[图片]不知道在真机调试的过程中触发了什么别的误操作,这边PC端的控制台还没关掉,真机这边关掉了,然后想再次调试就出现了这个问题.,重启再来还是不行,有没有什么解决的办法和经验?

同样的代码，在安卓手机可以正常调用writeBLECharacteristicValue向蓝牙设备写入，但是在iphone手机（版本11.2.2）上调用，返回错误编码10008，错误信息“the value's length is invalid”，请大佬告知如何解决。代码如下： wx.notifyBLECharacteristicValueChange({      state: true,      deviceId: deviceId,      serviceId: notifyserviceId,      characteristicId: notifycharacteristicId,      success: function (res) {        console.log("notify success")        setTimeout(function () {          that.writeBLECharacteristicValue(deviceId, writeserviceId, writecharacteristicId)        }, 2000);      },      fail: function (res) {        console.log("notify fail:" + res.errMsg)      }, complete : function() {        wx.onBLECharacteristicValueChange(function (res) {          console.log(res)        });      }    })  },  writeBLECharacteristicValue: function (deviceId, writeserviceId, writecharacteristicId) {    var that = this    let buffer = new ArrayBuffer(1)    let dataView = new DataView(buffer)    dataView.setUint8(0, 0)    wx.writeBLECharacteristicValue({      deviceId: deviceId,      serviceId: writeserviceId,      characteristicId: writecharacteristicId,      value: buffer,      success: function (res) {        console.log('write success')      },      fail(res) {        console.log('write fail')        console.log(res)      }    })  },
