/*
正面向2个双色指示灯，分别为：左红、左蓝、右红、右绿  四个LED
因为是双色灯，因此需要注意同一位置的指示灯两种颜色叠加时会有混色效果。比如：
红色+蓝色=紫色
===============
左红：4G模块指示灯
	 常灭--模块未工作  
   常亮--模块未插SIM卡  
   均匀闪烁--模块找网中
   慢闪1次--正在打开SOCKET连接
	 慢闪2次--正在发登陆包
	 慢闪3次--正常工作

左蓝：GPS模块指示灯
		常灭		--模块未工作
		慢闪1次 --未定位
		常亮 		--已定位
右红：电源指示灯
		开机后5秒常亮

右绿：水表通讯指示灯
   每收到水表数据包并解析成功，闪烁一次
