EC20模块GPS功能的AT指令顺序

可选：
AT+QGPSCFG=“gpsnmeatype”,2
只输出RMC信息
AT+QGPSCFG: “autogps”,1
上电即输出GPS信息，0为关闭
1.AT串口（波特率9600）输入“AT+QGPS=1”，启动GPS获取。（室外，大概一分钟）
NMEA串口（波特率9600）拿到的数据：（1次/s）

$GPRMC,060819.00,A,3129.190413,N,12018.869029,E,0.0,298.2,290421,4.8,W,A*21

$GPGSA,A,2,01,03,07,08,14,17,19,21,22,28,30,1.0,0.6,0.7*3F

2.AT串口（波特率9600）输入“AT+QGPSLOC=2”，获取坐标信息。
AT串口（波特率9600）拿到的数据：（1次/s）

+QGPSLOC: 060816.0,31.48651,120.31448,0.6,27.0,2,298.13,0.0,0.0,290421,11

3.关闭
