MCBleKit

该微信小程序开源项目代码库用于管理微信小程序中的蓝牙功能。支持初始化蓝牙适配器、扫描和连接蓝牙设备、获取设备服务和特征、监听特征值变化、读写特征值以及断开连接等操作。通过设置不同的监听器，可灵活处理蓝牙连接状态变化、设备发现、服务和特征发现等事件，适用于需要与蓝牙设备进行数据交互的微信小程序开发场景。
This WeChat mini program open-source project code library is used to manage Bluetooth functionality in WeChat mini programs. Support initialization of Bluetooth adapters, scanning and connecting Bluetooth.

示例代码
Example code:

在引用蓝牙管理类的js内引入 mcblekit 的模块，并将该模块的导出内容赋值给变量 MCBleKit.
Introduce the mcblekit module into the JS that references the Bluetooth management class, and assign the exported content of this module to the variable MCBleKit.

const MCBleKit = require('mcblekit')

   var writeServiceId = '108A'//write property service identifier
   var writeCharacteristicsId = '909C'//write property Characteristic identifier
   var serviceId = null
   var characteristicsId = null

   var mcblekit = MCBleKit.getSampleInstance("YOUR_BLUETOOTH_NAME")
   mcblekit.onCharacteristicFound((serviceId, res) => {
 
       for (var i = 0; i < res.characteristics.length; i++) {
           if (res.characteristics[i].uuid.toUpperCase().indexOf(writeCharacteristicsId.toUpperCase()) >= 0) {
                characteristicsId = res.characteristics[i].uuid

                //找到写入特征，开始写入数据 Find the write Characteristic and start writing data
                //判断是否已连接 Determine if it is connected
                if (mcblekit.connected) {
                     //发送数据write data Value
                     let buffer = new ArrayBuffer(2);
                     let view = new DataView(buffer);
                     view.setUint8(0, 0x0A);
                     view.setUint8(1, 0x01);
                     mcblekit.writeValue(buffer, 'writeNoResponse', serviceId, characteristicsId)
                }
                break
           }
       }

       console.log(`发现服务 ${serviceId} 的特征:`, res.characteristics);
   });

   mcblekit.onServicesFound((services) => {

       for (var i = 0; i < services.length; i++) {
           if (services[i].uuid.toUpperCase().indexOf(writeServiceId.toUpperCase()) >= 0) {
                serviceId = services[i].uuid
                break
           }
           console.log(`发现服务 ${services[i].uuid}`);
       }
   });
   mcblekit.bluetoothDeviceFound(() => {
       console.log('bluetoothDeviceFound:' + mcblekit.devices[mcblekit.devices.length - 1].name);
   });
   mcblekit.onConnectedStatusChange((connected) => {
       console.log('onConnectedStatusChange:' + (connected ? "connected" : "disconnected"));
   });
