How to get the nrf DK device to be available on the internet?

[danielkelly]

I am testing nrf5 IoT tcp client example. (in \nrf5_iot\examples\iot\tcp\client)

1. DK side:

IP:2004::213:ddff:fe4c:6032

run as client.

2.6lowpan border router (raspberry PI3)

interface bt0 eth0

bt0:

IP:2004::ba27:ebff:fe15:ae01

run as server, app source code:

 import socket
    import struct
    
    SERVER_ADDR = '2004::ba27:ebff:fe15:ae01'
    SERVER_PORT = 9000
    sock = socket.socket(socket.AF_INET6, socket.SOCK_STREAM)
    server_addr = (SERVER_ADDR, SERVER_PORT, 0, 0)
    sock.bind(server_addr)
    sock.listen(1)
    client, addr = sock.accept()
    print 'Connected'
    while 1:
        recv_data = client.recv(128)
        recv_len = len(recv_data)
        if recv_len >= 8:
            rx_sequence_number = 0
            rx_sequence_number = struct.unpack("!I", recv_data[:4])[0]
            data = struct.pack("!i", (rx_sequence_number)
            print(data)
            data +=  'Pong'
            client.send(data)
    sock.close()
    del sock

Now, the client and server sides work well.

But how to communicate with nrf DK(client) by using eth0?

Further more, how to get the nrf DK device to be available on the internet? need to bridge bt0 and eth0 ?

thanks!

Could you please explain a bit more about what you want to do, and what you have actually done? Do you have native IPv6 connectivity or are you setting up a simulated global network? Have you enabled IPv6 forwarding? How have you setup RADVD? Are you able to ping the nRF5 with link local address (ping6 –I bt0 fe80::211:22FF:FE33:4455)? Are you able to ping the nRF5 with global address (ping6 2005::211:22FF:FE33:4455)? Are you able to IPv6 ping the ubuntu PC from the RPi? Are you able to IPv6 ping the eth0 interface on the RPi from the ubuntu PC? Are you able to IPv6 ping the bt0 interface on the RPI from the ubunti PC? Please edit your question and explain what you have done.
