Microcontroller in Bluetooth modules

    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.

  3. 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?
  4. 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. 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
