Have a look at Nordic Semiconductor chips, in particular the NRF51822
device. There are various development boards available. The hardware
can be use for Bluetooth and ANT protocols and the protocol stack for
both is available. So far I am very impressed - it makes implementing a
Bluetooth product very simple.

Hi Mike - I used successfully BlueRadios BR-LE4.
Stay away from Amp'd Up BT43 and cousins (buggy).
Presumably you're expecting to use SPP (serial profile).
Don't know what you mean by "SDK" ?
Beware these things comingle status and control
on the single serial connection, including exciting stuff
like sending you status messages in the middle of data,
and without unique prefixes or escape sequences for such
stuff. Nonetheless, workable (if rather annoying).
Hope that helps!
Best Regards, Dave

A friend of mine uses some for an ECU, the hardware one the different modules
are pretty much all identical based on a CSR chipset with varying quality of the software, probably all based on some CSR app-note.
I think he eventually ended with some from a small English company that I can't remember the name of. I don't know if they made the modules or just the software

I haven't looked really as I have not needed one professionally. Try
checking with the distis, Avnet, Arrow, Digikey, Mouser.... Anything
they offer will have documentation.
But with the modules sold on eBay, etc, they are just a chip on a board.
Look up the data sheet for the chip and you have the docs for the
board. You can always buy one and look at it to see how they are
connecting it and what they use for PSU, etc.

Hi Rick,
Yes, I am looking for a serially connected BT module. I know there are many around but I am looking for one where the complete documentation is readily available without having to sweet talk a disty or mfr and which is readily available in small quantities.
Any ideas ?
Thanks,
Mike

Maybe I'm not understanding. How do you expect the BT module to connect
to your system? I am thinking it would be through a serial port? If
so, how much info do you need? These things are a dime a dozen... well,
$6 anyway. What am I not getting?

Hi,
I'm looking for a Bluetooth module for a low-volume product which needs basically a replacement for a serial protocol and for which the complete docs are readily available and which has enough of an sdk (again readily available) to get started in a bare metal system.
My last experience of BT was that suppliers keep their cards very close to their chests as far as docs etc are concerned, anyone know of any exceptionsd to this rule ?
Thanks,
Mike
