Microcontroller in Bluetooth modules

[Susanne]

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).
