I'm using the IPv6 stack.

Thanks! I can't see any obvious issues in the capture file. We know there is an issue when using the lwIP stack wrt loosing the prefix, but this is only after a connection has been disconnected and re-established without a reset. So, are you using the lwIP or the IPv6 stack (two different folders in the SDK project folder)?

Capture file attached above (captured from bt0 interface of raspi)

Sample source not modified (though I have moved it and reworked paths in make file, but no source changes).

Ping response on global interface at #4,#6,#8 Coap request #13, response on link local address at #14 ICMP error notification from bt0 link local address at #15

Hi, I'm not able to reproduce this. Is the example modified in any way? Can you please upload the wireshark logs here (go to file->save as), including the router advertisement and ICMP packets. Thanks.
