I'd like to build an Arduino device to stream audio via bluetooth.
I already have this https://www.sparkfun.com/products/11125 (https://www.sparkfun.com/products/11125) and it works fine with my wired headsets.
How can I insert a bluetooth module (like this ? https://www.sparkfun.com/products/11678 (https://www.sparkfun.com/products/11678)) to send audio from my Arduino + WTV020SD to any commercial bluetooth headsets.
I was thinking you could get the usb host shield and add a bluetooth usb module to it, but the tones would probably be slower to get to the speakers. But I have very little experience with audio, so I am not 100% sure I am correct.
