Thanks thats just what i need, its for use as a serial link for android rather than bluetooth audio. I also wanted todo something for an iOS device to but apparently apple doesn't support SPP so you need to register as a developer before you can continue, but i guess ill try that at a later date if i need to get my hands on an authentication co-processor.
This is my first bluetooth project it will be interesting, ive found this processor based on your reply
**broken link removed**
thanks again
