USBC Port as Ethernet interface

tom — Wed, 27 Aug 2025 09:48:04 GMT

@Huynh-Gremsy You cannot connect peripherals to the USBC port in that way, you'll have to use one of our add-on boards that breakout USB ports

Drone Flipped Over When Initial Flying Status

Alex Kushleyev — Fri, 14 Mar 2025 07:48:39 GMT

Hello @selina, Do you have any px4 logs from the original flight(s) which exhibited the flipping behavior? The logs contain the commanded and actual RPM (as well as many other things) and we can check what happened. If you don't have any sensitive information (gps location that you dont want to share, etc), you could upload the log to https://review.px4.io/ and that will give you some information and we will be able to grab that log and further analyze it to parse the custom ESC messages that standard px4 flight review does not support. Alex

Recording tracking camera video compressed and coloured

Alex Kushleyev — Mon, 10 Mar 2025 17:00:59 GMT

@vjuliani , the tracking camera ( i assume ov7251 or AR0144) is monochrome, so you can not make the image colored. You can install the latest version of the voxl-streamer from dev (nightly builds) http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/ and it should allow you to encode h265. Alex

Not connecting to QGC after flashing the Rb5

tahawaru — Thu, 27 Feb 2025 13:55:12 GMT

@tom After flashing, I cannot connect to the QGC. After setting up the IP address, I try to connect via UDP using the IP and port 14550, this is what I get [image: 1740736258690-e032a3a6-32d8-4b3f-9f56-dba442f9aaa4-image.png] drone(connected) is the one not connecting to QGC.

[URGENT] RB5 VOXL2 doesn't recognize replaced hires camera

smilon — Thu, 06 Feb 2025 14:17:42 GMT

@Alex-Kushleyev Dear Alex, It's the M0025-002 high resolution camera. Perhaps the connection sodder was loose and it popped off real easily. In hindsight, perhaps it's not worth anyone's time. If you can provide any repair tricks that'd be neat otherwise I'll probably have to send a new order in. Best, Milton

tom — Tue, 28 Jan 2025 16:04:45 GMT

@Amin-Bassiri You can either fully re-flash the drone or just run voxl-configure-mpa in order to bring the drone back to it's default state based on the SKU

@smilon The parameter EKF2_REQ_SACC sets the maximum allowable speed accuracy. If you increase that value does the warning go away? Can you post a log?

RB5 VOXL support deprecated?

what’s the function of this module?

Eric Katzfey — Tue, 02 Apr 2024 19:33:58 GMT

@Advait-Pandit You can trace the packets used for the QGC connection with tcpdump and compare against what is happening with mavsdk. That should help you to understand what is going wrong.

@Advait-Pandit Please open a new thread for this new topic. Also, you are asking about a PX4 software behavior so it would be good to ask that question on the PX4 forum also.
