Hi,

i have a Pixhawk who looses all sattelites when i connect the battery.
i suspect the storm32 gimball is the bad guy.

Settings for the Storm32:
Baud: 115
Mav1

Bump. anyone have any idea why the gps signals are fading when powering ut the gimball?

Could you have connected them to the same serial port for that they are interfering with each other?
