AT Commands in Project Based Learning

Abstract

AT commands are strings of data that can be sent to a communication module for the purpose of programming it. The paper presents several applications for programming different types of modems, all of them using AT commands. The types of modems considered in the paper are dial-up modems, GPRS modems, Bluetooth modems,s, and WLAN modems. The paper shows how some of the modules used in the Project Based Learning experiment were programmed using AT commands. The paper also presents the results of a test that queries the opinion of the students engaged in this centeractivity, showing the effectiveness of PBL and outlining the difficulties arisen during the project realization.
