2.4 How to compile and program ble_app_hrs

a) Program S110 nRF51822 SoftDevice (Bluetooth protocol stack):

Select nRF51 Programming > Program SoftDevice> Browse (choose corresponding

Bluetooth protocol stack) > Program (wait for completing Bluetooth protocol stack

programming).

Notes: The protocol stack file we used here, s110_nrf51822_6.0.0_softdevice.hex, is

decompressed from \Software\s110_nrf51822_6.0.0.zip.

b) Program upper application.

c) Enter <KEIL path> \ARM\Device\Nordic\nrf51822\Board\pca10001\s110\ble_app_hrs\arm

or <code path>\BLE4.0\nrf51822\Board\pca10001\s110\ble_app_hrs\arm.

And then, open Keil project file.

After completing program compiling and download, you will find that all the configurations

are restored to factory default settings, since ble_app_hrs is the very default program

preinstalled by the factory. For more information about testing methods, please refer to the

section “Out of box audit”.
