I gave this now a try, how can I see the issue now?

I see on output:

recv_raw_icmp[fe80:0:41:c863:cdab:ffff:bbaa:aaaa%lowpan0->?]

this address doesn't exist in my network.

I can also upload wpan wireshark logs and lowpan wireshark logs, if you
like.

In sockdebug I changed also "const char* src_string =" to one of my
lowpan addresses. Simon are you still here to debug this issue with me?
