Android BluetoothChat connect to Arduino Uno HC 05
Android BluetoothChat connect to Arduino Uno HC 05
Last example show "Android BluetoothChat example link with HC-05 Bluetooth", to connect to PC via FTDI adapter. Here is another example - Arduino UNO + HC-05 to echo received data back to the sender.
For my on-hand HC-05 sample, it set as slave role and 9600, 0, 0, PIN="1234" by default. So it can be used in this example without any extra setting.
Connection between UNO and HC-05
HC-05 Rx - Uno Tx (1)
HC-05 Tx - Uno Rx (0)
HC-05 GND - Uno GND
HC-05 VCC - Uno 5V
(My HC-05 marked "Power: 3.6V-6V", refer here, make sure your HC-05 can work on 5V.)
Uno_Serial_echo.ino
/*
Arduino Uno + HC-05 (Bluetooth) - echo bluetooth data
Serial (Tx/Rx) communicate to HC-05
HC-05 Rx - Uno Tx (1)
HC-05 Tx - Uno Rx (0)
HC-05 GND - Uno GND
HC-05 VCC - Uno 5V
*/
void setup()
{
delay(1000);
Serial.begin(9600);
}
void loop()
{
while(Serial.available())
{
char data = Serial.read();
Serial.write(data);
}
}
This video show how Android BluetoothChat example link with Arduino UNO + HC-05. For the Android BluetoothChat example, refer last post.
