  You can just use a USB to Ethernet dongle. Our Doodle Labs integration guide is here https://docs.modalai.com/doodle-labs-user-guide/

  @joshuagaus Even with our new upcoming module we will not support PPM. It looks like there may be some other communication options on that receiver so you may want to review all the possibilities.

  Reading your post again . . . It looks like you'll have to QGCs running, but using the same router. In the response above, I assumed a single GCS. On each drone, go to /etc/modalai. There should be a file qgc-ip.conf or something similar. You can set the IP of the target laptop, so the MAVLink gets routed properly. Let me know if that works.

  @MaxG we are currently low on stock of the replacement parts, but they can be found here on our web store. Please check back in the next week or two and those will be in stock. Replacement landing skids can be special ordered. Do you need the entire skid assembly or just the landing skid itself (black part)? Please send a picture to contact@modalai.com and we can get you the parts that you need!

  Hi Akash, we do not expect much of the Qualcomm Flight RB5 SDK to work on the RB5 dev kit without a significant amount of work.

  RB5 drone streaming from different cameras

  @MJ said in RB5 drone streaming from different cameras: Tracking Hello, At the moment the rb5-streamer only streams video at 640x480 at 30fps. In order to achieve a different resolution, a custom gstreamer implementation will have to be used. The rb5-streamer is based off of the code found here. In order to get streams from other cameras, through rb5-streamer, begin by disabling the camera server for the corresponding camera you'd like to use, and start a new rb5-streamer instance using the -c flag to select the camera index. So for the tracking camera: systemctl stop rb5-camera-server@2 systemctl disable rb5-camera-server@2 rb5-streamer -c 2 A reboot may be required after stopping and disabling the service you'll then be able to access the stream at rtsp://VEHICLES_IP:8554/camera2 Regarding the weird systemctl status rb5-camera-server@2 warning messages, I don't believe I've seen those warning messages show up before. Were the After and Requires fields modified in the service file? These are the appropriate values in case it was modified: After=qmmf-server.service Requires=qmmf-server.service

  @RichieRich GPS unit is mounted by default (as it comes with RB5 5G drone), mast is locked in vertical postion. Turning EKF2_REQ_SACC to 0,75 provided no errors from GPS. Obstacle avoidance was also disabled, so we managed to fly. But I'm still a bit confused why the obstacle avoidance gives error, since the drone was placed on the ground (concrete pavement), no obstacles within few meters, while the minimum distance was set to only 1 m. But this is current setup that works: Many thanks for your help. We'll try to figure this out and provide info in a few days.

  How to set up a static IP in RB5

  If anyone else is interested - I found a way to enable static ip's for ethernet and wlan interfaces. You'll need to install a file like below under /etc/systemd/systetem/ and run the following commands: systemctl enable ipconfig.service systemctl disable dhcpcd.service [Unit] Description=A description for your custom service goes here Requires=systemd-networkd.service After=systemd-networkd-wait-online.service [Service] Type=simple ExecStartPre=/bin/sleep 10 ExecStart=/bin/systemctl restart systemd-networkd.service [Install] WantedBy=multi-user.target You'll also need to add this file under /etc/systemd/network/wlan0.network [Match] Name=wlan0 [Network] Address=192.168.0.169/24 #DHCP=yes Simply installing this service will allow most routers to keep the rb5 address the same when assigning IPs for a lease. Just comment #Address and uncomment DHCP to use dhcp. You will also need to make sure to add the gatway to the routing table: route add default gw $router_IP $network_interface this is best to be configured as a oneshot service where the service has the field Requires=ipconfig.service

  @mrawding yes, we have a fix that will be in the next SDK download, but I'll send an email to the one on this account now and share a link. The issue was tricky to figure out, but when PX4 is not running on the DSP, sensor power rails were being disabled that powered off the UARTs!

  For softap, there are references here on how to enable At some point more flexibility will be added for camera configurations. Right now the shipping configuration is all that is supported. There is already a tracking camera at 45°. You should be able to create a mount to point that straight down if you prefer. Only one active gstreamer instance for each camera can be running. The camera servers use gstreamer to get the camera data and publish that to a named pipe. So if an instance of a camera server is running, then a new gstreamer instance for that same camera can't be started. MAVROS is not pre-installed. That is planned in a future version of the SDK, likely one or two months away. We do have customers using it today though. Note in offboard mode the default behavior is a figure-8. See post here for the fix

  ModalAI is the only manufacturer of Qualcomm Flight RB5 boards We will release more pricing information soon. The VOA functionality creates the depth map and obstacle map on the CPU and passes that information to PX4 running on the DSP. Yes, there is USB expansion, datasheet has all of the details here The USB expansion through the modem carrier board uses JST-style connectors which are more vibration tolerant. The end UAV manufacturer can equip with a fan. HDMI input is not supported at this point

  @Djalma-Ribeiro Awesome thank you, just wanted to make sure your RB5 had the SDK loaded properly, which it does. It's not absolutely necessary to upgrade the SDK, if you do want to you can follow the steps here: https://docs.modalai.com/Qualcomm-Flight-RB5-sdk-installation/#how-to-upgrade One note, if you try to upgrade the SDK while PX4 is running it will fail. So in order to upgrade the SDK you would have to disable PX4 from starting systemctl disable rb5-px4-start and then reboot your drone before upgrading your SDK.

  Hello, In our current release, the rb5 will do a figure 8 when in offboard mode by default. Currently there is no way to disable this. We do however have an updated version of rb5-qvio-server (0.0.7) that'll have figure 8 mode disabled by default. To enable figure 8 mode in this release, you'd use the -f flag to do so. This updated version can be downloaded here. This version of rb5-qvio-server will be included in the next sdk release, but for now it should help you disable figure 8 mode.

  @Hector-Nevarez Thanks for the quick reply. If the camera server are disabled I guess VIO can not work?
