Can not ping nRF52DK from linux laptop

[pashka]

Hello,

I got TCP Server example working on nRF52DK with Raspberry Pi. I set everything up and can ping global addresses of DK on all interfaces (wlan0, eth0 and bt0) from raspberry pi. But for some reason I can not ping same addresses from my laptop.

ping commands that I use look like this:

ping6 -I bt0 2001:db8::235:eeff:fe82:7d97
ping6 -I eth0 2001:db8::235:eeff:fe82:7d97
ping6 -I wlan0 2001:db8::235:eeff:fe82:7d97

I set prefix 2001:db8::/64 on all interfaces. All of the above commands work from RasPi - I got packages sent and recieved, 0% package loss. From laptop - all of the commands result in 100% package loss. No packages recieved.

RasPi is connected with ethernet cable to wifi router. RasPi also has wifi dongle. What can be wrong? Do I need some special setup on laptop?

Hey pashka, could you please tell me how did you find those IP addresses. I tried running commands like 'ifconfig' and 'nmap', they gave me nothing. Are you suppose to connect to them using some kind of code or they automatically connect. Please let me know, I really them to connect. Thanks in advance.
