I have a Samsung HM1300 headset and want to emulate the call button signal via a microcontroller.
Here is a pic of the inside of the headset:
The gold button is the call button. I see the solder points (the 4 points around the button). Do you think it's plausible to solder other wires to those points? I would like to simulate a button press via an Arduino to the Bluetooth headset by soldering wires to the current button circuitry.
What do you think? If I am not clear on the question, please let me know.
