BT -----> Arduino ----------------- VCC ----> +5V GND ----> GND TX -----> D0 RX RX -----> D1 TX
- chargez le programme BluetoothEcho.ino sur l'Arduino en débranchant le VCC du module BT
- débranchez l'Arduino
- rebranchez le VCC du module BT sur le 5V de l'Arduino : la led rouge du module clignote
- rebranchez l'Arduino sur son l'alimentation (ou l'USB)
- appariez le device BT (le nom par défaut est "linvor") sur votre téléphone Android : la clé par défaut est "1234" : la led rouge du module est fixe (on)
- utilisez l'application BlueTerm disponible sur l'Android Market Google Play
- changez la diode embarquée (13) au moyen des touches 'l' et 'h'
// BluetoothEcho.ino char val; // variable to receive data from the serial port int ledpin = 13; // LED connected to pin 13 (on-board LED) void setup() { pinMode(ledpin, OUTPUT); // pin 13 (on-board LED) as OUTPUT Serial.begin(9600); // start serial communication at 9600bps // the default baud rate for http://dx.com/p/jy-mcu-arduino-bluetooth-wireless-serial-port-module-104299 } void loop() { if( Serial.available()) // if data is available to read { val = Serial.read(); // read it and store it in 'val' } if( val == 'h' ) // if 'l' was received { digitalWrite(ledpin, HIGH); // turn ON the LED Serial.write('H'); } else if( val == 'l' ) // if 'l' was received { digitalWrite(ledpin, LOW); // turn it OFF Serial.write('L'); } else if(val>=32 && val <127) { // otherwise echo the read char Serial.write(val); } val=0; delay(100); // wait 100ms for next reading }

// @from http://club.dx.com/forums/Forums.dx/threadid.1166641 // @see http://arduino.cc/en/Reference/SoftwareSerial // use with Blueterm android app http://pymasde.es/blueterm/ #include <SoftwareSerial.h> SoftwareSerial mySerial(10, 11); // RX, TX void setup() { Serial.begin(9600); Serial.println("ready!"); mySerial.begin(9600); mySerial.println("READY!"); } void loop() { if (mySerial.available()){ Serial.write(mySerial.read()); } if (Serial.available()){ mySerial.write(Serial.read()); } }
Utilisation avancé
- To initlalize the BT module, send it the following AT commands: AT+PIN1234 <cr> AT+NAMEdongle <cr> AT+BAUD4 <cr>. The last command will set the baud rate to 9600.
- Then on the PC, connect to a new Bluetooth device, use the same PIN number as above, make note of which serial (COM) port it maps to and then use Putty (Windows) or screen (Linux) to test!
