no ping between nrf52 coap server and PC

[nav87]

Hello, I have followed the instructions for openwrt on rpi2 devzone.nordicsemi.com/.../ and was able to establish connection Bluetooth 6lowpan connection between Rpi and nrf52 running coap server. I set up the global prefix and everything, i see that my PC got the ipv6 address with the same global prefix as well. But i am unable to ping between my PC and Rpi or coap server on nrf52. I also made sure set ipv6 forwarding. here is my bt0 config

Link encap:UNSPEC  HWaddr XX-XX-XX..............
          inet6 addr: fe80::XXX:XXX:XXXX:9daf/64 Scope:Link
          inet6 addr: 2007:xxxx:xxxx::1/64 Scope:Global

You are able to ping the nRF52 device from the RPi? Do you have a IPv6 network between the PC and the RPi?

You need to make sure that your router support IPv6 and that this is enabled. If you want to connect to the device from remote, you also need IPv6 support from your ISP. It is also possible to setup an IPv6 over IPv4 tunnel, to be able to communicate with the device without hardware support for IPv6.
