Rapid beeps using LM-BT-16-4

[RayC]

Hi

when ever I plug a battery into a truck trailer using a bluetooth module I hear rapid beeping coming from the trailer. What situations cause a bluetooth module to beep?

I have searched for Beep, Audio warning, beeping, warning but I cannot find any mention of these words. Maybe it was lost in translation.

The module is bluetooth-connected to an SFR1.
The trailer responds to transmitter commands for lights.

Thanks

Ray

You can ignore this as it seems to be due to servo positions.
