DF-Bluetooth V3蓝牙模块上有一个两位拨码开关,如图12所示,1号开关LED Off是LINK灯的开关,可以关闭LINK省电,拨到ON为开,拨到1端为关;2号开关AT Mode是AT命令模式开关,拨到ON进入AT命令模式,拨到2端退出AT命令模式。应该使用AT指令给模块进行主从机模式或者其他参数设置,这时,AT命令模式开关和LINK灯的开关都要...
BluetoothData=BT_module.read(); //read it and save it Serial.println(BluetoothData); //print it on serial for testing purpose } 蓝牙收到的信息将基于我们将在下一步中安装的Android应用程序上按下的按钮。收到信息后,我们只需要触发相应的IR代码,如下所示 if (BluetoothData == '2') { irsend.se...
它保留了与 UNO 相同的强大外形和外设列表,并增加了板载低功耗蓝牙®(Bluetooth Low Energy,BLE,Nordic 的 nRF512822)功能和 6 轴加速度计/陀螺仪(Bosch 的 BMI160)。 Arduino 101 使用的 Curie™ 模块属于异构双核,包含两个微型内核,一个 x86 (Quark SE,SE 即 Second Edition) 和一个 32 位ARC 架构...
In the previous course, we learned to control the LED and other actuators using mobile phone Bluetooth. In this section, we will use phone’s Bluetooth to control the rotation of the servo to make an access control. Task Navigation
