Generally, an RFCOMM error means just what you might think. The Bluetooth radio frequency is discovering another device, attempting to connect, but then fails. In your case, I'm pretty sure it's because the DC600 doesn't communicate with the V262. I checked at least 10 sites that sell the DC600 and not one listed V262 as being compatible. Generally, if something's not listed as being compatible, it isn't, especially with something as esoteric as a bluetooth adapter. It's always a good idea to do you own research before making a purchase, especially if you have someone telling you there's "no reason it shouldn't work". That should send up an immediate red flag that that person also doesn't know if it will work.
