Receive calls and SMS
We follow the series of tutorials dedicated to the GPRS modules, and how could it be otherwise, this time we have to receive SMS and calls. Also we will identify the number that is calling us or sending the SMS and we will read its content using the serial monitor. If you have followed the previous session you will see that it has no difficulty
In the following sessions we will use the module to notify us when certain situations occur and to perform the actions that we order wherever we are. Of course, we will have to make sure that he only answers before us, lest someone make a mistake and send our project to the bitter end.
Here we leave the link to the new session:
We hope you enjoy it. Greetings from Prometec.
