There is a new module under development that allows you to pipe VGA (640x480) video from the hires camera at 30fps via MPA so that it can be streamed with voxl-streamer using RTSP while simultaneously saving 4k HD video at 30fps encoded as h265 into a file, preferably on the SD card on voxl. This module is now available in beta and will be officially released in upcoming releases of the voxl SDK for voxl, rb5-flight, and voxl 2. The beta package is available using wget https://storage.googleapis.com/modalai_public/modal_packages/archive/voxl-hires-server_0.0.1.ipk. It is meant for use on voxl only and is compatible with voxl platform release 3-3-0-0.5.0-a. In order to use it with voxl-camera-server, reconfigure voxl-camera-server to not use the hires camera. For example, call voxl-configure-cameras and choose option 1 Tracking + Stereo to allow voxl-camera-server to access the tracking and stereo cameras but not the hires camera. Then you can use voxl-hires-server for the hires camera. Use voxl-hires-server -h to see the available options. More documentation will be available upon official release of this new package.

@kitkatSG Yes, we have enabled most resolutions in that sensor now and are preparing a release to address this issue.

@JoeC Seems like it is an SD card issue. I was able to recreate the problem when using a SanDisk Extreme 32GB card. But when using a SanDisk Ultra 16GB card everything works fine.

Voxl uses systemd for startup. You create a "service" file to implement your desired startup action and place it in the /etc/systemd/system directory. There are lots of guides and documentation on the Internet about how to create systemd service files. You can also look at the service files already on Voxl for some examples.

There are a few steps you can take to bring up a new USB camera. First of all, the camera must be UVC compliant. The best thing to do is to test it out on a Linux PC first and verify that it works there. Some tips: 1. Use the 'lsusb' command before and after you plug the camera in to see if it is showing up. 2. If you see the device with 'lsusb', look in /dev to see if it shows up as a /dev/videox device. So, do 'ls /dev/video*' before plugging in the camera and after plugging in the camera to see if it appears. 3. If everything looks good you should be able to stream from it using voxl-streamer.

An update to UVC camera support has been started. It will increase number of supported cameras by allowing MJPEG and will increase number of supported viewers including latest QGroundControl versions. Target availability is mid-December.

@stevet Yes, that is the case. But it may not be possible without full access to the complete system image build. And it is also possible that there are dependencies on Qualcomm provided libraries that are only available as 32 bit binaries.

No, you shouldn't need anything special to see it with 'lsusb'. If you run 'dmesg -wH' and then plug in the camera do you see any messages printed? Another thing you can try is to free up the adb port by using ssh over wifi instead of adb. Then plug the camera into the adb port and see if you see it with 'lsusb'. It's possible you are seeing a power issue and the adb USB port can deal with more power.

@PawelJ Bear with us. Our subject matter experts are out on summer vacation this week.

@wilkinsaf The configuration file for voxl-streamer is documented here: https://docs.modalai.com/voxl-streamer/#configuration-file-format

@darwin-keem This can mean that you have a damaged power cable from the APM to the VOXL 2. The cables are Robotis 184-903-0081-000 Cable-4P if you don't have a spare to try.

@mawriyo Here3 GPS support is now available in voxl-px4 1.4.27 available here: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.4.27-202209272330_arm64.deb. This needs to be used with the Here3 in "i2c mode" which means opening up the unit, placing the switch in the "i2c" position, and creating a custom wiring harness to route UART and i2c lines over to VOXL 2 J19. Launch voxl-px4 with the new -h flag to enable this new support. The Here3 unit has an ak09916 magnetometer and TCA62724FMG LED controller.

@Ed-Sutter I'm speaking specifically of VOXL, not your host computer, but it's the same idea. It's the actual Linux device driver for that piece of hardware. For example: https://gitlab.com/voxl-public/system-image-build/apq8096-kernel/-/blob/main/drivers/net/usb/qmi_wwan.c#L772

@Rowin-Leemeijer In our documentation (https://docs.modalai.com/usb-to-ethernet-with-voxl/) we recommend this one: https://www.amazon.com/Apple-MC704LL-A-Ethernet-Adapter/dp/B00W7W9FK0/ref=sr_1_3?keywords=usb+to+ethernet+apple&qid=1575492214&s=electronics&sr=1-3

@Ed-Sutter The other thing you have to check is the USB vendor / device id. The Linux device drivers often have those hard coded into them for support. If those id's aren't in the driver then it won't set it up.

@xav04 Yes, the M0090 5G board does have a UART and I2C that you can use on J9.

@xav04 According to their spec http://www.holybro.com/manual/Holybro_H-RTK_F9P_GNSS_Spec.pdf it does have an ist8310 magnetometer which is supported by VOXL 2.

@Rowin-Leemeijer Which Ethernet dongle are you using?

@Ed-Sutter Oh, got it. Okay so one USB for external LTE modem and another for external camera. You can still use our LTE modem board but just don't put an LTE modem in the socket.

@Ed-Sutter I'm not sure I follow your comment. If you need to use 2 USB plug in devices and an LTE modem at the same time then why doesn't the LTE modem add-on board work for you?
