对wx.getBluetoothDevices(OBJECT)获得的advertisData进行操作，相同的代码，IOS获取到的advertisData下有5个字节，是所需要的广播内容，但Android获取到的advertisData下只有三个字节，相对于IOS少了前面两个字节的内容。想问下这是我自己获取方式不对吗？还是目前小程序对应Android有部分功能不支持？
//获取所有已发现的蓝牙设备 getBluetoothDevices:function(){ var that = this; wx.getBluetoothDevices({ success: function(res){ // success var devices = res['devices']; var newDeviceItems = []; var device = []; for(var i=0;i<devices.length;i++) { device = devices[i]; if(device["name"] != "未知设备"){ var arryBuffer = new ArrayBuffer(); arryBuffer = device["advertisData"]; var uint8Array = Array.prototype.map.call(new Uint8Array(arryBuffer), x => ('00' + x.toString(16)).slice(-2)).join(''); var dataView = new DataView(arryBuffer); console.log(device["deviceId"]); var len = dataView.byteLength; console.log("len: "+len); console.log(uint8Array); var flag = true; for(var j=0;j<newDeviceItems.length;j++){ if(newDeviceItems[j].deviceId == device["deviceId"]){ flag = false; break; } } if(flag){ newDeviceItems.push({deviceName:device["name"],deviceId:device["deviceId"]}); } } } that.setData({ deviceItems: newDeviceItems }) }, fail: function(res) { // fail console.log("getBluetoothDevices-fail"); console.log(res); }, complete: function(res) { // complete console.log("getBluetoothDevices-complete"); console.log(res); } });} |
我不知道是不是他们微信开发人员的接口的更新，我现在调用接口的时候，在ios上获取的advertiseData数据长度比Android少，
