wx.onBluetoothDeviceFound查询不到 低功耗 设备？
我们这边是让同事开发了一个可以用蓝牙连接的硬件设备， 硬件蓝牙设备的版本是： 蓝牙 V4.2 BR/EDR， 低功耗蓝牙 然后我这边使用的是官方文档蓝牙扫描相关的API，但是没有扫描到设备，所以问一下怎么回事 async initBT() { let allList = []; this.btLoading = true //开启蓝牙模块 console.log('openBlue'); await wx.openBluetoothAdapter({ fail:(err=>{ console.log('openBlue',err); wx.showToast({ icon:'error', title:'请开启蓝牙', }) }) }) console.log('bluetoothAdapterState',bluetoothAdapterState); console.log('startScan'); await wx.startBluetoothDevicesDiscovery({ fail:(err=>{ console.log('startScan',err); wx.showToast({ icon:'error', title:'扫描蓝牙失败', }) }) }) //获取蓝牙适配器状态 let bluetoothAdapterState = await wx.getBluetoothAdapterState() console.log('bluetoothAdapterState',bluetoothAdapterState); // 不在搜索中 if (bluetoothAdapterState['discovering']) { console.log('scanning'); wx.onBluetoothDeviceFound(res => { allList = [res.devices,...allList]; allList.forEach(resItem=>{ resItem.forEach(item=>{ if(item.connectable){ const device = item; const name = device.name || '' const localName = device.localName || '' const deviceId = device.deviceId const mac = wx.ab2hex(device.advertisData) if (this.deviceList.findIndex(e => e.deviceId === deviceId) === -1) { this.deviceList.push({ mac: mac, name: name, localName: localName, deviceId: deviceId, advertisData: this.ab2hex(device.advertisData).substring(0, 16) }) } } }) }) }) } setTimeout(async ()=>{ console.log('deviceList',this.deviceList); wx.getBluetoothDevices({ success:(res)=>{ console.log('allRes',res) res.devices.forEach(item=>{ if(item.connectable){ console.log('item',item) } }) } }); await wx.stopBluetoothDevicesDiscovery() this.btLoading = false },5000) },
