I'm concentrating on a work about connecting nrf51-dk device in the sensor node end implementing COAP server, ble enabled rapsberrypi and COAP client using Copper. To check connection, I followed nrf sdk 0.9 user guide and I got stucked with at some point. When copper ping to the nrf-dk device which get a global ipv6 address, it doesn't get ping response. when I ping in the raspberry pi to the nrf-dk, it work. I think on the external network, it doesn't know about the nrf51-dk network address, So I must implement the raspberry-pi as a real router using some method as well as nrf51sdk usr guide implementation. Is my suggestion right?? If so, how I make raspberry-pi forward packet to external network?? plz help me!!
