The nRF51822 is a multi-protocol SoC ideally suited for Bluetooth® low energy and 2.4GHz ultra low-power wireless applications from Nordic Semiconductor. The nRF51822 is built around a 32-bit ARM® Cortex™ M0 CPU with 256kB flash + 16kB RAM. The embedded 2.4GHz transceiver supports Bluetooth low energy as well as 2.4GHz operation.

Nordic's development kit contains two different boards:

  • pca10000: a USB-dongle containing the nRF51822 and a RGB-Led
  • pca10005: two a basic nRF51822 boards making the MCU pins available

While the pca10000 contains an on-board J-Link debugger, the pca10005 boards have to be flashed/debugged using the (included) external J-Link device.

Flashing the Device:

The nRF51822 PC10000 board is shipped with an on-board JLink debugger. However the PC10004/5 board uses an external flash tool as seen in the Image above. Under Linux, the easiest way flashing the nRF51822 is using the JLink tool(version >4.85) from Segger.

To interact with the board just start the tool using the following command: # JLinkExe -device nrf51822

For RIOT itself there is a Flash-Script available. When using any of the Examples type in the following command: # Make -B clean flash
