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？

樱满集

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
    "OST /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
    "OST /v1.0/device/12797/sensor/aaaaa/datapoints HTTP/1.1\r\n"
