No GPs lock for vehicle

[Adeeb Abbas]

I can second the same issue. Getting the following for the GPS message check command -

voxl2:~$ px4-listener sensor_gps
never published

Recently received a brand new sentinel drone and wanted to try out indoor flight however QGroundControl prevents arming due to no GPS lock error. Quite similar to what's mentioned by the OP. Hoping to get a response soon. Thanks!

Please let me know if there's anything else you'd need.

@M-al-khatib If you are comfortable editing text files in Linux then you can try the same instructions that I provided him on that thread: https://forum.modalai.com/topic/2317/sentinel-px4-no-gps-lock-and-firmware-problem/21

"I can't find the command 'qshell gps start -d 7 -b 115200' or 'qshell gps start' in the file '/etc/modalai/voxl-px4.config'."

@Eric-Katzfey
I have now arrived at this stage, yet my GPS count remains at zero.

@M-al-khatib
While presently utilizing the exact same parameter, the QGS occasionally presents a GPS error, whereas at other instances, it indicates normal GPS functionality.

@M-al-khatib What drone do you have? A Sentinel? If so, can you please update your software to SDK 1.0.0?

[M. al-khatib]

@Eric-Katzfey
Okay, I'm done, and the drone got GPS this is video link.

However, I mistakenly used the power adapter instead of the battery when I unplugged it to switch to flight on battery mode, so there was no GPS signal.

my sdk now is 1.0.0
and my firmware Version 1.14.0dev
