Bluetooth 4.0 BLE Gateway Shield is an addon that can turn pcDuino8 Uno into a Bluetooth 4.0 BLE gateway. It is using  Nordic nRF51422 chipset and  Arduino compatible. User have the flexibility to what serial ports (soft serial port or hard serial port on pcDuino) can be used to talk to the gateway by installing jumpers.  User can also reflash the firmware of the nRF51422 chipset using the on-board debug headers. For example, user can choose to flash the chipset with [http://linksprite.com/wiki/index.php5?title=Mbed_BLE_Sensors_Tag  MBED BLE and S110 protocol].

== Firmware flash ==
 
  
All BLE gateway shield comes with a gateway firmware pre-installed.
 
 
If we need to reinstall the firmware to the bluetooth shield. Please follow the following steps:
 
 
To flash the firmware the bluetooth chipset, we use Jlink to burn the firmware.
 
 
1)Preparation Tool
 
 
*Jlink JTAG x 1
 
*Jumper wires  x 4
 
*BLE Gateway Shield x 1
 
 
2)Firmware burning
 
 
Jlink pins definition:

Connecting Jlink JTAG’s VCC, GND, SWIO, SWCLK to corresponding pins of BLE Gateway Shield (some jlink JTAG DOESN’T have power output, we need provide power separately) .

    Serial.write(outbuff[x]); 
 
  }
 
  }
 
 
( 3 ) Steps and results
 
 
After we finished the firmware burn, open serial tool of Arduino IDE.
 
 
Install BLE controller APP on  Android phone. User Light Blue on iPhone.
 
 
In this tutorial, we will use  Android phone for example, open BLE Controller, choose Simple Chat, then connect the gateway, we can send data now.

Introduction

Bluetooth 4.0 BLE Shield is an addon that can turn pcDuino8 Uno into a Bluetooth 4.0 BLE Shield. It is using Nordic nRF51422 chipset and Arduino compatible. User have the flexibility to what serial ports (soft serial port or hard serial port on pcDuino) can be used to talk to the BLE Shield by installing jumpers. User can also reflash the firmware of the nRF51422 chipset using the on-board debug headers. For example, user can choose to flash the chipset with MBED BLE and S110 protocol.
