    Hi...I need help to make system with wireless connection. There are
    devices that send input to uC (8052) on wire less connection, and then
    the uC connect to PC. One alternative that I can use is blue tooth, but
    I don't know what to do with that...any body can help me...I have
    search in google about tutorial, but I don't find one that easy to
    understand....or any other suggestion about wireless connection....?
    Thanx b4
     
  2. Serach for Nluetooth Modules with builtin antennas and serial output. You
    must program those modues to have an ID and password, but then you simply
    connect them to your microcontroller and they appear (mostly) like a simple
    serial cable between your PC and uC. This is especially great if you host
    computer has builtin BT (Many PCs, Laptops, but also phones and handhelds).
    Don't forget the built-in antenna, or you are up for a lot of trouble.

    There are a lot of HF tranceivers out there, to that have a serial port.
    However, you need two, and they do not have a protocol. You'd have to take
    care of checksums, bad connections etc. yourself. BT on the other hand is an
    all-or-nothing connection. Your bytes will either be there or not, but you
    will never get faulty bytes.
