART port 2 of VOXl2, not 12. I will debug it later. Once setup is complete.

                        As said,
                        I will test J18 later.

                        Currently, I am using J9 of a 5G modem and connected with J1 of FCv2.

                        Connection seems stable. using a 921600 baud rate with port 2.
                        The major issue is RX loss.

                        seeing 95% message loss, as I explained in an earlier post.

                        below is mavlink status visible on QGC mavlink console:

                        nsh> mavlink status
                        
                        instance #0:

                              rx loss: 21.3%

                            Forwarding: On
                            MAVLink version: 2
                            transport protocol: serial (/dev/ttyS6 @921600)
                        
                        

                        As above, the RX loss showing is 21.3% which is huge.
                        It is in normal mode. If I change the mavling mode to onboard, it is an 83% loss. and with vision hub odomatry, distance massages it is getting worst like 125%.

                        Now. This Rx loss does not match the number.

                              sysid:  1, compid:197, Total: 7820 (lost: 180596)
                        

                        As per this MAVLink status, the total successfully received messages are 7820, and the lost are 180596.
                        So, actual loss is (180596/(7820+180596)) = 95.8%.
                        And it is showing only 21.3%.

                        So, MAVLink is working between VOXl2 and FCv2. Currently using UART port 2 of VOXl2, not 12. I will debug it later. Once setup is complete.

                        @ravi I'm suspecting you have a bad cable or the cable is subject to some interference. Can you try this on a benchtop with just a VOXL 2 and an FC v2 and no other components? Is it currently integrated into a custom drone? Can you look at the signal quality on the TX and RX UART lines with an oscilloscope?
