Here is what we’re thinking of ordering: http://www.blueradios.com/BR-SC40A.pdf
But we’re still unsure about how to implement the audio PCM channel…. Trying to gather as much information as possible before we start hacking this chip.

During the past week we’ve been working hard on getting the two to talk in a stable manner. There were many hurdles along the way, but we’ve managed to get a very stable connection between our processing app (running on a PC) and the BlueSMIRF chip from sparkfun, which we connected to a microchip PIC [...]
