This isn't the TomTom Remote anymore, but a Sony Ericsson phone. I'm pretty certain that I'd be able to reproduce the problem with another adapter. <snip> > Yep.

It seems to me that the loss is only temporary, and part of the pairing process. Is it the reverse SDP finishing?

Could you walk me through the pairing process, remote initiated, for a pre-2.1 device? I don't understand why I'm seeing a complete disconnection from the remote device.
