摘要：小程序蓝牙模块现在是都搜索不到设备了
展开：//index.js//获取应用实例constappgetApp()Page({data:{},onLoad:function(){wx.openBluetoothAdapter({success:function(res){console.info(res);},fail:function(res){console.info(res);wx.showModal({title:提示,content:监测到系统未开启蓝牙，请前往设置开启蓝牙模块！,})}})wx.onBluetoothAdapterStateChange(function(res){console.log(`adapterStatechanged,nowis`,res)if(res.available){wx.showToast({title:蓝牙已开启});}else{wx.showToast({title:蓝牙已关闭});}})wx.startBluetoothDevicesDiscovery({success:function(res){console.log(res)}})setTimeout(function(res){wx.getBluetoothDevices({success:function(res){console.log(res)}})},10000);wx.onBluetoothDeviceFound(function(devices){console.log(newdevicelisthasfounded)console.dir(devices);wx.getBluetoothDevices({success:function(res){console.log(res)}})})},getBluetoothDevices:function(){letthatthis;wx.getBluetoothDevices({success:function(res4){console.log(res4);for(letitemofres4.devices){console.log(item.name.trim())console.log(item.name.trim().length)}}})},startsearch:function(){wx.startBluetoothDevicesDiscovery({success:function(res){console.log(res)}})},})我这样写得到的array永远为0，用了多个真机调试都没用，是不是蓝牙模块有问题
