As in which device initiates connection (client) and which device responds to a connection request (server). you might want to try and set class of device for ubt0 to "01:01:0c", "01:01:00" or perhaps "01:05:00", make sure that ubt0 is "discoverable" and "connectable" and give it a go. ideally, if you have bluetooth GPS you can get class of device from it and set ubt0 to exactly the same value. you will also need to to provide serial port service on ubt0 (freebsd side). thanks max
