(nRF51822 & nRF51422 & nRF52832 & nRF51802)
Now both #nRF51 & #nRF52 Support IPv6 Over Bluetooth Smart.#nRF5SDK
Quoted from Nordic: http://www.nordicsemi.com/eng/Products/Bluetooth-Smart-Bluetooth-low-energy/nRF5-SDK-for-IoT
This SDK is a IPv6 capable Bluetooth® Smart software stack that provides drivers, libraries, examples, and APIs for nRF52 Series devices. It includes an IPv6 over Bluetooth Smart adaptation layer (6LoWPAN) and a complete Internet Protocol Suite including IPv6, ICMP, UDP, TCP, DTLS, TLS, CoAP and MQTT. It brings native IPv6 support to Bluetooth Smart applications, letting them talk directly to cloud services and other connected ‘things’ over IP-based networks.
The SDK includes examples that configure the nRF52 device as a Bluetooth Smart 6LoWPAN node and that interface with the IP layers at transport level (UDP amd TCP) and with security (DTLS and TLS), to the application level CoAP and MQTT and LWM2M. Examples of how to connect to cloud services is also included in the documentation. The SDK also includes an implementation to for over the air upgrade for Bluetooth Smart IPv6 nodes over IP using the trivial file transport protocol (TFTP).
As a router for development an off-the-shelf router running OpenWRT or a Raspberry Pi can be used. A solution for commissioning of Bluetooth Smart IPv6 nodes to a router with a mobile phone as a trusted third party is also included. Source code for the commissioning app and the needed OpenWRT daemon is also available. All this is described in the documentation.
The nRF5 IoT SDK documentation are available at our infocenter.
