Hi Joe,

We have been developing a product for this since January.

There are a lot of challenges because the Pocket PC will typically be using
the Widcomm stack, while your Smartphone is using the MS Bluetooth stack. We
have come across all sorts of issues including the maximum number of bytes
that can reliably be sent in each frame.

We have the components you are looking for (C code at the driver level,
wrapped with .NET CF for you to write your apps with). These are in final
testing now. If you would be interested in trying these out, I can have a
beta to you by Monday. Will run the latest version past another client first
today.

In our particular case, we have a headless CE device (Bluetooth, GPRS, GPS)
that is running the MS Bluetooth stack and a Pocket PC that is running the
Widcomm stack.

You Smartphone will have the MS Bluetooth stack so it will be essentially
the same as our configuration.

Our software includes all sorts of functionality such as:
-automatic connection as the device comes into range
-limiting pairing to specific devices
-retransmits if incorrect data received
-retransmits if the devices go out of range
-sending named files
-buffering of data at each end in files
-sending data without buffering for speed

We hope to publish the API on our website soon, maybe over the weekend.

Please send me an email offline to discuss further.

Regards
