    • RE: px4 service issue

      @Eric-Katzfey
      I did. The issue is that the drone is supposed to be autonomous at the end. and I would like to avoid constantly checking whether the px4 service is alive or not.
      from my understanding the service is supposed to be alive on boot so it seems to be a bag that I would want to fix.

      @Eric-Katzfey
      never knew that there are services outside of /etc/systemd/system
      and systemctl status voxl-px4 gives disable. I will bring the full argument as soon as I have access to the machine

    • px4 service issue

      I have an issue with the px4 service where the px4 service starts at stop status on the drone boot. In my short time debugging this I looked at the body of the service and I see it requires another service to end:

      [Unit]
Description=px4
After=sscrpcd.service
Requires=sscrpcd.service

[Service]
ExecStartPre=/bin/sleep 2
ExecStart=/usr/bin/voxl-px4
Restart=on-failure

[Install]
WantedBy=multi-user.target

      but I can't find this service on the system nor can I find it online.
      Am I missing something?
      I would love some help with this.

      @Alex-Kushleyev
      sorry for the delay,
      this sounds about right.
      I'm not sure about the 15 fps but we do use raw preview only for our application and no other stream
      this is my camera conf file:

      cat /etc/modalai/voxl-camera-server.conf 
/**
 * voxl-camera-server Configuration File
 *
 * Each camera has configurations for up to 4 HAL3 streams:
 *    - `preview` stream for raw unprocessed images from CV cameras
 *    - `small_video` 720p (ish) h264/h265 compressed for fpv video streaming
 *    - `large_video` 4k (ish) h264/h265 for onboard video recording to disk
 *    - `snapshot` ISP-processed JPG snapshots that get saved to disk
 *
 * on QRB5165 platforms (VOXL2 and VOXL2 mini) you can only have 3 of the 4 enabled
 *
 * This file is generated from default values by voxl-configure-cameras.
 * Do not expect arbitrary resolutions to work, the ISP and video compression
 * pipelines only support very specific resolutions.
 *
 * The default video compression mode is cqp or Constant Quantization Parameter
 *
 *

      I will test it with the flight deck and let you know as soon as I can

      the flight-deck is a voxl2 unit (qrb chip)
      with voxl-camera-server 1.8.9 on 1.1.2 SDK
      other than that one imx412 is enough for the server to crash but let me know if you want the full config and/or driver list

    • RE: cam does not seem to be alive issue

      @Alex-Kushleyev hi
      I just stumbled upon the same bug with our voxl-flight-deck module that also refuses to downscale the fps.

      @Alex-Kushleyev
      It would take some time to do this since I found a workaround compiling the camera server from source with a small fix:
      I changed the hal3_camera_mgr.cpp
      from:
      int32_t frame_rate_rate[] = {fps,fps};
      into:
      int32_t frame_rate_rate[] = {1,30};
      I know this is hacky and will probably bite me if I try to put higher fps for low fps cameras like a tof or something but it works for now.
      I will get back to it and update.

      @Alex-Kushleyev
      I have tested different layouts with different cameras disabled and it didn't work either.
      for some reason, the voxl won't accept any other frame rate in the config file other than 30.

      @Alex-Kushleyev
      Hi, after I had to work on other projects I have finally come back to this and I managed to make the voxl read all cameras when I moved the tracking camera to j8-lower.
      now the issue I'm facing is with a frame rate reduction.
      it seems that whenever I try to change the frame rate of one of the high-res cameras the server crashes.
      this is the server log:

    • RE: CP with custom sensors

      @James-Strawson
      Thank you for the response.
      we want to use an array of 4 vl53l5cx sensors to capture data around the drone. I know that there is existing support for vl53l1cx sensors. since it is crucial to know of possible obstacles from multiple angles we need the 4x4 version.
      in this case, I have a point cloud of 64 points around the drone. so should I send those on the pointcloud pipe?

      for the few services:

    • CP with custom sensors

      Hi,
      I want to integrate collision prevention into my system.
      currently, I have a microcontroller that manages all the sensor data and is connected to the voxl2 through serial.
      now I debate two ways to implement this and I don't know that is the best approach.

