Current status of project:

- BC-127 chip: Great sound, AVRCP commands not working due to the slowness/lockup bug.

- RN-52 chip: Perfect AVRCP implementation with instantaneous command transmission. Iffy/buggy pairing that requires some custom software fiddling in order to make it work reliably. Iffy UART command interface which only accepts commands intermittently. Worst of all: Tons of static and ground loop noise on the line inputs, regardless of which devboard I use or how everything is connected and grounded.

So I've tried two bluetooth chips and run into show-stopper problems with both of them. Anyone know of a third bluetooth A2DP/AVRCP chip I can try? :-)
