I ordered the EFCom Pro GSM module this month and to be honest it was beyond “fun” to get it working. Being cheap I ordered it for half of what. Power Supply: +5V; 1x GPRS Module -EFCom Pro; 1x 4 Frequency antenna; 4x Copper cylinder; Control via AT commands (GSM , and EFCOM.

Newer Post Older Evcom Home. Now that you have gotten a taste of how efco, AT Commands work, you can try out some more of them before moving on to developing sketches for Arduino to wfcom the GPRS. If while developing an Arduino sketch, you find that the GPRS isn’t what you expected it to do, then you will need to check your AT Commands and their sequence. Or you can write them on Projects page. It has been tested on Arduino Duemilanove but will work on any compatible variant.
So you received your GPRSwhat would be the first thing you would want to do with it? Hope the above helps someone not pull out as many hairs as I have Navigation Main page Product Tutorial Random page. A C program to perfom the same task as the serial relay sketch present above has also been developed and attached: Please write down what you have to say, your answers will help us improve our.
You can get the message center number by calling up the customer care center of the GSM Service Provider and asking them for it. Arduino One boards are confirmed to work as well January Another issue I encountered was the power requirement for the GSM module, many websites including the efcomm one claims a need for a 2A supply testing I couldn’t get it to consume more than 0.
But the library used. Retrieved from ” https: Extract the folder NewSoftSerial from within this. The amount of time the module takes to register on the network does vary, on Cell C in South Africa it took around 8 seconds before I could start sending messages.
Arduino software serial has wfcom limit of in baud rate due to the processing that would be required for faster baud rates.

The best way to do this using an Arduino board is described below. Click here to buy: The library can be obtained from here. This module support software power on and reset. On a Mac you may use the command line application “screen” available through Terminal.
Send sfcom a text SMS to your cell phone? Being cheap I ordered it for half of what the official Arduino GSM modules goes for so was determined to get it to work even though the documentation available at present pretty much doesn’t exist. However, efco must be aware that the buffer reserved for incoming messages are hardcoded to 64 bytes in the library header, efocm.
The program was developed on a Windows PC. XLoader is such a program which runs on Windows can upload. You may be getting funky characters, a favourite seems to be y To start off let’s try sending an SMS. The Additional Idea is the place to write your project ideas about this product, or other usages you’ve found. Please follow the following steps for running this sketch.
If, in spite of following the steps as specified above, you aren’t able to efcon the message on the target handset, then it might be that you need to set the SMS Message Center number. Sending an SMS however took about seconds, so I have a delay ofideally I should have a loop checking for serial available but it wasn’t such a complex project that required the additional code. This means that if the GPRS module responds pdo more data than that, you pri likely to loose it with a buffer overflow!
You can go through the AT Commands reference manual efocm figure out the sequence of commands required to do a particular task. Make sure to restart the Arduino IDE after the library. Now that our test setup is ready, let’s play around with some AT Commands before moving on to programming the Arduino to do it by itself instead of doing it manually.
Bug Tracker is the place you can publish any bugs you think you might have found during use. For users with Arduino 1. You just need connect as below: To do this, reload the serial relay sketch attached above in the getting started section into ATmegaP and type out the AT Commands manually and check the output.

This section is a work in progress Here are the list of connectors and pin headers present on-board the GPRS:. Navigation menu Personal tools Log in.
I followed the advice nonetheless and powered both the Efco and GSM module from a 5V 3A supply the smallest I had in the cupboard above 2A – just remember that the serial comms rely on having a common ground so if you power the Arduino from USB and the GSM module from a supply the serial seems to be a complete failure. See example code below. Posted by Etienne le Roux at If you want to make voice calls, you would also require a headset with microphone.
The Arduino sketch for sending an SMS is presented below. This page was last edited on 8 Mayat For developing efvom a program, we require installation of a new Arduino library – NewSoftSerial Notice: I connected two switches, the aim was to send an SMS when either switch was triggered and a voice call with if the first switch was triggered.
