I'd like to connect Arduino with bluetooth shield to multiple bluetooth devices (TV & baby monitor), plug a corded headset into the contraption, sprinkle LEDs on top, and do the following:
If there is a signal above certain threshold coming from the baby monitor listen to a mix of TV and baby monitor audio with LEDs blinking; otherwise listen only to TV audio.
Thus the questions:
Can bluetooth connect with multiple devices simultaneously?
What do I need to implement that?
