how can i acces the nrf51(nrf51422) dk from the internet using copper coap?

[Liverpool007]

I have set up raspberry pi 3 as a border router and programmed the the nrf51422 using the iot_ipv6_coap_server_pca10028 and could successfully switch on and off led3 and led4 using copper coap client on a local area network.

is it the client ipv6 address or something else?i tried the the ipv6 client addresse and could score only 4/20 on ipv6-test

It should be the IPv6 address after address in the example configurations. I'm not sure why you don't get more than 4/20.

i am getting an error ip is not icmp pingable.please make sure icmp is not blocked.if ou are blocking icmp please allow xx.xxx.x.xx through your firewall.

[Petter Myhre]

Hmm. OK. Then I think you must enable the ping response feature in your router.
