这样写读出来的数据会被覆盖掉，怎么解决，求助！ if (res.characteristics[i].properties.read) {                 console.log("readServicweId：", myUUID);                 console.log("readCharacteristicsId：", res.characteristics[i].uuid);                 that.setData({                     characteristics:[                         ...that.data.readCharacteristics,                         {                             readServicweId: myUUID,                             readCharacteristicsId: "CEB5555A-55E1-5555-55F5-EA0736155555",                         }                     ]                 })               }               if (res.characteristics[i].properties.write) {                 console.log("writeServicweId：", myUUID);                 console.log("writeCharacteristicsId：", res.characteristics[i].uuid);                 that.setData({                   writeServicweId: myUUID,                   //writeCharacteristicsId: res.characteristics[i].uuid,                   writeCharacteristicsId: "BEB5555A-55E1-5555-55F5-EA0736155555",//手动设置writeCharacteristicsId为这个UUID，为了方便写死在这里                 })               }

对接低功耗中心蓝牙设备，notifyBLECharacteristicValueChange成功，writeBLECharacteristicValue也是成功，但是无法接受设备返回数据，onBLECharacteristicValueChange  lanyatest10(event){       var that = this;       console.log("开始接收数据");       function ab2hex(buffer) {         let hexArr = Array.prototype.map.call(           new Uint8Array(buffer),           function(bit) {             return ('00' + bit.toString(16)).slice(-2)           }         )         return hexArr.join('');       }       wx.onBLECharacteristicValueChange(function (res) {         console.log("characteristicId：" + res.characteristicId)         console.log("serviceId:" + res.serviceId)         console.log("deviceId" + res.deviceId)         console.log("Length:" + res.value.byteLength)         console.log("hexvalue:" + ab2hex(res.value))         that.setData({           info: that.data.info + ab2hex(res.value)         })       })     },

小程序真机调试报错 SystemError (appServiceSDKScriptError) Cannot read property 'getGlobalWebviewIds' of undefined TypeError: Cannot read property 'getGlobalWebviewIds' of undefined

怎么使用UUID，连接设备
