    @bgaudel Yep, that shouldn't be an issue

    @tom Thank you so much. After reflashing the drone and enabling the required services, we attempted to establish a connection with the QGC. However, we encountered an issue as the connection could not be established.

    These are the activated services in our drone.

    we used voxl-configure-vision-px4 to connect drone with QGC

    How we can establish the connection between QGC and Drone?

      @bgaudel Are you able to ping the drone from the ground station and vice-versa?

        @tom Yes I am able to ping the drone from GS and vice versa shown in the image below.

        This one is ping my PC from drone:

          @bgaudel Have you been able to connect to QGC on this PC in the past? I'm wondering if there is some firewall preventing the traffic

            @tom Indeed, I have previously utilized the same computer without any issues, and the connection was established successfully. It is perplexing since I have not implemented any firewall restrictions on the PC. I am uncertain about the underlying cause of this connectivity problem.

              @bgaudel Does QGC have auto-connect over UDP enabled?

                Is there any specific configuration or installation that we need to do for px4 or QGC after installing the VOXL SDK image on a rb5 drone?

                  Is there any specific configuration or installation that we need to do for px4 or QGC after installing the VOXL SDK image on a rb5 drone?

                  @bgaudel What does your voxl-vision-px4 config file look like? cat /etc/modalai/voxl-vision-px4.conf?

                  I'm seeing qgc_ip: NULL, which may be the issue

                    @tom we tried different settings. The following is the IP setup that we have on the LAN network using a router. "qgc_ip": "172.16.0.203", is my computer IP, and the drone IP is 172.16.0.75". Also, the ping test works back and forth.

                     *         Controller by providing the IP address of your ground station computer
                     *         in the “qgc_ip” field of the config file. This field is also configured
                     *         as one of the first questions in the configuration wizard.
                     *         If you wish to rely on QGC to initiate the connection to VOXL you can
                     *         leave this field as-is, blank, or “NULL”. Mavlink data is sent to this
                     *         IP on port 14550 by default, but this can be changed with the
                     *         qgc_udp_port_number config value.

                     *         connections can be made as long as they are initialized by the other device.
                     *

                     *         Max size of UDP packet to send to QGC. Multiple mavlink messages will be
                     *         combined into one UDP packet to reduce network traffic. Set this to 0 to
                     *         send one UDP packet for every mavlink message. Default is 512 which
                     *         allows several mavlink messages per UDP packet.
                     *

                     *         enabled. This is set to true by default. This will allow one local process
                     *         to communicate with PX4 via port 14551 by default, NOT 14550 which is
                     *         reserved for connections outside the board. These separation prevents
                     *         conflicts between the two sockets. Both MAVROS and MAVSDK can be

                     *         the drone is when flipped into offboard mode. When disabled, the drone
                     *         will quickly fly back to the XYZ point 0,0,-1.5 in VIO frame before
                     *         starting the figure 8. Disabling this feature can be dangerous if VIO

                      @tom we tried different settings. The following is the IP setup that we have on the LAN network using a router. "qgc_ip": "172.16.0.203", is my computer IP, and the drone IP is 172.16.0.75". Also, the ping test works back and forth.

                       *                 recommended for customer use, for ModalAI R&D only.

                       *         the drone is when flipped into offboard mode. When disabled, the drone
                       *         will quickly fly back to the XYZ point 0,0,-1.5 in VIO frame before
                       *         starting the figure 8. Disabling this feature can be dangerous if VIO

                       *         when a tag is detected. Default is 5, a longer filter will result in

                      @bgaudel After modifying the conf file, are you restarting voxl-vision-px4 with systemctl restart voxl-vision-px4?

                        @bgaudel After modifying the conf file, are you restarting voxl-vision-px4 with systemctl restart voxl-vision-px4?

                        @tom yes we did systemctl restart voxl-vision-px4 after modifying the config file.

                        The setting of our QGC is:

                        c1430128-5601-46a5-8b18-c01cb37d69b6-image.png.

                        Still not able to connect with QGC. We also tried the same thing on the two different PC. Are there any settings or configurations that we especially need to take care of?

                          @bgaudel It seems as though you have all the configs setup correctly, can you post the status of the following services:

                          systemctl status voxl-px4
                          systemctl status voxl-vision-px4
                          systemctl status voxl-mavlink-server

                              @bijay-gaudel How about:

                              journalctl -u voxl-px4
                              journalctl -u voxl-vision-px4

                                  @bijay-gaudel Let's reset all of the services to their default / working state for RB5, can you run the following:

                                  # configure services to defaults
                                  voxl-configure-mpa -f rb5-flight
                                  
                                  # modify /etc/modalai/voxl-vision-px4 with your correct qgc_ip
                                  vi  /etc/modalai/voxl-vision-px4
                                  
                                  # reboot rb5

                                  The services seem to be having issue in this current state based off of the WARNING

                                        @bgaudel Apologies, the .conf was what I meant. Are you still having the same issue?

                                          @tom yes, still not able to connect with QGC

                                          The output of voxl-px4 command is:

                                          00caa24f-a0e0-4580-b12e-ea176577e680-image.png
                                          Does this look okay? What other settings and files should I pay attention for?
