Hi all, my groupmates and I are currently working on a senior design project and I’ve run into a bit of a snag that I hope you can help me with.
The parts causing me trouble are the Somo 14-D audio sound module (http://www.sparkfun.com/commerce/produc … ts_id=9534) and the Bluegiga WT-32 bluetooth module (http://www.sparkfun.com/commerce/produc … ts_id=8952). As far as we know the wiring is all correct (though we can’t rule out our own incompetence :P).
Here’s the deal: When hooking a speaker directly to the output of the Somo 14-D, we get sound and its fine. When we hook up the bluetooth source module to a standard headphone jack (coming from an iPhone) and the sink to the speaker, we get audio fine. When we combine the two (source connected to output of Somo 14-D and sink connected to the speaker) we start to experience some issues. Namely, the sound is essentially static with a beat (you can tell its the song, because of the pattern of the static). We’ve tried all sorts of different encoding for the files on the Somo to no avail. We have no clue what to change. Our thought is its a setting on the WT32, but we don’t know what to change (or how much to change it).
Any help would be much appreciated and the sooner the help arrives, the better (as we’re coming close to our deadline).
Thanks in advance Sparkfun-ers!
