GSM Modules are frequently used in IoT projects since it has the ability to send and receive data remotely. Though the GSM modules cannot send a vast amount of data generated by sensors, it is ideal for applications where small reasonable amount of data to be sent.

To display the messages received and sent, one 16x2 LCD will be used with two Push Buttons which will initiate sending and receiving of text messages after pressing the relative button. There are already several GSM projects are available interfaced with different kind of microcontrollers. Some of the projects with GSM modules are given below:. The module is controlled by using AT commands. Some of the AT commands are given below which will be important in this tutorial and will be used frequently.

The complete setup will look lik below:.

The complete code and the working video can be found at the end of this tutorial. Start with including necessary libraries for peripherals used in this tutorial. Also define the pin configuration of LCD. Next, initialise LCD selecting the function lcd. Just print a message to debug that if LCD is giving Output and interfaced properly.

Define the Push button data direction as Input Mode and define the pin number used. There are two functions in the code one to send message and other one to receive message. Detailed explanation is given below.

This function is used to send SMS to a number. AT command is sent to GSM module indicating the message text mode and on which number the message needs to be sent. In this function, the messages are received and printed in the LCD display screen. After receiving the SMS, it contains a string available at the serial1 port which also have the other data in it such as the time, date etc. Hence the other information is omitted and the remaining information that is the received message is displayed in the 16x2 LCD display.

To send Text Message, simply press the Left Push button. The SMS will be sent to the mobile number entered in the code. In case of any doubts or suggestions, please feel free to comment. Recommended Posts.

Each library is written in a way where user must prepare additional coding to support arhitecture where it is used.

Below is a brief description of each library. Each library has its own documentation page and Github repository with examples. Please take a look at reading below and check if it fits your needs.

After first version in JanuaryI decided to rewrite entire library to be more user friendy for future upgrades and to allow easier parsing without unexpected problems as that was in first version. It features less RAM usability than first library version. Other specs are:. It features basic 4 statement parsing as well as user defined custom statements when required for other application usage. Library is totally independent of platform, can be used on PC easily.

It consist of one input function, processing function and output data structure. There is no communication dependance. Tags: at commands at parser esp gps gsm nmea NMEA nmea parser parser simcom.

Whilst the AT commands are easy to understand and use, writing reliable embedded code for interfacing using them can be challenging. The base library provides the following functionality:. Extensions to the library, available from www. Example programs are currently available for the following hardware setups:. The "unsolvable puzzle" problem has also been resolved. You have unsaved changes. If you choose to leave all changes will be discarded.

The library abstracts low level communications between the modem and SIM card. It relies on the Software Serial library for communication between the moden and Arduino. Typically, each individual command is part of a larger series necessary to execute a particular function.

The library can also receive information and return it to you when necessary. The library tries to be as compatible as possible with the current Ethernet library. While it is not possible to simply run Ethernet-compatible code on the GSM shield as-is, some minor, library specific, modifications will be necessary, like including the GSM and GPRS specific libraries and getting network configuration settings from your cellular network provider.

There are two groups of examples for the GSM shield. There are examples to illustrate the possibilities of the shield, like how to send SMS messages and connect to the internet. There is also set of example tools that you can use to debug the functionality of the library and the hardware at lower level. Receive Voice Call : Check the status of the modem while getting voice calls. Enables voice communication through the modem. A microphone and speaker need to be added for full use.

This class is responsible for including the files that are part of the library that involve TCP communication.

The Server class creates servers which can send data to and receive data from connected clients programs running on other computers or devices. The GSMModem class facilitates diagnostic communication with the modem. The GSMScanner class provides diagnostic information about the network and carrier. The GSMBand class provides information about the frequency band the modem connects to. There are also methods for setting the band. Corrections, suggestions, and new documentation should be posted to the Forum.

Code samples in the reference are released into the public domain. The GSM class takes care of commands to the radio modem. This handles the connectivity aspects of the shield and registers your system in the GSM infrastructure. NB : A number of network operators do not allow for incoming connections from the public internet, but will allow them from inside their own.

The current use-case is Smart Street Lighting so availability of power is not an issue, however we would like to extend it to other use-cases where conserving power might be needed.

Result of the lib: I failed on my first try and I made this library obsolete and it is now archived on Github. To answer your question. I did not find any good library for AT commands which would work in 'non-blocking' mode or if it uses 'blocking', to have at least option for context switch in OS. I gave you enough reasons why I stopped personal development here and I started a new version which:.

This is the opportunity to invite all interested developers to support this project. I appreciate the work you've done to bring up the current version of the library. It is exactly what I was looking for. I will be integrating this library with ContikiOS and will provide it as a submodule in your project once you approve of the quality.

Thanks again for your detailed answer and prompt response. Could youme help me on how should I go about integrating the library with Contiki-OS without multithreading only pt support? I can work on extending the mtarch.

I am very interested in your progress on this work. We too have a need for a Contiki port for a modem driver. I have been working on Contiki OS from last 6 months, according to my understanding you should use border router and integrate your cellular code to that. ST has border router example code using WiFi as border router gateway.The unparalleled range of STM32 microcontrollers, based on an industry-standard core, comes with a vast choice of tools and software to support project development, making this family of products ideal for both small projects and end-to-end platforms.

This video is about the STM32L5, our recently announced ultra-low power microcontroller bringing a new security dimension. The STM32L5 is now in full production and all its ecosystem is available including hardware kits, software tools, firmware and all documentations of course.

For further information, you can refer to AN and AN application notes. Thanks to the graphics acceleration, memory integration, advanced display interfaces and smart architecture of STM32 microcontrollers, you can now enrich your applications with a high-end user experience with a limited total cost of ownership.
