Thank you for answer.
I try to execute /bluez/test/test_network.
It also caused same problem.
The problem is that device is immediately "org.bluez.Device1 disconnect" after returning interface (bnep0) and signal ("org.bluez.network1 -> connected true").
<------------------------------ bluetooth daemon log -------------------------------->
bluetoothd[5041]: profiles/network/connection.c:connection_connect() id 4374
bluetoothd[5041]: src/adapter.c:connected_callback() hci0 device 12:23:34:45:4C:AB connected eir_len 7

bluetoothd[5041]: bnep0 connected
Connected to 12:23:34:45:4C:AB service nap, interface bnep0
Press CTRL-C to disconnect

<------------------------------------------------------------------------------------------------------>
So, I try to execute /bluez/tools/bneptest.
( ./bneptest -b bnep0 -n hci0 -c 12:23:34:45:4C:AB )
Then, I will command "dhclient bnep0". I can check the ping test well.
Why device is disconnected..?
Thank you:)

Next time use a pastebin like service or an attachment for HCI trace.

It is actually quite simple, dbus-send disconnects from D-Bus once it
exit which will make bluetoothd to release the connection, if you want
the network to stay up you can use the following:
