16f648 + Bluetooth USB dongle

[MegaADY]

Hello all. I have a quite simple task. I have a data logger with Pic 16f648 and 24lc515. I want to connect a B15 luetooth USB adapter, to download the data stored in 24lc515 on Nokia 6600. The nokia part is quite easy for me, as I have the required Symbian knowledges to build the mobile application. I never worked with USB on a pic. ... and I am quite in a hurry.... I don't have enough time to experiment. Does anyone has some related sources ? How can I connect BT adapter to pic ? Do I have to use HW USART ? Thank you

Rather than trying to interface a usb dongle to your project it may be easier to use a dedicated bluetooth chip as these will give you serial data and do the majority of the hard work.
I don't have any code but here is a datasheet for such a chip.

You basically need the chip an antenna (they make surface mount versions) and the rest seems straight forward.

Look around page 24 for interfacing info. I came across a Toshiba chip which only had 8pins which is a bit more managable but I couldn't find an english datasheet.

If you are in a real hurry you can buy rs232 BT dongles
