@tom thanks! It works. I had used the same solution but a wrong partition number was the culprit.

@mbahrami You can try that same solution, just substitute "wlan0" instead of "eth0"

Where can I find TELEM 1 port in RB5 drone?

Thank you both @Chad-Sweet and @tom for being super responsive on this technical forum.

@Chad-Sweet

Thanks, @modaltb! yes, that seems to be the cause; we received two sentinel drones yesterday and for the same reason they have not had GPS signal available either. But that's ok, we don't need GPS for indoor flight tests.

could you please comment on the odometery problem which I mentioned in the first post? I have two odemetry components with id=1 and id=197 in MAVLink Inspector in QGC. The odometry component with id=1 works fine and voxl-inpsect-imu outputs correct values in the VIO-enabled, GPS-disabled setting. But I get invalid local position for ekf2 status in MAVlink console and "reject position mode" message when try to fly the drone with RC in position mode.

do I need to reset the PX4 firmware?

thanks

No flow control.... really just need GND, Rx, Tx

Modal AI ESC&2203.5 -- I don't see any reason why this wouldn't work.

Battery voltage selection depends on how fast you need to spin the given prop of choice to generate sufficient lift/performance you need in your platform. If you spin the motor at one speed with 3S and that generates the performance you need then go with that. If you move to 4S and in doing so get the performance you want in terms of speed, endurance etc then go with 4S. Really depends on what your goals are. You can pick up a variety of battery pack configurations from any drone/FPV store and try those out -- just make sure you match your connector or get an adapter.

Here are some posts on USB Cameras. I have tried this with some -- it works. https://docs.modalai.com/uvc-streaming/

For something like the Zed2 you probably need some custom drivers on the VOXL to work properly.

Re: other color cameras -- defer to the ModalAI team on those.

Hope this helps,
