Arduino - VII

After the last post on Arduino where we added the time element to Serial output, it is time to take a look at GSM (Global System for Mobile Communication)  Shield in conjunction with Arduino Uno. We will be using SIM800 for all the work in this post

There is minimal effort in setting up the circuit. The communication between Arduino and the GSM Shield will be the Rx, Tx and Ground on Arduino to Tx, Rx and Ground on GSM Shield, respectively, as is shown below:

Note that GSM Shield should have the SIM card. The code is shown below:

We can start the monitor on Arduino and pass the following commands:

AT 

AT+GMI

AT+GMM

A/

AT&V

The output is shown below:

AT is used to check if the GSM Shield is online.

AT+GMI returns manufacturer details

AT+GMM returns the model details

A/ returns results of last command

AT&V returns current configuration details

This concludes this brief post
