This is a module equipped with Bluetooth functionality.
配备蓝牙功能的模块。


It uses Bluetooth 2.0, which may present issues when used with iOS (Apple products).
使用蓝牙2.0，可能与iOS（苹果产品）存在兼容性问题。


Testing with an iPhone 13, it was found that while messages from the iPhone to the HC-06 were displayed on the Serial Monitor, the reverse was not true, indicating an issue with operation in that direction.
在iPhone 13测试中，iPhone向HC-06发送的消息可显示在串行监视器，但反向通信无法正常工作。


There are models that can switch between Master and Slave roles and models that are fixed as Slave. Note that the Slave fixed models cannot change between master and slave roles using AT commands.
存在主/从切换型号和从机固定型号。从机固定型号无法通过AT命令切换角色。

=== Operation Check ===
After uploading the code, enter AT in the Serial Monitor to test the operation.


If OK is displayed, it indicates that the module is functioning correctly.
=== 操作确认 ===
上传代码后，在串行监视器输入「AT」
显示「OK」即为正常

    Serial.println("Serial start");
}

void loop()
{
    // 蓝牙串口数据转发至串行监视器
    if (BTSerial.available())
    {
        Serial.write(BTSerial.read());
    }

    // 串行监视器输入转发至蓝牙串口  
    if (Serial.available())
    {
        BTSerial.write(Serial.read());
    }
}


操作确认

上传代码后，在串行监视器输入「AT」 显示「OK」即为正常