      1. using mavlink directly to px4. I saw that the px4 exposes a UDP port to send mavlink msgs directly to px4. this feels sub-optimal as this bypasses the integrated VOA system and the voxel-vision-hub.
      2. make a pipe client and transform the data from the serial port to some kind of TOF sensor and publish it.
        Is the second option the way to go or is the first option viable as well?
        Furthermore, I don't see all the voxl-vision-hub pipes:
      voxl2:~$ voxl-list-pipes -t
camera_image_metadata_t
	hires_large_color
	hires_large_encoded
	hires_large_grey
	hires_small_color
	hires_small_encoded
	hires_small_grey
	hires_snapshot

cpu_stats_t
	cpu_monitor

imu_data_t
	imu_apps

imu_fft_data_t
	imu_apps_fft

mavlink_message_t
	mavlink_ap_heartbeat
	mavlink_attitude
	mavlink_from_gcs
	mavlink_gps_raw_int
	mavlink_local_position_ned
	mavlink_onboard
	mavlink_sys_status
	mavlink_to_gcs

point_cloud_metadata_t
	voa_pc_out

pose_vel_6dof_t
	vvhub_body_wrt_fixed
	vvhub_body_wrt_local

string
	gcs_ip_list

text
	horizon_cal_io

      Is this presenting all server pipes that have clients?

    • RE: custom uart usage

      @Eric-Katzfey
      Thank you for the reply
      The only board I have no for testing is:
      MCCA-M0151-1
      I use the USB portion for the wifi and see that it exposes a uart port- HS1 for the external USB board.
      I can't seem to communicate with this HS0 port as a standalone port.
      Is it only for external Flight controllers?

      I looked into this:
      https://docs.modalai.com/usb2-type-a-breakout-add-on/
      but it seems to expose the same uart I can not talk to.
      Can you please recommend me a board that won't affect the wifi capability but would add uart ports that I desperately need?

      • EDIT:
        also if push comes to shove I would appreciate sources on how to write and compile a px4 driver that reads from the uart on j19.

      Thank you and best regards,
      Gilad

    • RE: custom uart usage

      @giladWDS To specify. my sensor is connected to a microcontroller. so also I prefer UART I can do i2c(I have tried and it didn't work as well) and I can do SPI if it works better.

    • custom uart usage

      Hi,
      I wanted to add a custom sensor to my voxel-2 through j19 UART.
      now I see that this UART is reserved to RC-inputs. but even when I disabled those in /etc/modalai/voxl-px4.conf, I still can't access the port.
      I looked a bit and found this:
      https://gitlab.com/voxl-public/voxl-sdk/core-libs/libqrb5165-io/-/tree/master/python?ref_type=heads
      and tried using it with port 7.
      when I tried to write it gave me the following:
      ERROR: voxl_uart_write: Bus '17' is not initialized
      and on init, it gave:
      Sending library name request: libslpi_qrb5165_io.so
      Sending initialization request
      Received standard error event SNS_STD_ERROR_NOT_SUPPORTED
      Couldn't configure flight_controller sensor
      ERROR: fc_sensor_initialize failed
      ERROR: Failed to initialize slpi
      ERROR: Encountered error while initializing bus 17

      so it looks like it is still looking for some RC sensor.
      I guess my real question is how can I access SLPI UART as a user since I don't see them in /dev/tty*
      Thank you

      I can confirm that the ar0144 module works.
      it works if i switch to J7L and then the imx connected to J7L wont work when it is connected to J7U.
      I know the setup works because i am currently running it with the same hardware on another voxl2

      thank you for the comment, I will bring an ESD mat.

      it seems to be there.
      I also check with the latest drivers found in here:
      https://gitlab.com/voxl-public/voxl-sdk/services/voxl-camera-server/-/tree/master/misc_files/usr/share/modalai/voxl-camera-server/drivers/ar0144
      and it did not changed the behavior.

      Hi, thank you for your comment,
      I haven't cascaded the two cables.
      I am using MSU-M0084 to connect ar0144 and imx412 to J7, this is why it is probably looking longer then usual
