连接上后，扫描到服务，再开启通过，这里应该不可能空

就是开始那个读的服务时报错了，我一层一层去打点调试出来的，改了之后，才能正常读取外围设备发的数据。

每次都是newBleConnector characteristic每次都会赋值。
我这边状况是，write和notify是2个不同characteristic。
有时正常，读写发送都好着。
有时候，写入一次，然后接收到返回，之后再发送都是发送回调成功，实际下位机没接收到。需要重新启动APP。

非常感谢 @wangjinchan 的讨论，通过源码和Debug发现，很可能是下位机对于一条指令的结束没有给出正确的反应，比较合理的尝试是修改MTU的大小，当然下位机是需要能支持的。
