Hi,
I am trying to run IPSP example from nRF Connect SDK 1.4.2 IPSP sample (v1.4.2\zephyr\samples\bluetooth\ipsp). The "ping6 -I bt0 ff02::1" command is working fine but when ping with global address (ping6 2001:db8::1) the address is not reachable. A tshark running listening to the interface is shows the following ouput.
1 0.000000000 2001:db8::2 → ff02::1:ff00:1 ICMPv6 88 Neighbor Solicitation for 2001:db8::1 from b8:27:eb:0e:08:ee

How can I debug the issue? No modifications from the example and using nRF52 DK, Linux kernel version is higher than 4.2 (Linux raspberrypi 5.4.79+) so the workaround CONFIG_NET_L2_BT_ZEP1656 has no effect.
