Another snag... Seems like the voxl-vision-px4 is spotty at starting. I am trying to fly again and no luck. I ran the status command and the same failure as before.

I just did another test randomly while eating my lunch and it worked as expected. So I did a maiden and checked stabilize, althold, and position mode and all modes flew well. We have lots of snow here so cant test too much more outdoors.

I've been testing on a Macbook Pro. I can get QGC via the USB port, just not via Wifi. And the motors dont spin above minimum armed PWM.

No luck on different computer. I just tried the ESC cal as well and no luck.

Looks like that worked.

I edited the QGC IP to my laptop's IP and QGC still doesnt see it. I will try from a different computer.

I run into the same issue when I check the voxl vision status. Active: Failed. There is nothing on the voxl-vision-px4.conf file. It's not properly configuring that file.

@modaltb I may have modified it, not even sure. I'm still learning the hardcore software side of this. I'm a hardware guy.

Now it says only "error parsing config file before: ?
Segmentation fault"

This is what I typed and what I get.

~ # systemctl stop voxl-vision-px4
~ # voxl-vision-px4 -d

This is what I see. I also cannot get to QGC through VOXL.

@modaltb No magnetometer. I installed the No mag params file, as well as a few others, but I'd like to get your instructions. Mavlink inspector shows it not going above 1075.

In the end goal, When I arm the copter, the motors stay at the ESC armed throttle level, despite seeing throttle input from the RC. Once I get this resolved, should it work, or are they unrelated?

I just reverted back to the ModalAI version of V1.10 and still having the same issues. It must be somehow related to my system.

@modaltb I have V1.11.3 loaded onto the Flight deck board.

I just had a BEC failure, so I cant access the FC,. Will swap and let you know. I believe I updated to 1.11 via QGC.

After following the wiki for ESC calibration, once I type Y for all of the prompts and it should run, I get an immediate error. I'm able to connect via QGC. QGC is closed out and it is able to access the port. Errors are
line 269 in <module>
mavcall()
line 246 in mavcal
if not mavshell.connect()
line 74, in connect
ret = selv.mav.wait_heartbeat(blocking=true, timeout=10)
TypeError: wait_heartbeat() got an unexpected keyword argument 'timeout'

Any ideas? From what I think I'm seeing is that there was a timeout in the connection maybe?
