    I use the module below.
    As soon as the device is connected, I want to detect this and trigger a different circuit.
    I'm looking for a signal that I can get on the chip

    Thank you in advance to those who helped.

    Connected how?
    - Bluetooth connection established?
    - USB plug inserted?
    - Headphone jack inserted?
    A signal from the chip on the module you can tap into or what?

    Please be a tad more specific.
