Introduction
This post will be shown how to communicate the GPRS shield of Sixfab with Raspberry Pi 3 B+.Â
The Sixfab GSM/GPRS Shield allows the Raspberry Pi to connect to Internet. This shield uses AT commands to receive orders and execute a function, for example, an AT command to test if AT system works correctly. So the aim is to send an AT command and receive an OK answer, "I'm ready".Â
