我是靠谱客的博主冷艳金针菇，最近开发中收集的这篇文章主要介绍EC20 TCP/IP指令例程，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

串口已经调试通过；EC20 TCP/IP指令例程具体指令如下

/* Use AT+CPIN?/AT+CREG?/AT+CGREG? to query the SIM status and network registration status */
[2015-09-14 13:56:10:185_S:] AT+CPIN?
[2015-09-14 13:56:10:208_R:] AT+CPIN?

[2015-09-14 13:56:10:208_R:] +CPIN: READY

[2015-09-14 13:56:10:208_R:] OK
[2015-09-14 13:56:10:210_S:] AT+CREG?
[2015-09-14 13:56:10:223_R:] AT+CREG?

[2015-09-14 13:56:10:223_R:] +CREG: 0,1

[2015-09-14 13:56:10:223_R:] OK
[2015-09-14 13:56:10:226_S:] AT+CGREG?
[2015-09-14 13:56:10:239_R:] AT+CGREG?

[2015-09-14 13:56:10:239_R:] +CGREG: 0,1

[2015-09-14 13:56:10:239_R:] OK

第一步：配置 context profile

AT+QICSGP=1,1,”UNINET”,””,””,1 //配置 context profile 1，这里以中国联通举例 AT+QICSGP=1,1,"CMNET","","",1

//移动APN：CMNET；联通APN：UNINET OK

设置GPRS连接模式，设置命令AT+QICSGP=1,"CMNET"中国移动或者中国联通卡，通过GPRS连接TCP的这条命令可以省略，但是不建议省略。

/* Use AT+QICSGP=1,1,"UNINET","","",0 to set APN as "UNINET",user name as "",password as ""*/
[2015-09-14 13:56:10:243_S:] AT+QICSGP=1,1,"UNINET","","",0
[2015-09-14 13:56:10:255_R:] AT+QICSGP=1,1,"UNINET","","",0
[2015-09-14 13:56:10:271_R:] OK

第二步：激活 context profile
/* Activate context profile */
[2015-09-14 13:56:10:274_S:] AT+QIACT=1
[2015-09-14 13:56:10:287_R:] AT+QIACT=1

[2015-09-14 13:56:11:167_R:] OK

/* Query the status of the context profile */
[2015-09-14 13:56:11:181_S:] AT+QIACT?
[2015-09-14 13:56:11:199_R:] AT+QIACT?

[2015-09-14 13:56:11:199_R:] +QIACT: 1,1,1,"10.23.163.28"

[2015-09-14 13:56:11:199_R:] OK

/* Use ATV1 to set the response format */
[2015-09-14 13:56:12:452_S:] ATV1
[2015-09-14 13:56:12:462_R:] ATV1

[2015-09-14 13:56:12:478_R:] OK

[2015-09-14 13:56:13:314_R:] DSR:1 CTS:1 (RI:1) DCD:0

[2015-09-14 13:56:13:328_R:] +QIOPEN: 0,0

[2015-09-14 13:56:13:434_R:] DSR:1 CTS:1 (RI:0) DCD:0

/* Use AT+QISEND=0 to send data to server, ">" from the UART or USB port indicates the following input data is considered as data to be sent. After receiving ">", input data (TEST), the maximum length of the data is 1460, the data beyond 1460 will be omitted. Then use <CTRL+Z> to send data. When receive SEND OK means the data has been sent */

AT+CFUN=1,1 //重启模块

AT+QSIMDET=1,1或AT+QSIMDET=1,0开启可以设置高电平或者低电平有效//SIM卡热拔插，同一个电路肯定不可以设置两种sim卡检测状态要么高电平有效要么低电平有效

AT+QSIMDET=0 关闭热拔插功能

通过AT命令开启SIM卡检查功能

举例：

AT+QSIMSTAT=1 //开启SIM卡热拔插状态报告

AT+QSIMDET=1,1或AT+QSIMDET=1,0//开启 SIM卡检测功能

当SIM卡拔出或者插上的时候，模块会有相应的提示：

+CPIN:NOT READY

AT+QSIMSTAT=1,1或AT+QSIMSTAT=1,0

Call Ready
