Since the IoT SDK is not support the IPSP Router role.
Is that mean the nRF51822 can't been used by other MCU which is running Contiki to become a Edge Router?
There are many links across the Internet to app note nAN-29 ( nRF51 Development with GCC and Eclipse ). In fact, I remember seeing a link to it on the Nordic website just...
