Hello Arduino I'm not good at English
so i got problem configuring HC-05 shield...
https://www.itead.cc/wiki/BT_Shield_(Master_Slave)
This is description of BT shield
i upload this code to configure it
// Basic Bluetooth sketch HC-05_02_38400
// Connect the HC-05 module and communicate using the serial monitor
//
// The HC-05 defaults to commincation mode when first powered on.
// Needs to be placed in to AT mode
// After a factory reset the default baud rate for communication mode is 38400
//
//
// Pins
// BT VCC to Arduino 5V out.
// BT GND to GND
// BT RX to Arduino pin 3 (through a voltage divider)
// BT TX to Arduino pin 2 (no need voltage divider)
#include <SoftwareSerial.h>
SoftwareSerial BTserial(2,3); // RX | TX
// Connect the HC-05 TX to Arduino pin 2 RX.
// Connect the HC-05 RX to Arduino pin 3 TX through a voltage divider.
char c = ' ';
void setup()
{
// start th serial communication with the host computer
Serial.begin(9600);
Serial.println("Arduino with HC-05 is ready");
// start communication with the HC-05 using 38400
BTserial.begin(38400);
Serial.println("BTserial started at 38400");
}
void loop()
{
// Keep reading from HC-05 and send to Arduino Serial Monitor
if (BTserial.available())
{
c = BTserial.read();
Serial.write(c);
}
// Keep reading from Arduino Serial Monitor and send to HC-05
if (Serial.available())
{
c = Serial.read();
// mirror the commands back to the serial monitor
// makes it easy to follow the commands
Serial.write(c);
BTserial.write(c);
}
}
I tried this but nothing work
so I change 2 and 3 to 0 , 1
but nothing work either...
How should I make code and design shield to give AT-command?
please help me everyone :o
