你好，iOS上是正常的吗

//第一阶段 
			// 1.确定蓝牙状态
			openBluetooth: function() {
				var that = this
				wx.openBluetoothAdapter({
					success: function(res) {
						that.getBluetoothAdapterState();
					},
					fail: function() {
						wx.showModal({
							title: '提示',
							content: '请打开蓝牙和定位功能',
						})
					}
				})
			},
			//2.获取本机蓝牙适配器状态
			getBluetoothAdapterState: function() {
				let that = this
				wx.getBluetoothAdapterState({
					success: function(res) {
						if (res.available) { //蓝牙适配器是否可用
							that.startBluetoothDevicesDiscovery();
							if (res.discovering) { //是否正在搜索设备
								// wx.stopBluetoothDevicesDiscovery({
								// 	success: function(res) {
								// 		console.log(res)
								// 	}
								// })
							}
						} else {
							wx.showModal({
								title: '提示',
								content: '本机蓝牙不可用',
							})
						}
					},
				})
			},
			// 3.开始搜索蓝牙设备
			startBluetoothDevicesDiscovery: function() {
				var that = this
				wx.startBluetoothDevicesDiscovery({
					success: function(res) {
						that.getBluetoothDevices(res);
					},
					fail: function() {
						wx.showModal({
							title: '提示',
							content: '搜索周边设备失败:' + res,
						})
					}
				})
			},
			//4.获取在蓝牙模块生效期间所有已发现的蓝牙设备。包括已经和本机处于连接状态的设备。
			getBluetoothDevices: function(res) {
				let that = this
				wx.getBluetoothDevices({
					success: function(res) {
						let devices = JSON.stringify(res.devices);
						that.devicesLists = res.devices.filter(item => item.name != '未知设备');
						if (devices.length > 0) {
							// 在蓝牙模块使用流程结束后及时调用 wx.closeBluetoothAdapter 释放资源
							// wx.stopBluetoothDevicesDiscovery({

							// })
						}
					},
					fail: function() {
						wx.showModal({
							title: '提示',
							content: '获取蓝牙设备失败:' + res,
						})
					}
				})
			},
//第二阶段
			//1.连接用户点击选中的设备
			createBLEConnection(deviceId) { //连接选中的设备
				var that = this
				that.deviceId = deviceId
				wx.createBLEConnection({
					// 这里的 deviceId 需要已经通过 createBLEConnection 与对应设备建立链接

					},
					fail() {
						wx.showModal({

			//2.获取设备服务信息
			getBLEDeviceServices: function() {
				var that = this
				wx.getBLEDeviceServices({
					deviceId: that.deviceId,
					success: function(res) {
						/* 获取连接设备的所有特征值 */
						for (let i = 0; i < res.services.length; i++) {

					fail: function() {

			//3.获取设备特征
			getDeviceCharacteristics(services) {

					deviceId: that.deviceId,
					serviceId: services.uuid,
					success: function(res) {

								that.characteristicId = item.uuid
								that.serviceId = services.uuid


								var str =
									'<div style="padding:10% 20px"><h4 style="text-align:center;">尊敬的会员您好，</h4></div>';
								that.writeBLECharacteristicValue('1')
								console.log('获取到具有写功能的特征了', item)
								return
							}
						}


					}
				})
			},
			//4.往蓝牙写数据
			writeBLECharacteristicValue(str) {
				let that = this
				let dataBuffer = new ArrayBuffer(str.length)
				let dataView = new DataView(dataBuffer)
				for (var i = 0; i < str.length; i++) {

				}
				// console.log('dataBuffer', dataBuffer)
				// console.log('deviceId', that.deviceId)

					value: dataBuffer,
					success: function(res) {
						console.log('写入成功', res)
						wx.closeBLEConnection({
							deviceId: that.deviceId,
							success(res) {
								console.log('关闭连接这个设备', res)
							}
						})


					},
					fail: function(res) {
						wx.showModal({
							title: '提示',
							content: '写入失败',
						})
					}
				})
