https://developers.weixin.qq.com/miniprogram/dev/api/device/bluetooth-ble/wx.notifyBLECharacteristicValueChange.html 安卓正常，IOS调用wx.notifyBLECharacteristicValueChange无回调，既没有调用成功方法，也没有调用失败方法、complete也没有被调用。 如果删除一个参数就会失败，提示参数异常。   console.log('111111111111111111111')     var  that = this     console.log("ddddd:",app.globalData.wendudeviceMac,app.BLEInformation.notifyServiceId,app.BLEInformation.notifyCharaterId)     wx.notifyBLECharacteristicValueChange({           // type: 'notification',           state: true,           deviceId: app.globalData.wendudeviceMac,           serviceId: app.BLEInformation.notifyServiceId,           characteristicId: app.BLEInformation.notifyCharaterId,//notifyCharaterId,           type:'notification',       success: function (res) {         console.log('222222222222222222')    },       fail:function(res){         console.log('333333333333333')         console.log("失败：",res)       },       complete:function(res){         console.log('44444444444444444444444')         console.log("最终：",res) 只输出  console.log('111111111111111111111')     var  that = this     console.log("ddddd:",app.globalData.wendudeviceMac,app.BLEInformation.notifyServiceId,app.BLEInformation.notifyCharaterId) 其他的都没有响应。
