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.

yes i added prefix and started radvd service also but device is not pinging from internet.

Here is my configuration

interface eth0
{
AdvSendAdvert on;
prefix 2005:abc::/64 {
AdvOnLink on;
AdvAutonomous on; AdvRouterAddr on;
};
route ::/0
{
};
};

interface bt0
{
AdvSendAdvert on;
prefix 2001:db8::/64
{
AdvOnLink off;
AdvAutonomous on;
AdvRouterAddr on;
};
};

And also i added these from command line

ifconfig bt0 add 2001:db8
ifconfig eth0 add 2004:abc::1/64::1/64
service radvd restart

Now able to ping device from my pc and by router but not by internet.

Kindly suggest me , where i am missing.

It could be that your router doesn't support protocol 41. Have you tried to sniff? I would try to use wireshark and sniff the et0 interface. Then you should see packets with destination address 192.88.99.1 when you ping ipv6.google.com.
