说明：  EC20模块AT指令驱动,EC20是移远一款带有GPS功能的LTE模块，代码实现了AT指令数据收发 1、使用 AT+QGPSCFG 对GPS参数进行配置，此步骤不进行亦可使用（采用默认参数）。 2、使用 AT+QGPS 开启GPS功能，激活NMEA端口开始上报GPS NMEA数据，也可通过AT指令端口获取NMEA GPS数据(EC20 module is driven by at command. EC20 is a LTE module with GPS function. The code realizes at command data receiving and transmitting 1. Use at + qgpscfg to configure GPS parameters. This step can be used without (using default parameters). 2. Use at + qgps to turn on GPS function, activate NMEA port to start reporting GPS NMEA data, or obtain NMEA GPS data through at command port)
