Nrf51 IOT TCP Client testing

[Fab1223]

Hi All,

we have PCA10028 v1.10 nordic development board, i tested the normal ping from local ip and global ip of device from my linux PC by flashing tcp client iot application , which is working fine.

but data transmission between client and server is not working , basically server is not connecting to client by using phyton server code.

Here my server ip config.

bt0 Link encap:UNSPEC HWaddr 68-94-23-FF-FE- 8A-45-50-00-00-00-00-00-00-00-00
inet6 addr: fe80::6a94:23ff:fe8a:4550/64 Scope:Link inet6 addr: 2001:db8::9586:dfba:1684:a501/64 Scope:Global inet6 addr: 2001:db8::1/64 Scope:Global inet6 addr: 2001:db8::6a94:23ff:fe8a:4550/64 Scope:Global UP POINTOPOINT RUNNING MTU:1280 Metric:1 RX packets:630 errors:0 dropped:0 overruns:0 frame:0 TX packets:1019 errors:579 dropped:120 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:32434 (32.4 KB) TX bytes:70649 (70.6 KB)

So i changed the ip in server with my pc ip (2001:db8::6a94:23ff:fe8a:4550). but connection is not happened.

Kindly let me know what is the issue.

and also i bit confused with how to access device from internet. kindly let us know.

Regards Punith

Hi,

It seems you have native IPv6 connectivity. What ipv6 address and prefix is your router getting?

Have you set up RADVD so that the nRF51 DK gets the correct prefix? It should be something like:

interface bt0
{
	AdvSendAdvert on;
	prefix 2002:c213:5692::1/64
    {
	    AdvOnLink off;
    };
};

(This is from my 6to4 tunneling setup)

You also need to add the prefix to the bt0 interface and restart radvd:

ifconfig bt0 add 2002:c213:5692::1/64
service radvd restart

You can try to ping the nRF51 DK from the internet here.
