Description Ben 2014-11-14 22:16:29 UTC
It looks like bluetooth PAN does work under Networkmanager.  This is a bit confusing as in the past, the DUN profile was used by Networkmanager to initiate a network connection through the phone.  My proposed fix is to make a USE flag to enable or disable this functionality - I would like at some point to also allow DUN profiles if NM will eventually reintegrate it, but for now, PAN works.

My test build I added a "bluez4" IUSE in my test ebuild, and used a $(use_enable bluez4) instead of hardcoding --enable-bluez4 - which is kind of weird why it should be hardcoded with --enable-bluez4 as bluez5 tends to be installed for other reasons.

Perhaps the better solution is to detect whether bluez4 or bluez5 is installed and use whichever bluez is available; this would be a bit more involved unfortunately and may be easier just to put the bluez4 USE flag in.

Reproducible: Always

Steps to Reproduce:
1. Enable bnep bluetooth network in kernel.
2. Run Networkmanager/nm-tool in Gnome with a paired, PAN enabled cellular phone nearby
Actual Results:  
No PAN available.

Expected Results:  
Should be able to detect PAN and offer networking through PAN

> enables DUN with the bluetooth USE flag

Does this mean that PAN requires the bluetooth use flag to be unset? (I can't get a PAN device to show up; I have bluetooth as a global use flag.)
Comment 3 Ben 2015-09-09 22:45:51 UTC
I should have marked this as verified/fixed as recent versions of NM have PAN enabled as expected.  I just recently looked at the ebuild and it still looks a little wonky to me but does its job (forcing people to use bluez5, but that's ok I suppose, then again not sure if the NM devs are enforcing that anyway).

You do need USE=bluetooth to enable PAN. 

I don't know about the status of bluetooth-DUN however; I haven't been able to use it since bluez4.
