I am curious if I must use AT commands for interfacing the ESP8266 with my microcontroller board. I am planning on using TM4C123G for my IoT setup. I would like to know if its possible to interface ESP without using AT commands and embed functions in the C code itself to do the job of AT commands. I have relevant document related to ESP8266 but I would like to know if there is any documentation which I must read for my specific problem.
Thank You
