#include
SoftwareSerial BTSerial(10, 11); // RX | TX
void setup()

pinMode(9, OUTPUT); // this pin will pull the HC-05 pin 34 (key pin) HIGH to switch module to AT mode
digitalWrite(9, HIGH);
Serial.begin(9600);
Serial.println("Enter AT commands:");
BTSerial.begin(38400); // HC-05 default speed in AT command more

void loop()

// Keep reading from HC-05 and send to Arduino Serial Monitor
if (BTSerial.available())
Serial.write(BTSerial.read());
// Keep reading from Arduino Serial Monitor and send to HC-05
if (Serial.available())
BTSerial.write(Serial.read());

unity在安卓手机上使用蓝牙连接arduino蓝牙模块

unity在安卓手机上使用蓝牙连接arduino蓝牙模块想通过unity导出安卓项目 用手机蓝牙控制arduino蓝牙模块

参考技术A 我没用过unity，到在安卓手机通过蓝牙和arduino通信很简单，arduino上安装蓝牙模块，我用的是HC-06，你也可以试试其他的，然后手机端安一个蓝牙串口APP，比如SPP，直接可以用SPP编辑按钮和字符发送给arduino，简单方便
