The Nordic Semiconductor nRF51-DK Development kit is designed for Bluetooth Smart, ANT and other 2.4GHz wireless applications. The development platform is based on the nRF51 series of wireless System-on-Chips and supports both the nRF51822 and nRF51422 devices.
The Over the Air (OTA) Device Firmware Upgrade (DFU) means the user can release firmware updates to the cloud which can then be programmed via a smart phone, PC or tablet to the nRF51 series device. The Development Kit supports the standard Nordic Software Development Tool-chain using Keil, IAR and GCC and for rapid prototyping the ARM mbed tool-chain. Additionally the nRF51 kit can be used as Bluetooth Smart packet sniffer using Nordic nRF Sniffer software which will allow you to capture and analyse the data.
