Programming the SoftDevice

If your application uses Bluetooth or ANTâ„¢, you must program a SoftDevice in addition to the application.

There are several ways to program the SoftDevice to the board. You can program the SoftDevice directly from Keil, use the command line tool nrfjprog (part of the nRF5x Command Line Tools), or use the Windows application nRFgo Studio.

The Bluetooth SoftDevices are included in the nRF5 SDK and can be found in the SDK_dir\components\softdevice\ folder. Check SoftDevices for information about which SoftDevice is compatible with your development board.

Note: The nRF5 SDK does not contain ANT SoftDevices. You can download them from The nRF5 SDK does not provide Targets to program ANT SoftDevices. Therefore, you must use nrfjprog or nRFgo Studio to program them.
