Interfacing-GSM-Module-and-Arduino

by jojo @ circuitstoday.com:

In this article, we are going to see how to interface GSM Module to Arduino. There are different kinds of GSM modules available in market. We are using the most popular module SIM900 and Arduino Uno for this tutorial. Interfacing a GSM module to Arduino is pretty simple. You only need to make 3 connections between the module and arduino. So lets get to business!

Thanks to the enhanced functionality of the M95 FA module, this new version of the favorite GSM/GPRS module can be used for even more applications.

Quectel M95 communication module is already well-known among designers and we can say, that also very favorite. Its producer also knows this fact, that´s why Quectel decided to come to the market not with a new type, which might have other package, functionality,…. but a new version of M95, marked as M95FA. M95 FA maintains compatibility with the previous versions M95A (R1.0) and M95 EB, plus it naturally adds something new …Similarly like M95EB , even the „FA“ supports eCall and DSSS (Dual SIM single standby), but also supports digital audio, secure data transfer thanks to the SSL and other. M95 FA is based on the latest MTK chipset, ensuring long lifetime and availability. M95 gained various international certificates and meets all requirements in the GSM/GPRS bands.

To make the development easier, M95 FA is also available on the so called adaptor board – M95FA-TEA-03-STD,usable with the M10EVBKIT.
Detailed information can be found in the Quectel M95 flyer, Quectel 2014 catalogue and upon request we´ll send you complete detailed SW and HW documentation.

Arduino Tutorial: GSM/GPRS SHIELD (SIM900) SMS Send and Receive Tutorial on Arduino Uno

In this video we are going to see, how easy it is to send and receive SMS messages using the Arduino GSM/GPRS shield (with SIM900 chip) from Tinysine. The shield is capable of sending and receiving SMS messages as well as making and receiving phone calls. It can also connect to the Internet using the GPRS network. But we will take a look at this later on in another video.

In this video, we connect to the GSM network of COSMOTE in Greece and we send an SMS message to a cell phone. Then we reply to Arduino and read the message in the Serial Monitor in the computer.

Moreover, new UMTS/HSPA module Quectel UG95 is pin-compatible with GSM/GPRS module M95 thus offering extraordinarily simple way to migrate to 3G without a PCB redesign.

To have a possibility to choose a component on a given PCB place according to our wish is certainly advantageous. For example in audio equipment to use a simple operating amplifier (for less demanding applications) or in other case to use a pin-compatible high-end operating amplifier for more demanding applications (on the same PCB position). This compatibility is common in some fields, in other ones not that much …

In a segment of GSM/GPRS/UMTS modules is this compatibility a sort of an exception, so arrival of the new Quectel UG95 module on the market can be an interesting solution how to use the same design for smaller GSM/GPRS/EDGE connection (with the M95 module) and also for a substantially faster UMTS/HSPA connection with the UG95 module.

Do you use 2G module M95 and you wish for a higher transfer speed?

UG95 offer extraordinary possibility to design your device able to work with M95 or also with UG95 module. UG95 features more pins than M95 but their position is compatible, so at a PCB design it´s possible to place all pins on a PCB and their real use will depend on whether you´ll use M95 or UG95.In result it´s possible to assemble the same PCB with M95 or UG95 module according to given application requirements.

UG95 is based on a new Intel XMM6255 chipset. In general, UMTS/HSPA transfer offers not only a higher transfer speed of pictures and data but mainly higher reliability of connection even in hazard conditions. That can be very important for critical applications like telemetry, process control, security and similar. Because from a new module we usually expect enhanced functionality, even in this field the UG95 has what to offer, for example:

  • rich set of internet protocols – TCP/UDP/PPP/MMS*/SMTP*/FTP*/SSL* (*-in development)
  • standard industrial interfaces – USB 2.0/UART/I2C/PCM
  • high sensitivity and top-class audio algorithms, digital audio output (PCM)

New module is available in a form of the module itself – UG95EA-02-NCH-STD (suitable for a mass usage into a target appliance) and also in a form of a known „adapter board“ UG95-TE-A mainly intended for development using the UC20EVBKIT development kit.

Detailed information will provide you the UG95 presentation, UG95 specification and the document Quectel UG95&M95 compatible design.

What´s more, M66 is currently the smallest quad band GSM/GPRS moduloe in the world … AT the same time it withstands strong frosts, so it´s ready for a wide spectrum of applications.

New extraordinary attractive communication module Quectel M66 asks its place maybe even in your application.
Does it deserve it? Most probably yes. Besides two basic facts mentioned in the name and perex of this article, it offers a lot of “smallnesses” making the life of a developer easier, for example:

  • Quectel OpenCPU functionality
  • power consumption only 1.3 mA (DRX=9)
  • easily applicable LCC package suitable for small and also big production series
  • powerful internet protocols embedded
  • based on the newest 2G chipset ensuring a long lifetime (availability) of the module
  • GPRS multi slot class 12
  • 3x UART/ 1x RTC
  • DTMF, QuecLocator, QuecFOTA for a simple software update, eCall

What to add? For a real decision and usage in your device we bring you the M66 presentation and mainly a complete documentation M66 (30 MB). In this package can be found a detailed description, various application notes, description of AT commands as well as SW tools.
MM66 offers a stable platform to build a quality product, moreover for an attractive price. As usually, even M66 is also available on a so called adaptor board – M66TE-A nabling usage through a connector – without soldering and also usage in a universal development kit M10EVBKIT.

Within a frame of novelties in Quectel communication modules, there´s also available the second version of the M95 – module – M95 R2.0, marked as M95FA which is fully compatible with a previous version of M95 but it also has another features like digital audio, DSSS a SSL.
Another novelty is the GPS/Glonass module L76 offering an advanced functionality, excellent sensitivity and various services (AlwaysLocate, advanced AGPS, LOCUS, …).
Comprehensive comparison of current Quectel modules can be found in the Quectel v3.4 brochure.

New antenna 2J620P will provide you a high quality GSM and GPS signal at once, moreover with a very simple assembly.

Tracking of vehicles or goods is still more used what naturally results into a requirement for a suitable antenna. One of them can be the 2J620P. It offers a very simple and elegant solution, as in fact it is “2 in 1” – two antennas in one enclosure, each with a separate RG174 cable and SMA connector. Assembly is absolutely simple – by means of included double-sided foam pad. Also supplied is even a small towel filled by isopropanol for cleaning of a place of assembly as well as antenna itself.

2J620P has a 2.14 dBi gain for GSM and 26-28 dB for GPS. The GPS portion is equipped by an active amplifier, that´s why requires 2.7-5.5V/15-25 mA power supply. In many applications can be also advantageous a flat shape without any nibs.

Detailed description of the antenna can be found in the 2J620P datasheet.
