Hello All,
We are looking for a bluetooth module for short range connectivity to Pocket PCs. I thought about USB and RF but USB needs wires and RF (Nordic etc) is propriatary and would need something on the IPaq end.
So we thought about using Bluetooth.
I did a quick google search and there seems to be quite a number of 'Bluetooth to Serial Port' type of modules that look suitable (ie. all I want is a serial port connection from the AVR to the module and the module does all the Bluetooth magic.

My question is (finally ;-)) has anypone played with any of these modules and would care to share their experiences.
Availability in Australia would also be an advanatage.

Thanks In Advance

There is a "Wireless USB" promoted by Cypress and others. But, I have doubts about its availability and applicability in this sort of application.

This is the very same thing I've been trying to do. Alloy Computer products have a BT RS232-RS232 product that they say will talk to Ipaqs and the like but the price for two of them is AUD$230 abouts. I purchased a dongle to convert a GPS receiver to BT for AUD$100 that has a taiwan manufactured BT module in it which is also sold by Benelec (in your part of the world). Whilst my PC and Ipaq see it as a serial device - I have had no luck in getting real communications happening. I've tried getting info from Benelec - but all they seem to tell me is that the baud rate is fixed at 115200baud. These modules use the Cambridge Silicon Radio chips of which you can download the datasheet (www.csr.com) but it seems you need to run a program to set various mode and baud rate info - this program comes with their (expensive) development kit.

So if you find a solution please email me on russbul@internode.on.net!

Maybe Multi-Tech (www.multitech.com) Part #: MTS2BTSMI . I think you can get it for US $62. Have not used it yet but should do what you want.
