I had Bluetooth tethering working well from Android (Nexus 7, and I'm sure GTab 10.1) using BluetoothDUN on N900 and BlueVPN on Android, but it no longer seems to work. I use it sporadically, so I'm not sure what updates have been applied on either side, unfortunately, and thus which side has broken the connection but about a month or two ago it was working ok.

I tried it on both my devices, before and after the latest BlueVPN update and it failed (but there could have been a previous one) so it does somewhat point to the N900. When I try to connect it seems to negotiate the Bluetooth connection ok, but then sits there on "modem negotiating", turning on logging on BlueVPN I get the following:-

So it seems like it's not getting an IP address back. I can't find any logs on the N900 for BluetoothDUN.
Any ideas where the issue might lie, or where I can check on the phone for logs?
Thx, MH
