- 当前问题的表现

已搜索到蓝牙设备的mac地址，通过wx.createBLEConnection连接该设备，要么连接失败，或者连接成功后但无法写特征值。

调试信息如下：

使用IOS测试无任何问题，使用低版本的Android6.0手机也没有问题。

请参考具体的建立连接代码片段如下：

wx.createBLEConnection({

deviceId: deviceId,

// mainThread: false,

// needDiscoryService: true,

success: function (res) {

// wx.hideToast();

console.log('连接成功', res)

if (that.data.ios){

//从连接中获取serviceUUid与characterUUid 苹果机限制必须先获取才能使用

getDeviceService.call(that);

}

else {

that.setData({ tip: `当前连接设备: ${deviceName}`, isConnected: true, isModal: false, selectDevice: '' })

wx.showToast({

title: '连接成功',

})

that.closeModal();

that.selfData.connecting = false

}

不知是我代码调用有问题，还是手机有何设置未开启

请遇到类似问题的朋友方便的话帮忙答复一下，谢谢！
