C program to send and receive data from beaglebone black to quectel C20 module via UART using AT commands

[CHITRA DILLI]

Hello all

i am using beaglebone black and quectel EC 20 module(mainly used to send data to web server) to send and receive data using AT commands via UART communication.

I need a C Code(only c code, not for linux based system). I use a example project for UART and in that example project will link the c code(the one with AT command) and see whether the data is sent an received using AT command.

first i will do with baeglebone black and pc using putty terminal and the second step would be using beaglebone and quectel module

I am new to C coding and AT commands.
so please do help with proper code

or [I HAVE ATTACHED THE MAIN EXAMPLE CODE, Please do go through and tell me how to add AT commands and view them in putty]
