Is it possible for a device to have multiple services with the same UUID? If not, is that a reasonable thing to key it off? I noticed the list of services in dbus-api.txt, but it currently seems somewhat smaller than the number of available profiles. > One of the bigger goals is a working SDP cache for these kind of task > and the knowledge when to refresh the SDP records for a specific > service.

Is there a practical way of knowing when the device has rebooted? If not, is it possible to simply check the channel on every connection attempt? I'm keen on working on this stuff, but my experience of bluetooth is mostly at the ui level rather than the protocol level. From my point of view, I just want a good way of providing "Get an RFCOMM connection to this device" to user applications :) Thanks, -- Matthew Garrett | mjg59@srcf.ucam.org ------------------------------------------------------------------------- Using Tomcat but need to do more?
