we managed to get low resolution streaming from camera 3 (Front Hi-res).

1. Is it possible to get higher resolution camera stream (for example FullHD)?

2. How to get stream from other cameras, for example camera 2 (Front Tracking)?

sh-4.4# rb5-camera-server-configure 

Would you like to enable the camera service?
This will start all cameras in a background process
Selecting yes will start the service, no will disable the service

1) yes
2) no
#? 1

Could you advise how to get stream from cam2? Thanks!

@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.

@RichieRich
Are there any updates or suggestions regarding above mentioned issues? Thanks!

When EFK2_AID_MASK is set to 1, following errors occur:

I emphasize that drone is under clear and sunny sky

Also when I go to QGC - Vehicle setup - Safety, I get this error

@RichieRich

I have made following changes (WO_GPS to 1 and EFK2_AID_MASK to 1 and to 0)

but now I receive following error:

The main GPS LED (blue) slowly blinks, but only in blue color.
The FIX LED has short blinks in blue color.

Could you please advise what to do?

Re-flash solved all the previous issues.

But still I'm unable to arm the unit.

Following instruction provided here
https://docs.modalai.com/Qualcomm-Flight-RB5-user-guide-first-flight/
doesn't help as I receive GPS and AHRS errors (while the unit is placed under open and clear sky).

Regarding the GPS, I receive the "GPS accuracy too low" (while receiving 10-12 satellites).

What could be the cause of these errors?
Also is the GPS necessary to at least test the motors?
Is it possible to fly without the GPS?

@Eric-Katzfey
Will try to re-flash within a day or two, so I'll get back to you with the updates.
