arduino uno 逐个命令配置HC-05蓝牙模块

以下代码可以使用IDE自带的串口工具单个命令配置

使用Uno和HC-05实验

 

#include<SoftwareSerial.h>

SoftwareSerialbluetooth(12, 13); //RX,TX

String at ="";

void setup() {

  // put your setup code here, to run once:

  Serial.begin(9600);

  while (!Serial) {

    ;

  }

  Serial.println("Goodnight moon!");

  bluetooth.begin(38400);

  bluetooth.println("Hello, world?");

}

 

void loop() {

  // put your main code here, to runrepeatedly:

  if (bluetooth.available())

    Serial.write(bluetooth.read());

  while (Serial.available() > 0)

  {

    at += char(Serial.read());

    delay(2);

  }

  if (at.length() > 0)

  {

    bluetooth.println( at);

    at = "";

  }

}
