如题，调用企业微信JSSDK ibeacon接口方法startBeaconDiscovery一直报11001 错误 bt service unavailable， 我开了蓝牙调用怎么会报这样错误

                        wx.ready(function(){
                            var uuid = ['e2c56db5-dffb-48d2-b060-d0f5a71096e1']
                            wx.startBeaconDiscovery({
                                uuid:uuid,
                                success(res) {
                                  console.log(res)
                                }
                            })
                        })
