wx.startBeaconDiscovery 是循环调用 ?还是只调用一次
例如 : setInterval( function(){
wx.startBeaconDiscovery ()
wx.getBeacon() or wx.onBeaconUpdate()
wx.stopBeaconDiscovery()
} ,1000)
还是 wx.startBeaconDiscovery ();
setInterval( function(){ wx.getBeacon() } ,1000)
or wx.onBeaconUpdate();
longtime… wx.stopBeaconDiscovery();
