I ordered the RN-52 BT module from Amazon and it arrived yesterday. As soon as I get a day off work, I'll be working out the specifics on how I am going to connect to and control it. I plan on using the I2S output of the module but I don't yet have the Wolfson Audio module that will accept the I2S signals. As a result, I going to connect my Saleae Logic to the BT module and check the I2S output against what the Wolfson chip expects (as per the WM88024 datasheet). This whole project hinges on being able to get the audio to work as I want it to, and so this is a pretty big step. I also need to work out how to use both the streaming audio profile and hands-free profile on the module, along with how to switch between them. I may even go as far as trying to measure audio degradation over the BT link. My next update will detail my findings.

On a related note, I'll be ordering the Wolfson Audio S/PDIF module within a week or so. Here's the link to it: Twisted Pear Audio S/PDIF Transceiver. This module will be connected to an optical output board that I plan on custom building. It will have at least two outputs (identical data on both/all) to feed the DAC's/amplifiers.
