@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?
-
@tom Yes, the QGC has auto-connect over UDP enabled.

@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.

@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-px4after modifying the config file.The setting of our QGC is:
.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 journalctl -u voxl-mavlink-server -
-
@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 adb rebootThe services seem to be having issue in this current state based off of the WARNING

Default is qvio * * en_send_vio_to_qgc: * Enable sending of VIO odometry messages to QGC for debug. * Note PX4 also sends odometry messages to QGC, so look for * the messages in mavlink-inspector marked as from component 197 * * en_reset_vio_if_initialized_inverted: * For VIO algorithms like qVIO that can initialize in any orientation * and output their estimate of the gravity vector, we suggest leaving * this enabled to allow vvpx4 to automatically send the reset signal * back to the VIO pipe if VIO was initialized upside-down or sufficiently * off-level. Helpful if the user powers on a drone while carrying it to * the flight area and VIO starts too early. * * vio_warmup_s: * Wait this for this amount of time of having good VIO data before * actually starting to send to PX4. This helps stop EKF2 getting * confused if VIO flickers in and out while struggling to init. * Set to 0 to disable the feature. * * send_odom_while_failed: * Off by default. Reserved for the future when PX4 supports quality field * * ############################################################################## * ## APQ8096-only Features * ############################################################################## * * en_set_clock_from_gps: * Enable setting the VOXL system time to GPS time if no NTP server can be * reached via network to set the time. * * en_force_onboard_mav1_mode: * Force PX4 to use onboard mode for mavlink 1 channel which is the channel * apq8096 (VOXL1) uses to communicate UART Mavlink with PX4. Not applicable * to qrb5165-based platforms. Sets the MAV1_MODE PX4 param. * * en_reset_px4_on_error: * Trigger a reboot of PX4 one some of PX4's unrecoverable errors, * Not applicable to qrb5165 * Yaw estimate error & High Accelerometer Bias and both detected * * ############################################################################## * ## Misc Features * ############################################################################## * * horizon_cal_tolerance: * Allowable standard deviation in roll/pitch values to consider the drone * stable enough in flight to do a PX4 horizon calibration. Default is 0.45, * you can increase this slightly if flying in a small indoor area or with * a drone that does not hold still very well. * See https://docs.modalai.com/calibrate-px4-horizon/ * * ############################################################################## * ## offboard mode config * ############################################################################## * * offboard_mode: The following are valid strings * off: VVPX4 will not send any offboard commands to PX4 * figure_eight: Default value, VVPX4 commands PX4 to fly a figure 8 path * follow_tag: Drone will follow an apriltag around. Very dangerous, not * recommended for customer use, for ModalAI R&D only. * trajectory: VVPX4 receives polynomial trajectories by pipe and commands * PX4 to follow the trajectory path. Still in development. * * follow_tag_id: * Apriltag ID to follow in follow_tag mode * * figure_eight_move_home: * Enable by default, resets the center of the figure 8 path to wherever * 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 * has drifted significantly. * * robot_radius: * Robot radius to use when checking collisions within the trajectory monitor. * The trajectory monitor is only active when in trajectory mode * * collision_sampling_dt: * The time step to sample along the polynomials by when checking for collisions * in the collision monitor. * * max_lookahead_distance: * Maximum distance to look along the trajectory. Sensor data further out can be * unrealiable so keeping this value small reduces false positives * * ############################################################################## * ## Fixed Frame Tag Relocalization * ############################################################################## * * en_tag_fixed_frame: * Enable fixed frame relocalization via voa_inputs. * See: https://docs.modalai.com/voxl-vision-px4-apriltag-relocalization/ * * fixed_frame_filter_len: * Length of the moving average filter to use for smooth relocalization * when a tag is detected. Default is 5, a longer filter will result in * smoother behavior when a new tag comes into view. Set to 1 to do no * filtering at all and assume every tag detection is accurate. * * en_transform_mavlink_pos_setpoints_from_fixed_frame: * When enabled, mavlink position_target_local_ned_t commands received on * via UDP will be assumed to be in fixed frame and are then transformed * to local frame before being sent to PX4. This allows offboard mode * position commands from MAVROS/MAVSDK to be in fixed frame relative to * voa_inputs even though PX4/EKF2 operates in local frame relative to where * VIO initialized. * * ############################################################################## * ## Collision Prevention (VOA) * ## Settings for configuring data sent to PX4 for Collision Prevention * ############################################################################## * * en_voa: * Enable processing of DFS and TOF data to be sent to PX4 as mavlink * obstacle_distance messages for collision prevention in position mode. * * en_send_voa_to_qgc: * Enable sending of VOA obstacle_distance messages to QGC for debug. * * voa_lower_bound_m & voa_upper_bound_m: * VOA ignores obstacles above and below the upper and lower bounds. * Remember, Z points downwards in body and NED frames, so the lower bound * is a positive number, and the upper bound is a negative number. * Defaults are lower: 0.15 upper: -0.15 Units are in meters. * * voa_memory_s: * number of seconds to keep track of sensor readings for VOA * default: 1.0 * * voa_inputs: * Array of pipes to subscribe to for use with VOA, up to 10 supported * Each entry has 4 fields: * * enabled: true or false, it's safe to leave this enabled when the pipe is missing * type: can be point_cloud, tof, or rangefinder * input_pipe: pipe name, e.g. stereo_front_pc, rangefinders, tof, etc * frame: frame of reference, should be listed in /etc/modalai/extrinsics/conf * */ { "config_file_version": 1, "qgc_ip": "172.16.0.204", * * voa_inputs: * Array of pipes to subscribe to for use with VOA, up to 10 supported * Each entry has 4 fields: * * enabled: true or false, it's safe to leave this enabled when the pipe is missing * type: can be point_cloud, tof, or rangefinder * input_pipe: pipe name, e.g. stereo_front_pc, rangefinders, tof, etc * frame: frame of reference, should be listed in /etc/modalai/extrinsics/conf * */ { "config_file_version": 1, "qgc_ip": "172.16.0.204", "en_secondary_qgc": false, "secondary_qgc_ip": "192.168.1.214", "qgc_udp_port_number": 14550, "udp_mtu": 512, "en_localhost_mavlink_udp": true, "localhost_udp_port_number": 14551, "vio_pipe": "qvio", "en_vio": true, "en_send_vio_to_qgc": false, "en_reset_vio_if_initialized_inverted": true, "vio_warmup_s": 3, "send_odom_while_failed": false, "horizon_cal_tolerance": 0.5, "offboard_mode": "off", "follow_tag_id": 0, "figure_eight_move_home": true, "robot_radius": 0.300000011920929, "collision_sampling_dt": 0.1, "max_lookahead_distance": 1, "en_tag_fixed_frame": false, "fixed_frame_filter_len": 5,The

@bgaudel Apologies, the .conf was what I meant. Are you still having the same issue?
-
@tom yes, still not able to connect with
QGCThe output of
voxl-px4command is:
Does this look okay? What other settings and files should I pay attention for? -
@bgaudel
voxl-px4is already running in the background, there's no need to try to start any of the processes manually from the command line.Now that you've gone through
voxl-configure-mpa, can you try these commands again so we can get some info:journalctl -u voxl-px4 journalctl -u voxl-vision-px4 journalctl -u voxl-mavlink-server -
