Hello,
I connected the active buzzer according to the instructions to the AUX OUT port in Orange Cube+. I set in Mission Planner servo12_function (AUX OUT 4) to 138 (Alarm). The buzzer works, it makes clear informative sounds, but immediately after connecting the power to the drone, the buzzer makes a very loud and annoying sound for about 6 seconds.
What do you think, is it a matter of some parameter that has been set wrong, or the buzzer itself?
I attach a video:
