How to raise PAN Bluetooth on OpenWrt?

Question

Bluetooth

We have: Openwrt 15.x, household router with usb, some kind of usb dongle. The iron is working, it scans, it sees devices nearby, it pairs normally. The service added (spdtool add NAP) to the list, Windows sees the device, steams and in the context menu offers "Connect via -> Access point", but does not want to connect (which is logical, because it is not configured). How to raise bnep0 (there is no such interface), how to bridge grids? It seems that this is done by python scripts from the bluez-examples package, but a) the scripts do not work, they say "an error in import dbus, there is no such module", b) it doesn't matter , because. bluez does not expose its interfaces to dbus:

# dbus-send --system --type=method_call --print-reply --dest=org.freedesktop.DBus /org/freedesktop/DBus org.freedesktop.DBus.ListNames
method return time=1453795633.305923 sender=org.freedesktop.DBus -> destination=:1.7 serial=3 reply_serial=2
   array [
      string "org.freedesktop.DBus"
      string ":1.7"
      string ":1.4"
      string "org.bluez"
   ]

#dbus-send --system --type=method_call --print-reply --dest=org.bluez / org.freedesktop.DBus.Introspectable.Introspect
method return time=1453795640.171153 sender=:1.4 -> destination=:1.8 serial=32 reply_serial=2
   string "<!DOCTYPE node PUBLIC "-//freedesktop//DTD D-BUS Object Introspection 1.0//EN"
"http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd">
<node><interface name="org.freedesktop.DBus.Introspectable"><method name="Introspect"><arg name="xml" type="s" direction="out"/>
</method></interface><interface name="org.freedesktop.DBus.ObjectManager"><method name="GetManagedObjects"><arg name="objects" type="a{oa{sa{sv}}}" direction="out"/>
</method><signal name="InterfacesAdded"><arg name="object" type="o"/>
<arg name="interfaces" type="a{sa{sv}}"/>
</signal>
<signal name="InterfacesRemoved"><arg name="object" type="o"/>
<arg name="interfaces" type="as"/>
</signal>
</interface><node name="org"/></node>"

(It didn't tell me anything even with Google, but suddenly someone Copenhagen)
So,
1. Are there ways to raise the PAN without accessing dbus? (I don't have pand and it's like deprecate-zeros 5 years ago)
3. If not, how to fix bluez and raise PAN via dbus?
