I'm currently writing an API for Visual Basic to provide a range of Bluetooth services to applications. These will communicate with the large number of bluetooth devices (PC) which use virtual comm ports to provide access.

Everything is going ok except I have a question about ServiceSearchRequests. You need to send a UUID for the service you're searching for - but is there a list of currently used ones? I.e. If I want to search and see if a device (e.g. my Nokia 7650) supports OBEX File Transfer then where can I find the UUID for this?

Many thanks,
