I want send Meter_data and sensor data sever by HTTP using the GET Method

Hi, i am trying to send Meter_data and sensor data to Server at HTTP Level through GET Method, how we send dynamic data continuously ? every time voltage will be change here i am storing data in the buffer but how i need to send server please suggest me .my server understand only GET Method.

have a great day…

Hi,
You can see this example for Telit modules. I used a PHP code to get data. You can try the same for SIMCOM module request.
