Tip

When using this board with RIOT, set the BOARD variable to nrf51dk in your Makefile. If you follow the standard RIOT project structure, your Makefile should look like this:

./Makefile

# name of your application
APPLICATION = hello-world

# Change this to your board if you want to build for a different board
BOARD ?= nrf51dk

# This has to be the absolute path to the RIOT base directory:
RIOTBASE ?= $(CURDIR)/RIOT

include $(RIOTBASE)/Makefile.include

Support for the Nordic nRF51DK Development Kit

Overview

The nRF51 DK is a low-cost, versatile single-board development kit for Bluetooth low energy, ANT and 2.4GHz proprietary applications using the nRF51 Series SoC.

Flashing the Device

The nRF51DK board is shipped with an on-board JLink debugger that doesn’t work well with UART: the shell is only working on RX but not TX.

Thus, we recommend to update the flasher ship with DAPLink as described here:

1. Download and extract this release package
2. While holding down the boards reset button, connect the boards USB debug port to the computer. It should enumerate as BOOTLOADER
3. Using a filesystem browser, drag-n-drop the firmware 0251_sam3u2c_mkit_dk_dongle_nrf5x_0x5000.bin file to the BOOTLOADER folder
4. Power-cycle the board, a new DAPLink mount point should appear

The programmer used to flash this board is OpenOCD.

To flash the board, use the following command:

BOARD=nrf51dk make flash

from any application directory.
