《ESP32 学习笔记》 之 ESP32 模拟 蓝牙鼠标-Mouse

1.简介

上一篇介绍了 ESP32模拟蓝牙键盘 的操作，那么如何让它模拟出一个鼠标呢~

2.硬件平台

安信可 NODEMCU-32S 开发板：

3.软件平台

Arduino (1.8.10)     或     VScode 环境下 PlatformIO 插件

4.库文件

4.1 ESP32_BLE_Arduino

ESP蓝牙驱动库，地址：https://github.com/nkolban/ESP32_BLE_Arduino

4.2 ESP32-BLE-Keyboard

ESP32鼠标模拟库，依赖于ESP32_BLE_Arduino这个库，地址：https://github.com/T-vK/ESP32-BLE-Mouse

5.示例程序

5.1 模拟鼠标按键测试

请注意：建议打开几个网页，在网页中测试！网页在前进/后退，右键菜单......

#include <BleMouse.h>

BleMouse bleMouse("ESP32蓝牙鼠标","Espressif",100);//其中“ESP32蓝牙键盘”为键盘名称；"Espressif"为制造商

void setup() {
  Serial.begin(115200);
  Serial.println("Starting BLE work!");
  bleMouse.begin();
}

void loop() {
  if(bleMouse.isConnected()) {
    Serial.println("左键点击");
    bleMouse.click(MOUSE_LEFT);
    delay(500);

    Serial.println("右键单击");
    bleMouse.click(MOUSE_RIGHT);
    delay(500);

    Serial.println("滚轮点击");
    bleMouse.click(MOUSE_MIDDLE);
    delay(500);

    Serial.println("后退按钮点击");
    bleMouse.click(MOUSE_BACK);
    delay(500);

    Serial.println("前进按钮点击");
    bleMouse.click(MOUSE_FORWARD);
    delay(500);

    Serial.println("同时单击鼠标左键和鼠标右键");
    bleMouse.click(MOUSE_LEFT | MOUSE_RIGHT);
    delay(500);

    Serial.println("同时单击鼠标左键+鼠标右键和滚轮");
    bleMouse.click(MOUSE_LEFT | MOUSE_RIGHT | MOUSE_MIDDLE);
    delay(500);

  }
}

5.2 模拟鼠标移动/滚轮滚动

测试代码时，请将鼠标光标放在你的代码上！你将会看到你的代码在上下翻滚，鼠标光标在画正方形。
