    Bluetooth, microcontroller, PC Meltdown!

    Hello!
    I am yet to start my final year project. The first stage involves transmission of data from a Microcontroller to my desktop PC. I have decided to use bluetooth modules/dongles at each end to do the same. Trouble is, I don't know where to start. I don't know what kind of modules I can use, how I can interface the dongle/module to the microcontroller,yada yada. I am looking for a range of 10-20 mts. Any inputs and suggestions would be most welcome.
    Thanks.

    You can use this thread as reference.

    Also, you will need to buy a Bluetooth module that has UART or SPI interface such as these two:

    Re: Bluetooth, microcontroller, PC Meltdown!

    I have been using Bluegiga wt11 (need RTS signal!!!) for mcu side and USB Mini-Bluetooth GEMBIRD on PC side. This is the easiest and safe way to wireless communication I know.

    Simple and practically used by me many times.

    If you know wired rs232 communication, you won.
    Distance about 60m I can confirm.

    On PC side sometimes you can face some troubles when you have installed a communication programs for cell phone or camera,...

    good luck8)

    Re: Bluetooth, microcontroller, PC Meltdown!

    Thanks a bunch for all your help. I think I know now how I can go about it.
    Also, could any of you confirm if this module could be used at the microcontroller end. I don't want to use a dongle here as it would become tedious to have to interface it.
    Thanks.

    Re: Bluetooth, microcontroller, PC Meltdown!

    I have used a Bluegiga WT12 connected via the serial interface to a UART on a PIC24FJ256GB106. Very easy to use and control.
    It also has USB and SPI interfaces so you have a choice.
