      After running:

      roslaunch voxl_mpa_to_ros voxl_mpa_to_ros.launch 
      
      

      on the VOXL with the latest stable version of voxl-tflite-server running (v0.1.6), I noticed that the tflite pipe would disconnect and reconnect after about 5-10 minutes.

      Here is an output of that occuring:

      Found new interface: tflite
      Found new interface: tracking
      Found new interface: cpu_monitor
      Found new interface: imu0
      Found new interface: imu1
      Found new interface: vvpx4_gps_raw_int
      Found new interface: vvpx4_mavlink_io
      Found new interface: vvpx4_sys_status

      Found new interface: vvpx4_body_wrt_fixed
      Found new interface: vvpx4_body_wrt_local
      Found new interface: qvio_extended
      Found new interface: vvpx4_shell
      Found new interface: qvio
      Interface: tflite's data pipe disconnected, closing until it returns

      Interface: tflite's data pipe disconnected, closing until it returns
      Found pipe for interface: tflite, now advertising
      
      

      When this happens all of the cameras on voxl-portal are no longer viewable. I can select them but no image shows up. Even if I restart voxl-portal or the voxl-tflite server the cameras don't show up in voxl-portal. The only fix to this is to restart the voxl entirely.

      I then tested to see if this happened without voxl-mpa-to-ros running. Unfortunately, the same error still occurs. After about 5-10 minutes the cameras are no longer viewable in voxl-portal with the only fix being to reboot the voxl.

        @colerose please see the latest version v0.1.8 on dev or stable. This version also includes a new output pipe (tflite_data) by default that will publish metadata about detections, in the form of:

        typedef struct object_detection_msg {
            int64_t timestamp_ns;
            uint32_t class_id;
            char class_name[64];
            float class_confidence;
            float detection_confidence;
            float x_min;
            float y_min;
            float x_max;
            float y_max;
        } __attribute__((packed)) object_detection_msg;
        
        typedef struct detections_array {
            int32_t num_detections;
            object_detection_msg detections[64];
        } __attribute__((packed)) detections_array;

          @Matt-Turi thanks for letting me know! Does this new version crash less often? Also, will the output pipe work with voxl_mpa_to_ros?

            @colerose Yes, the new version fixes this issue and should no longer be a problem.

            The new output pipe is not compatible with voxl_mpa_to_ros yet, but it will be added in very soon!

              @Matt-Turi Can you please let us know if voxl_mpa_to_ros is compatible with the new output pipe? Thanks.

                @Wei-Cui @colerose The dev latest version of voxl_mpa_to_ros is now compatible with the new output pipe. See the latest package on our opkg repo titled voxl-nodes_0.2.2_202112212238.ipk or public gitlab.
