@Alex-Kushleyev Thanks. On the both drones, we used them exactly out of the box, no modifications. The issues we experienced before installing the ALFA adapter on the first drone.
For example for the 5/8 message, the model MRB-D0012-4-V4-C28-M36-T8-K2 is using the daughter board with the BOTS chip (I think it's board MDK-M0213-1-00).
Hi Alex,
Thanks - As @Adnaan-Yunus mentioned, we switched over to the ALFA wifi and moved forward with that drone. But, we just received a new drone (model MRB-D0012-4-V4-C28-M36-T8-K2) and are experiencing similar issues. I managed to catch some log messages when the wifi went down. TLDR: it looks like the USB disconnected unexpectedly; the drone was stationary on a table top when this happened.
Some additional context: the only configuration changes we made since unboxing was via voxl-wifi and we altered the RTSP address in voxl-mavcam-manager.conf. QGC was running when the USB disconnected with RTSP video displayed. The drone was not armed.
Here's the configuration (everything looks as we expect).
$ voxl-wifi

On another machine, we can ping and access to the web frontend http://192.168.30.104 looks good.

However, with a few minutes the ping's stopped. I monitored dmesg -w and here's what was output when the wifi went down:

If I now run voxl-wifi and enter the same settings, the wifi will come back online. I was able to reproduce this issue several times.
Hello, I see the CAD/STEP files for the Starling Max v2 here: https://developer.modalai.com/asset/6
Is there a model for v3 (with the elevated GPS mount)?
