How to setup：

1. Download and install ICBlock Application
2. Setup and Download nordic nRF51822 SDK  follow below steps.

 Windows

Step 1: Go to Nordic’s nRF51822 download page

• Nordic nRF51822 Download
  

Step 2: Get nRF51822 SDK

• Click nRF51-SDK-zip to download
  
• Please refer to “How To Download nRF51 SDK v7.x.x” if you want to use SDK 7.x.x version.
  
  

Step 3: Get nRF51822 SoftDevice (S110)

• Click S110-SD-v7
  
• Note: current SDK requires S110 v7 to compile
  
  

Step 4: Get nRF51822 Tools

Note: See OSX/Linux session below if you are not using Windows.

1. Download the nRFTools_6_1_0_Installer.exe
   
2. Run the .exe and install it
3. We just need the mergehex.exe and it should be installed by default at
   C:\Program Files (x86)\Nordic Semiconductor\nrf51\bin\

Step 5: Get ARM GCC

• Download ARM GCC
  https://launchpadlibrarian.net/177524899/gcc-arm-none-eabi-4_8-2014q2-20140609-win32.zip

Step 6: Get GNU Make utility

1. Download GNU Make
   http://iweb.dl.sourceforge.net/project/gnuwin32/make/3.81/make-3.81-bin.zip

2. Download GNU dependency files
   http://iweb.dl.sourceforge.net/project/gnuwin32/make/3.81/make-3.81-dep.zip
   Note: For Windows, the make.exe needs some DLLs to run, these are in make-3.81-dep, put them into a same folder

Step 7: Putting all tools into a folder

• Unzip all tools to a folder, for example “D:\nRF51822”, we will use this as our development folder, and you should see the follow structure
  

Step 8: Modify Makefiles

• In this folder, modify Makefile.windows
  
  D:\nRF51822\nrf51_sdk_v6_1_0_b2ec2e6\nrf51822\Source\templates\gcc
  
  With the follow code:

• modify Makefile.common, add SDK_PATH and SDK_SOURCE_PATH:

Step 9: Compile Heart Rate Sensor (HRS) example

1. Start a Command Prompt:
2. Go to this folder:
   D:\nRF51822\nrf51_sdk_v6_1_0_b2ec2e6\nrf51822\Board\nrf6310\s110\ble_app_hrs\gcc
3. In command prompt, run:
   D:\nRF51822\make-3.81\make.exe -f ble_app_hrs.Makefile
4. The firmware file (.hex) will be created inside the _build folder

Step 10: Merge HRS with SoftDevice Note: See OSX/Linux session below if you are not using Windows.

1. Run merge tool:
   D:\nRF51822\mergehex.exe –merge D:\nRF51822\s110_nrf51822_7.0.0_softdevice.hex _build\ble_app_hrs_s110_xxaa.hex –output hrs.hex
2. Sample screen output:

Step 11: Load the compiled firmware

1. Connect your nRF51822 board to an USB port
2. Drag and drop the hrs.hex to the MSD drive, e.g. E:

**You should be able to do this if you follow the Getting Started – nRF51822

Step 12: Test it with Nordic nRF ToolBox App

1. Go to App Store and download “nRF ToolBox”
2. Run “HRM” and connect to the development board

Mac OSX

Step 1: Click here to download ARM-GCC for MAC application, unzip and install.

Step 2: The mergehex.exe is only for Windows platform. Use srec_cat instead on Mac OSX.

Step 3: Install brew from Terminal

$ ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

Step 4: Install srecord using brew from Terminal

$ brew install srecord

Step 5: Merge using srec_cat command

$ sreccat s110nrf518227.0.0softdevice.hex -intel bleapphrss110xxaa.hex -intel -o hrs.hex -intel –line-length=44

Linux

The mergehex.exe is only for Windows platform. Use srec_cat instead on Linux.

Step 1: Install srecord

$ sudo apt-get install srecord

Step 2: Merge using srec_cat command

$ sreccat s110nrf518227.0.0softdevice.hex -intel bleapphrss110xxaa.hex -intel -o hrs.hex -intel –line-length=44
