Description

HC-05 Wireless Bluetooth Transceiver Module RS232/TTL to UART converter
Brand : Unbranded NEW
Module size: 3.7cm width: 1.6cm
Introduction:
HC-05 Bluetooth module with Clear button
1 Input voltage: 3.6V – 6V, prohibit more than 7V
2 The power anti-reverse, reverse module does not work
3 Leads to 6 feet: EN / VCC / GND / RXD / TXD / STATE (Bluetooth status leads to the foot, unconnected output low, output high after the connection)
4. With a Connection Status indicators , LED flash means no Bluetooth connectivity; LED slow flash that enter the AT command mode
5. On-board 3.3V regulator chip, the input voltage DC 3.6V-6V; when unpaired, current about 30mA (because LED lights flashing, current state of change ); After successful pairing, current of about 10mA
6. interface output 3.3V, can be directly connected to various microcontroller (Arduino / 51 / AVR / PIC / ARM / MSP430 etc.), 5V microcontroller can also be directly connected. Directly connected to the microcontroller serial port, not through MAX232 chip!
7. The open area effective transmission distance of 10 meters
8. You can switch the master and slave mode via AT command
9. The module defaults to 9600, the default pairing password is 1234, the default name for the HC-05
10. With transparent shrink tube to protect

AT Comment:

//Arduino <===> HC-05
// 5V ==> 5V
// GND ==> GND
// TX ==> TX
// RX ==> TX

#include <SoftwareSerial.h>
SoftwareSerial HC(10,11); //TX=11,RX=10
void setup() {
Serial.begin(9600);
HC.begin(38400);
}

void loop() {
if(Serial.available() > 0){
String x = Serial.readString();
HC.println(x);
}
if(HC.available() > 0){
String x = HC.readString();
Serial.println(x);
}
}
