![]() ![]() Send/receive SMS messages, managed by the GSM_SMS class.Voice call handling, managed by the GSMVoiceCall class.All of your GSM/GPRS programs will need to include an object of this class to handle the necessary low level communication. This handles the connectivity aspects of the shield and registers your system in the GSM infrastructure. The GSM class takes care of commands to the radio modem.The library can also receive information and return it to you when necessary.Īs the library enables multiple types of functionality, there are a number of different classes. Typically, each individual command is part of a larger series necessary to execute a particular function. ![]() It relies on the Software Serial library for communication between the modem and Arduino. The library abstracts low level communications between the modem and SIM card. The modem executes operations via a series of AT commands. The GSM shield has a modem that transfers data from a serial port to the GSM network. With the Arduino GSM Shield, this library enables an Arduino board to do most of the operations you can do with a GSM phone: place and receive voice calls, send and receive SMS, and connect to the internet over a GPRS network. The GSM Library is included with Arduino IDE 1.0.4 and later. For more information, you can view this repository on GitHub. It can be still be downloaded and used, but is read-only and cannot be contributed to. This library is archived and is no longer being maintained. ![]()
