如何看待微信公开课小程序热门讨论「小程序服务号蓝牙扫描后onScanWXDeviceResult不回调」
摘要：小程序服务号蓝牙扫描后onScanWXDeviceResult不回调
展开：wx.invoke(startScanWXDevice,{connType:blue,btVersion:ble},function(res){alert(JSON.stringify(res));});这里提示成功了。wx.ready(function(){//初始化设备库函数wx.invoke(openWXDeviceLib,{brandUserName:gh_b4ed57a5e824,connType:blue},function(res){alert(openWXDeviceLib+JSON.stringify(res));//新增步骤先判断是否有已经绑定设备wx.invoke(getWXDeviceInfos,{connType:blue},function(res){alert(getWXDeviceInfos+JSON.stringify(res));});});console.log(ononScanWXDeviceResult);wx.on(onScanWXDeviceResult,function(res){alert(onScanWXDeviceResult+JSON.stringify(res));});//手机蓝牙状态改变事件console.log(ononWXDeviceBluetoothStateChange);wx.on(onWXDeviceBluetoothStateChange,function(res){alert(onWXDeviceBluetoothStateChange+JSON.stringify(res));});//设备绑定状态改变事件console.log(ononWXDeviceBindStateChange);wx.on(onWXDeviceBindStateChange,function(res){alert(onWXDeviceBindStateChange+JSON.stringify(res));});//接收到设备数据console.log(ononReceiveDataFromWXDevice);wx.on(onReceiveDataFromWXDevice,function(res){console.log(onReceiveDataFromWXDevice+JSON.stringify(res));alert(onReceiveDataFromWXDevice+JSON.stringify(res));});});但是‘onScanWXDeviceResult’不执行回调，不知道为什么。但是我可以监听到onWXDeviceBluetoothStateChange，就是我打开和关闭蓝牙，都会弹出来{state:on}，提示蓝牙打开了和关闭了。
