本人是初学者，想请教各位一个问题：如何用GPRS模块发送GPS的数据到yeelink上？
下面的代码是发送普通数值的。（发送普通数值和发送GPS定位的数据有什么区别！？{:soso_e154:} ）#include <stdio.h>
#include <math.h>
int i;
int len;
int times;
int temp;
int t;
char xinlv;
char post[]={//提交数据包
"POST /v1.0/device/12797/sensor/aaaaa/datapoints HTTP/1.1\r\n"
"Host: api.yeelink.net\r\n"
"Accept: */*\r\n"
"U-ApiKey:587407b0532721175514efd429f5dc98\r\n"
"Content-Length: dt\r\n"
"Content-Type: application/x-www-form-urlencoded\r\n"
"Connection: close\r\n"
"\r\n"
"{\"value\":xxxxxx}\r\n"
};//xx用来填充数值
char post_reserve[]={//提交数据包
"POST /v1.0/device/12797/sensor/aaaaa/datapoints HTTP/1.1\r\n"

"\r\n"
"{\"value\":xxxxxx}\r\n"
};//xx用来填充数值
char xinlv_sensor_id[]={"21121"};
