Setting up IPv6 over BLE using nRF52 Series and Contiki OS

[akash naidu]

Hi All

Currently i am working on IPV6 over BLE with contiki oS.

For that i am following link ...

https://devzone.nordicsemi.com/b/blog/posts/setting-up-ipv6-over-ble-using-nrf52-series-and-com

I have successfully established the connection with nRF52 DK.

After that If i ping to the nrf52 dk, i am getting following response.

ping6: Warning: source address might be selected on device other than bt0.
PING fe80::217:1Bff:fe61:F143(fe80::217:1bff:fe61:f143) from :: bt0: 56 data bytes
From fe80::b0c0:90ff:feb4:151c%bt0: icmp_seq=1 Destination unreachable: Address unreachable

From fe80::b0c0:90ff:feb4:151c%bt0: icmp_seq=3 Destination unreachable: Address unreachable

But if i ping to local address, i am getting proper response.

PING fe80::b0c0:90ff:feb4:151c%bt0(fe80::b0c0:90ff:feb4:151c%bt0) 56 data bytes

64 bytes from fe80::b0c0:90ff:feb4:151c%bt0: icmp_seq=4 ttl=64 time=0.108 ms

So, please help me how to resolve this issue.

Thanks in advance

Hello Akash,

Could you post the output from the steps before ping? All the inputs and all the outputs?

Hi Edvin,

Before posting my output, i am using Ubuntu(18.10) version 4.18.0-10-generic .

I am posting from Making IPV6 connection, because Hello world is printing on console.

sudo hcitool lescan:

00:17:1B:61:F1:43 Contiki nRF52dk(This is my nRF52 DK address)

Now LED2 is stable, means connection has been established.Then i am pinging(ping6 addr)

Best Regards

Hello Akash,

I assume that the link you were supposed to post was this one? (your link is broken).

What did you program on your DK? And which DK do you use? nRF52832, nRF51xxx or nRF52840?

Best regards,

Edvin

I have flashed soft device as well as hello world program.

I am using nRF52832 DK.
