Hi Marcel, Could you please provide me answer of below query. When BT 6Lowpan interface is UP after BLE & IPSP L2CAP connection (Say for example "bt0"). I don't find interface is configured with inet6/IPv6 address which should be configured during device initialization. The snapshot is here: sh-4.1# ifconfig bt0: flags=4177<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280 unspec 00-02-FA-FF-FE-72-2D-17-00-00-00-00-00-00-00-00 txqueuelen 0 (UNSPEC) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 My query is how IPv6 address is configured or generated for BT interface? Or the process which should be followed to get IPv6 address configured ? Please give me some pointer in kernel code also, where to check?
