Yeah, software serial works real good and I didn't need to buy another Arduino, the one I had lying around is doing well. I even tried two different Software Serial libraries, the default one and the AltSoftSerial one.
I have a pretty good working program which will theoretically translate the AVRCP commands from the bluetooth into play/pause/next/previous on the Empeg serial port. But I only have it runnig in debug mode tethered to my computer right now: I'm awaiting an RS-232 shield for the Arduino to come in the mail to make its true functionality a reality.
My only issue with the BC127 purpletooth jamboree board is that when I send an AVRCP command from my stereo (for instance "next track" on the car stereo touchscreen or the steering wheel control), then there is sometimes a significant timing delay before the module receives it and notifies me on its serial port that it has received the command. Not sure how to fix this.
Did anyone ever get a thing working on the empeg itself which would display MP3 track titles and artists on the serial port output? I don't recall if that ever happened. The reason I ask is that I now also know the commands and protocols to tell the purpletooth board to send that stuff up to the car stereo to display on its LCD screen. I could scrape that stuff with the Arduino and send it up.
