How can you transmit audio using a Bluetooth Dongle? Answered
I'm just a beginner with Arduino and what I'm trying to do is take an incoming audio signal and then transmitted through a Bluetooth dongle. I am using a USB Host shield that is connected to a Sennheiser BTD 800 USB Bluetooth Network Card. I've currently just been messing about with this SPP sketch from the USB Host shield library 2.0. What I'm wanting to do is to display the incoming audio signal in the plotter window. Pictures of the sketch are down below. If anyone has any ideas on how to program it to do this, it would be much appreciated.
