How to create Bluetooth PAN?

I’m trying to create a Bluetooth PAN network because of a device that has broken wifi (USB wifi also not possible because there are no drivers for that device).

Seems that OpenWrt is missing the bt-network binary completely, and dbus-send also fails -

root@gateway:~# dbus-send --system --dest=org.bluez /org/bluez/hci0 --type=method_call --print-reply org.bluez.NetworkServer1.Register string:"nap"
Error org.freedesktop.DBus.Error.UnknownMethod: Method "Register" with signature "s" on interface "org.bluez.NetworkServer1" doesn't exist

I’d appreciate any thoughts on how to get this running.
