dele-sunmi-btprinter

dele-sunmi-btprinter 是商米外置打印机的蓝牙操作插件

加载插件

    import { useBtprint } from '@/uni_modules/dele-sunmi-btprinter';
    import { OpenBluetoothAdapterOptions,GetBluetoothDevicesOptions,CommonOptions,StopBluetoothDevicesDiscoveryOptions,StartBluetoothDevicesDiscoveryOptions } from "@/uni_modules/dele-sunmi-btprinter/utssdk/interface";
    import { BluetoothManager } from "@/uni_modules/dele-sunmi-btprinter/";
    import { InitConfig } from '@/uni_modules/dele-sunmi-btprinter/utssdk/interface';

初始化

  const btPrint : BluetoothManager = useBtprint({
  /**
   * 是否请求地理位置权限，可选参数
   */
  needLocation: false,
  /**
   * 是否需要在后台访问位置信息，可选参数
   */
  accessBackgroundLocation: false
} as InitConfig);

var btDeviceId = "";
var btDeviceName = "";

初始化蓝牙

btPrint.openBluetoothAdapter({
  success: ((res) => {
    console.log("初始化蓝牙成功" + res.errMsg);
    console.log(JSON.stringify(res));
  }), fail: ((res) => {
    console.log("初始化蓝牙失败" + res.errMsg);
    console.log(JSON.stringify(res));
  }), complete: ((res) => {
    console.log("初始化蓝牙结束");
    console.log(JSON.stringify(res));
  })
} as OpenBluetoothAdapterOptions);

蓝牙扫描

btPrint.onBluetoothDeviceFound((res) => {
    console.log(res);
    console.log('开始监听寻找到新设备的事件');
    this.getBluetoothDevices();
});

btPrint. startBluetoothDevicesDiscovery({
    success: ((res) => {
        console.log('开始搜索蓝牙设备' + res.errMsg);
    }),
    fail: (e) => {
        console.log(e);
        console.log('搜索蓝牙设备失败，错误码' + e.errCode);
    }
} as StartBluetoothDevicesDiscoveryOptions); 

匹配蓝牙

var deviceId = btDeviceId;
console.log("conne id -->"+deviceId)
btPrint.createBond({
    deviceId,
    success: (res) => {
        console.log(res);
        console.log('匹配蓝牙返回:' + res.errMsg);
    },
    fail: (err) => {
    }
} as CommonOptions);

连接蓝牙

var deviceId = btDeviceId;
console.log("conne id -->"+deviceId)
btPrint.createConn({
    deviceId,
    success: (res) => {
        console.log(res);
        console.log('连接蓝牙返回:' + res.errMsg);
    },
    fail: (err) => {
      console.error("连接失败")
                     }
} as CommonOptions);

打印测试

btPrint.sendData("这里商米打印机测试1\n这里商米打印机测试2\n这里商米打印机测试3\n这里商米打印机测试4\n这里商米打印机测试5\n这里商米打印机测试6\n")

获取设备列表

      getBluetoothDevices:function(){
  btPrint.getBluetoothDevices({
    success: ((res) => {
      console.log(res.devices.length);
       res.devices.map((item) => {
        const {
          deviceId,
          name,
          localName,
          RSSI
        } = item;
        if(item.name.startsWith("CloudPrint")){
           console.error("匹配的蓝牙名称-->"+item.name)
           btDeviceName = item.name
           btDeviceId = item.deviceId
           //关闭搜索
           this.stopBluetoothDevicesDiscovery()
        }             
        // 其他业务逻辑
      });
    })
  } as GetBluetoothDevicesOptions); 
},

停止搜索蓝牙设备

stopBluetoothDevicesDiscovery:function(){
  console.log("stopBluetoothDevicesDiscovery funciton")
 btPrint.stopBluetoothDevicesDiscovery({
     success: ((res) => {
         console.log('停止搜索蓝牙设备' + res.errMsg);
     })
 } as StopBluetoothDevicesDiscoveryOptions);
