NAP/GN with bluez-4

["y.dmitry@gmail.com" <y.dmitry@gmail.com>]

Hi!

Can't setup NAP-server with bluez-4 (versions 4.39, 4.47). Remote device
can't discover any services. But when i trying to run  'simple-service'
script from sources, i can see a "Serial Port" service on remote device.
Service disappears when script canceled. As I understand at this point,
all ok with connectivity and access rights.

I mean linux box must became an Access Point for phone, netbook, etc.

# ifconfig -a|grep 'pan|bnep'
pan0      Link encap:Ethernet  HWaddr 3a:cb:41:e4:19:97

(pan0 iface not disappears when bluetoothd stops. But it's ok when i set
pan1 in config)


I can see both NAP/GN records with 'sdptool browse local'. After
'simple-service' script new record appears.
I dumped some bt traffic with 'hcidump' and saw a "serial port" record
transmission. It seems, that somewhy bluez completely ignores any
builtin records about network services.

I tried several userland tools (blueman, bluez-gnome) with no success.
bluez-gnome has no support for local services. blueman has such broken
support.

I tried to play a little with python and dbus (few 'simple-service'
script modifications). No success here too.

Am I missed something?
