B4R Question Application that performs http POST with SIM900

[ThePuiu]

This is the first time when I try to write a B4R application! I have an application written for Arduino that has a malfunction and I would like to try a transcript of it. The application must make a POST call to a server using the Arduino UNO and SIM900A. The service on the server works fine. His call is like: http://mysite.com/post?imei=xxxx&v1=0&v2=0
I do not know if there is a dedicated library for working with AT commands or higher level.
Can you give me some advice on where to start?

Thank you!

I tried to run the program suggested by Erel after I modified the APN. I don't know why the application doesn't seem to run.
I say this because the message Log("AppStart") from AppStart does not appear in the Log window.
I used exactly the same connections as in the example and the MEGA 2560 as the development board. In attached file is the full content of Log window.
What is wrong?

Have you tried to reset the board after running the program?
