    @James-Strawson Thanks for the reply! Now I am facing a new issue though, after I swapped the camera ids the calibration of the extrinsics is asking me to move the checkboard in only three locations instead of four, as a result the reprojection error keeps being high, is this a bug? Result of the new extrinsics: Calibrating Extrinsics 4 frames will be processed R [-0.2178154138909582, 0.5612314553199155, 0.7984833742984259; 0.6516188344157804, -0.5254512170251917, 0.5470776116433248; 0.7266012249550162, 0.6394687420712871, -0.2512576124371861] T [-0.5933205685053882; -0.3699353785761611; 0.8991646361380521] Re-projection error reported by stereoCalibrate: 71.628572 Detected horizontal stereo pair Distance between cameras: 0.5933 Extrinsics Calibration Failed exceeded allowable max reprojection error: 0.5 voxl-camer-server with ids already swapped, the stereo in question is stereo_rear, { "version": 0.1, "cameras": [{ "name": "tracking", "enabled": true, "frame_rate": 30, "type": "ov7251", "camera_id": 2, "ae_desired_msv": 60, "ae_filter_alpha": 0.600000023841858, "ae_ignore_fraction": 0.20000000298023224, "ae_slope": 0.05000000074505806, "ae_exposure_period": 1, "ae_gain_period": 1 }, { "name": "hires", "enabled": true, "frame_rate": 30, "type": "imx214", "camera_id": 3, "preview_width": 640, "preview_height": 480, "snapshot_width": 3840, "snapshot_height": 2160 }, { "name": "stereo_front", "enabled": true, "frame_rate": 30, "type": "ov7251", "camera_id": 0, "camera_id_second": 1, "independent_exposure": false, "ae_desired_msv": 60, "ae_filter_alpha": 0.600000023841858, "ae_ignore_fraction": 0.20000000298023224, "ae_slope": 0.05000000074505806, "ae_exposure_period": 1, "ae_gain_period": 1 }, { "name": "stereo_rear", "enabled": true, "frame_rate": 30, "type": "ov7251", "camera_id": 4, "camera_id_second": 5, "independent_exposure": false, "ae_desired_msv": 60, "ae_filter_alpha": 0.600000023841858, "ae_ignore_fraction": 0.20000000298023224, "ae_slope": 0.05000000074505806, "ae_exposure_period": 1, "ae_gain_period": 1 }] }

    @Moderator Besides extracting out the libraries and running them on an ARM based computer, how else can we simulate VOXL's behaviour? From what I understand for HITL, we are only interfacing with voxl-px4 but not other services like voxl-vision-hub.

    We're not really sure how we can help you. What are you trying to achieve? Is there a specific device you are trying to work with? The kernel should work as other Linux kernels, so if you have made this change elsewhere the steps should be similar

    @José-Quintanilla Was this solved? If yes, how? I'm having a similar issue where the drone is constantly drifting towards its right/left (Mostly right, but sometimes left too)

    @SMRazaRizvi A compass (magnetometer) and a GPS receiver are two completely separate sensors. GPS reception won't affect the compass.

    @Moderator That makes way more sense, thank you for the clarification As far as I could understand, there is no text saying that the .conf for the extrinsics is only used for the voxl-mapper on the modalai.docs, I think that is where my confusion came from

    @Wei-Cui-0 Sure, it's just http traffic. You would have to parse on your own of course and reverse engineer from the source code here The image streams are just standard mjpeg though, so those should be easy to grab

    @Jagatpreet-Nir Were you able to find a resolution to this? We are also experiencing the exact same issue has you. IMU is coming in around 220 Hz and there is alot of dropped data and timestamp jumping. Check out this sample graph below. [image: 1692835321669-imu-timestamp.png]

    The website was incorrect, it has been fixed There is not a version of Startling pet support Doodle labs radios You may be able to design an adapter yourself, but it is not clear. The drone would fly appropriately with that much additional weight
