Microcontroller in Bluetooth modules

Hello!

I have a very general question about Bluetooth modules:
Most of the modules have an implemented microcontroller and
programmable I/O-ports. Does this mean that I can write a C-program
for this controller and so implementing my application? Or do I have
to buy a seperate microcontroller and connect it by UART or SPI to the
Bluetooth module?

What I need is a Bluetooth based communication which enables me to
control a mobile system. Therefore I need to write some upper layer
application which makes it possible to control another microcontroller
via RS232 and also use some I/O-ports.

Thank you in advance for your answers,
Susanne Fischer

Yes. :)

Zeevo Serial and similar products are well suited to talk to serial ports
directly, and of course you can embed another micro there to do any
setup/teardown and protocol translation.

If you're lucky, you might find one with a processor inside that you can get
cheap dev tools for, but don't count on it.

Does this mean, that I can write software for the microcontroller
inside the BT module only if I have the corresponding development kit?
Isn't anything like that included when I buy such a module?
Where can I get information on where to get dev tools for which BT
module and how much could such a software cost?

well, the CSR chips have an embedded uC on which you can run a small (!)
application. So the answer to this question is yes.

You need the dedicated software development kit and it's usually a great help to
have the hardware development kit for debugging purposes.

www.csrsupport.com for more answers (sorry, I don't work with s/w development,
so I do't know the specifics of what is needed or costs).

Best Regards
