    I'm looking for some low-cost Bluetooth modules for the ability to easily
    add Bluetooth capability to some of my designs. I suppose something under
    $20 would be acceptable. I need the module to be self contained--just
    solder onto the board and communicate to it with a micro. I module that
    manages itself would also be desirable. A SPI or I2C type interface would
    be preferred.

    Does anyone have and leads or sources for something like this? Thanks.

  3. Well, if you can solder BGA.....

    Be aware though that these tranceivers are not complete bluetooth modules
    and certified as end-product. Which means that your design is not FCC
    approved by default. If you use a module from Ezurio (www.ezurio.com, former
    TDK) your product is FCC approved for the BT part because these modules are
    approved as end-product and come with a sticker you stick on the outside of
    your product to comply with the rules.

    I use the Ezurio module, and something else you get with a completely
    pre-approved module is the right to use the Bluetooth symbol. If you do
    your own implementation, and you want to use the Bluetooth symbol,
    you'll need to go through the approvals process (about $10k). If you
    don't need the symbol, then it depends what you need - Gennum
    (http://www.gennum.com/) makes a module as well.

    Cheers
