BLEduino has been released for almost half a month, and we also received tremendous inquiries from distributors and retailers. As a Bluetooth module,it can be applied into a variety of terminal devices through the mobile APP control, so in order to give more guide to client’s using method, besides the release of BLE APP for Android and IOS, we also launch the BLEduino User Guide , which is estimated to be helpful in BLE operations. The BLEduino board is first of its kind in integrating BT 4.0(BLE) module into Arduino Uno, making it an ideal prototyping platform for both software and hardware developers to go wireless. You will be able to develop your own smart bracelet, smart pedometer and more. Through the low- power Bluetooth 4.0 technology, real-time low energy communication  can be made really easy. 

Hardware:

1. Android phones with system 4.3 and Bluetooth 4.0
2. USB Cable
3. BLE Adapter
4. BLEduino Mainboard

Software

1. Arduino IDE
2. APP Arduino Controller
3. Serial port debugging software sscom32E 

Part 1  BLEduino USB Programming

Step 1  Hardware operation

Connect the BLEduino to the PC via USB cable

Step 2   Install the driver

When connected to the computer, the computer will prompt to install driver, follow the prompts to install 

it( the way to install the driver is the same with Arduino UNO and the Driver Name is TI CC2540 Drivers).

Step3 Programming

1. Open the program we need to upload with Arduino IDE, and then choose the Board of Arduino UNO, in addition, the corresponding Serial Port.

2.Compiling sketch until Done compiling appears

3.Uploading sketch until Done uploading appears(when uploading, TX, RX LED will be blinking)

Note: When USB programming, BLEduino had to disconnect with other Bluetooth, and the LINK LED will be twinkling when the Bluetooth is disconnected. 

Part 2  BLEduino Wireless Programming

Step 1  Hardware preparation

Prepared BLEduino, BLE Adapter and USB Cable

Step 2 Host searched slave and then connected to Slave

Connect the BLE Adapter Defaulted as host BLEduino Defaulted as Slaveto the computer.Via serial port debugging software,

 open the serial port of host and Slave,and then host send AT SCAN+ Enter to search Slave,just as the following screenshot shows

After the host searched the Slave, the host send AT CON 1 + Enter to connect the Slave, and the Slave can get the host Return Value 

of connected if connection is successful,at the same time, BLEduino link LED will stop blinking and be always lit.

Step 3  BLE Adapter(host) Programming for BLEduino Slave 

After the host connected to Slave，open the program need to be uploaded via Arduino IDE, choose the corresponding Board of UNO，choose the BLE Adapter (host) Serial Port, and then the specific operating steps are the same with USB programming, which has been introduced in detail previously.

Part 3 Mobile APP Control BLEduino MCU IO Mode

 Step 1 Firmware Programming

Download Firmware AndroidIOControl and then open it Via Arduino IDE program the firmware to BLEduino MCU with USB, and the specific operation steps are the same with previous USB programming.

Step 2 Mobile phone connected to BLEduino(had to be set to Slave)

1. Open the Phone APP operating interface

2. Click Scan to search Slave BLEduino as below

3. After searching the Slave  ELF-USB,click ELF-USB to connect it, when it succeeded, Link LED will be always lit and phone App will prompt“connection successful”

Step 3 Mobile Control BLEduino MCU IO

Note: After the connection between BLEduino and mobile, if you want to perform the MCU read and write operations, 

MCU has to be reset firstly(pressing the reset button is ok)

1. Firstly is Read Control to BLEduino MCU IO. On the left side of the App UI, 

modify the IO switches which mean to control to I mode, then press the Read button on the right, 

you can read the current MCU IO status, such as the following examples. (Operation IO: 2, 3, 4, 5 6 7)

2. When press the Read, the IO value is low (0). This is the complete simple Read operation.

3.    Below is the Write control for BLEduino MCU IO. On the left side of the App UI, 

modify the IO switches which mean to control to O mode, such as the following examples. (Operation IO: 13)

4.    When press the Write button, Write out IO13 value as high 

(1), and the D13 LED of  the BLEduino mainboard would be lit, but if Write out IO13 value as low (0), the D13 LED    would be off.
