 #ble_a_Hello_World_Program : Setup
 
-The Hello_World_Program uses BLE to send a string, "Hello World, works", from the Arduino board to the peer Bluetooth low energy device.
-The peer can be the nRF UART app running on iOS or Android or PC (See the Master Emulator -> Examples -> nRFUART, this is installed as part of the Master control panel Windows tool)

-The Arduino IDE or equivalent and Arduino board are working. You can use the "Getting Started" pages on http://arduino.cc to get help and to troubleshoot.
-Once you have confirmed that the Aduino board and IDE are working:
-* Connect the nRF8001 to the Arduino (using either a shield or with direct wiring)
-* Open the ble_a_Hello_World_Program sketch (.ino file) in the IDE or equivalent
-* Verify that the pin connections are correct for the shield in the sketch.
-This will vary depending on the shield that you use.

-* After the board has been identified by the software, click the "Device Discovery" button
-* Click on the Device "Hello" -> then click Select Device.
-* You will see a new screen
-* Then click the "Service Discovery button"
-* Wait for the Service Discovery to complete
-* Click -> Enable Services to configure the BLE Service used for Hello World
-* Click on the entry that says UART RX
