Connect Arduino Due with HC 06 Bluetooth Module

Last post (direct to Arduino-er: Test HC-06 Bluetooth Module with Android BluetoothChat) show how to use Android Bluetooth Chat test app to talk with standalone HC-06. This post show how to connect Arduino Due to HC-06 via Serial 3, to receive data from Android and echo back to Android, and also send to Serial port for monitoring.


Connection between Arduino Due and HC-06:
Serial (Tx/Rx) communicate to PC via USB
Serial3 (Tx3/Rx3) connect to HC-06
HC-06 Rx - Due Tx3
HC-06 Tx - Due Rx3
HC-06 GND - Due GND
HC-06 VCC - Due 3.3V

*/
#define HC06 Serial3

void setup()
{
 delay(1000);
 Serial.begin(9600);
 HC06.begin(9600);
 
 Serial.write(" Test Start ");
}

void loop()
{
 while(HC06.available())
 {
 char data = HC06.read();
 Serial.write(data);
 HC06.write(data);

Getting Started with Intel Edison Sensors Actuators Bluetooth and Wi Fi on the Tiny Atom Powered Linux Module

Getting Started with Intel Edison: Sensors, Actuators, Bluetooth, and Wi-Fi on the Tiny Atom-Powered Linux Module (Make : Technology on Your Time)

The Intel Edison is a crowning achievement of Intels adaptation of its technology into maker-friendly products. Theyve packed the dual-core power of the Atom CPU, combined it with a sideboard microcontroller brain, and added in Wi-Fi, Bluetooth Low Energy, and a generous amount of RAM (1GB) and flash storage (4GB). This book, written by Stephanie Moyerman, a research scientist with Intels Smart Device Innovation Team, teaches you everything you need to know to get started making things with Edison, the compact and powerful Internet of Things platform.

Projects and tutorials include:

• Controlling devices over Bluetooth
• Using Python and Arduino programming environments on Edison
• Tracking objects with a webcam and OpenCV
• Responding to voice commands and talking back
• Using and configuring Linux on Edison

Adafruit nRF8001 Bluetooth LE

Adafruit nRF8001 library for Arduino


adafruit/Adafruit_nRF8001 is driver and example code for Adafruits nRF8001 Bluetooth Low Energy Breakout.


PINOUT

(The Fritzing part of Adafruit nRF8001 can be download HERE)

The pin locations are defined in ble_system.h, the supported systems are defined in hal_aci_tl.cpp. The following pinout is used by default for the Arduino Uno:

SCK -> Pin 13
MISO -> Pin 12
MOSI -> Pin 11
REQ -> Pin 10
RDY -> Pin 2 (HW interrupt)
ACT -> Not connected
RST -> Pin 9
3V0 - > Not connected
GND -> GND
VIN -> 5V
RDY must be on pin 2 since this pin requires a HW interrupt.

3V0 is an optional pin that exposes the output of the on-board 3.3V regulator. You can use this to supply 3.3V to other peripherals, but normally it will be left unconnected.

ACT is not currently used in any of the existing examples, and can be left unconnected if necessary.

Android BluetoothChat example link with HC 05 Bluetooth

This example show to import and modify Android BluetoothChat example, to link with low-cost Bluetooth HC-05.

reference:
- First test HC-05 Bluetooth Module
- AT Command mode of HC-05

We need a FTDI USB-to-Serial adapter to connect PC/USB and HC-05 Bluetooth, and use Arduino IDEs Serial Monitor as terminal, to talk with Android running modified BluetoothChat example.


This video show how to import BluetoothChat example in Android Studio, and edit BluetoothChatService.java to change MY_UUID_SECURE to UUID.fromString("00001101-0000-1000-8000-00805F9B34FB").

~ reference http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html, If you are connecting to a Bluetooth serial board then try using the well-known SPP UUID 00001101-0000-1000-8000-00805F9B34FB.


This video show how it run on Android device, and talk to PC running Arduino IDEs Serial Monitor, via FTDI + HC-05.

In my on-hand HC-05 sample, it set as slave role and 9600, 0, 0, PIN="1234" by default, I have not change any setting.
