I can confirm his bug for 12.04 with NetworkManager 0.9.4 - the logs look similar to Martin's.
[Tried to establish a connection by this way because the internal UMTS card of the Samsung NC10 netbook is handled buggy by NM... so I ran from on problem into another. Frustrating :-/. pon/poff in combination with rfcomm is working.] Is there a way I can help as an ordinary user? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/583728 Title: rfcomm device gets ignored my network manager 0.8.0 Status in “network-manager” package in Ubuntu: Incomplete Bug description: Binary package hint: network-manager When the rfcomm port get registered in blueman, network manager ignores the rfcomm port, because it thinks, that no bluetooth device is connected to it.

It used to in older versions of nm (pre 0.7.0, I think) Establishing the connection using pon/poff is working perfectly over the rfcomm device.
