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.

How to stream hires camera at VGA resolution and simultaneously capture 4k30 to a file

RE: Streaming 4K video from Qualcomm RB5 drone
@kitkatSG Yes, we have enabled most resolutions in that sensor now and are preparing a release to address this issue.

RE: having trouble using docker on the sdcard
@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.

RE: Maximum I2C Clock Frequency
@Morten-Nissov 1MHz is a supported clock rate for i2c on the DSP based on what I can see in the code. But we have never tried running a device at 1MHz on i2c so it's tough to say why it wouldn't be working for you.

RE: VOXL2 I2C access from FC
@ceu-gomez PX4 on VOXL2 is composed of two separate applications. One is on the applications processor (running Ubuntu) and the other is on the DSP (running Qurt RTOS). They use the muorb module to communicate topic data back and forth. The spare i2c on J19 is mapped to the DSP, not the applications processor, so Ubuntu has no access to it. To gain access to it on Ubuntu side with PX4 running would require some new code. This is something that is on our development roadmap but no definitive answer on when we will be able to get to it.

RE: Custom px4-firmware build on StarlingV2
@smilon Yes, in order to build you can follow the README in the voxl-px4 project. The Docker provides the build environment so you need to use it.

RE: QGroundControl Autoconnect when on same network with VOXL SDK
@Sam-Kiley When on public 3G / 4G / 5G networks we use a VPN and assign fixed addresses to each system component with our VPN configuration. You should be able to do a similar thing with your 5G private network. Does your private network have a connection to the Internet or is it self contained? I don't know anything about 5G private networks but I'd be surprised if it didn't have a way to assign the same IP address to a device on the network so that you effectively have a static IP. Earlier versions of the RB5 SDK set the MAV_BROADCAST parameter in PX4 to 1 and PX4 would then use the network broadcast address to send out it's initial messages. Any QGC instance running on the network will receive that broadcast and respond so that you get automatic connection. However, this can be problematic if there are more than one instance of QGC running since you may connect to an instance that you don't want. Also, some wireless networks do not support broadcast.

RE: VOXL2: Adjusting bandwith of video streaming
@Curious By default the voxl-streamer application assumes a wireless link. But you can change the configuration as needed. See https://docs.modalai.com/voxl-streamer/

RE: voxl-streamer client repetitive connect/disconnect
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.

RE: Request for QURT Compatibility for OSD Program
@JP-Drone Looks like there was an issue with the handling of strings in the DSP version of the code. I made an update, can you try it now? http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.14.0-2.0.89-202412270902_arm64.deb

RE: ArduPilot on Voxl2
@TomP The update to support all 8 PWM outputs from the IO board is now in mainline. You can get it in the latest build posted here: https://firmware.ardupilot.org/Copter/latest/QURT/

RE: Request for QURT Compatibility for OSD Program
@JP-Drone Does it work as expected when you try it from the J10 port (/dev/ttyHS0)?

RE: Request for QURT Compatibility for OSD Program
@JP-Drone No, that isn't expected. Can you send the values of all OSD parameters? What type of VTX unit are you connecting to? If you set OSD_STATUS_ROW to -1 do both messages disappear or only one of them? I see it is also showing the VIO status which is controlled by the parameters OSD_VIO_COL and OSD_VIO_ROW.

RE: DSP Uart Application
@scosgrove Unfortunately, there isn't a whole lot of useful documentation about that. You kind of have to look through the Qualcomm source code to get an idea of what it is doing. One idea is to use the Qualcomm
mini-dm
debug tool. It is included with the Hexagon SDK. If you are connected to the USB port (i.e. you can use adb) then you can use mini-dm. This will output more information from the DSP as it is running and you may see some error messages coming out when you are seeing issues with data loss. -
RE: TBS crossfire nano receiver with VOXL 2 USB3.0 / UART Expansion Adapter M0151-1-00 expansion board.
@voxl-phoenix J19 has pins for 2 UARTs. We put GNSS on one and RC on the other. So if you are able to hook up everything correctly, configure the TBS crossfire receiver correctly, and configure PX4 correctly then it should work.

RE: ArduPilot on Voxl2
@Eric-Katzfey I will need to add the support for up to 8 PWM outputs on VOXL 2 IO board. Right now it only supports 4. You should be able to do test flights without the gimbal with 4 PWM outputs.

RE: ArduPilot on Voxl2
@TomP I have updated the documentation at https://docs.modalai.com/voxl-ardupilot/. The VOXL 2 IO board with up to 4 PWM outputs is now supported and has been tested on a quadcopter with 4 PWM ESCs. You should be able to use this for arduplane now. We are putting together our own fixed wing test platform and hope to begin testing soon.

RE: TBS crossfire nano receiver with VOXL 2 USB3.0 / UART Expansion Adapter M0151-1-00 expansion board.
@voxl-phoenix VOXL 2 is really not a great place to start if you are new to drones. And the best way to start with a VOXL 2 is with one of our pre-built drones like the Starling 2 (https://www.modalai.com/products/starling-2), not with a bare board. The standard place to connect RC for PX4 is J19.

RE: TBS crossfire nano receiver with VOXL 2 USB3.0 / UART Expansion Adapter M0151-1-00 expansion board.
@voxl-phoenix What PX4 driver are you intending to use with it? And why don't you want to attach it to the "normal" RC UART on J19?
