GPRS协议与AT命令流程说明 - (第二十六讲)

视频讲解如下：

工程源码下载：GPS定位系统系列教程源码下载

官方教程：https://docs.ai-thinker.com/gprs/examples

GPRS所有流程命令如下，共10条命令：

AT+CCID  查询SIM
AT+CREG?  查询网络状态
AT+CSQ  查询信号强度
AT+CGATT=1  附着网络
AT+CGDCONT=1,"IP","CMNET"  设置PDP参数
AT+CGACT=1,1  激活PDP
AT+CIPSTART="TCP","{Server_Ip}",{Server_Port}  连接TCP服务器
AT+CIPHMODE=1  查询透传默认参数
AT+CIPTMODE=1  启动GPRS
+++  停止GPRS

串口的调试助手的执行效果，我这边就不演示了，直接按顺序发送指令即可。

下位机模拟器中已经集成了GPRS的命令集，可直接采用下位机模拟器进行测试：

操作流程如下：

1、先打开串口

2、设置好模拟器的公网IP和端口

3、按下A9G上的复位按钮，复位一下A9G，等待启动成功

4、点击“初始化GPRS”按钮

5、点击“启动GPRS”，此时就可以进行数据透传发送数据了。

6、点击“停止GPRS”可关闭输出。
