I should write, suddenly my eyes caught the GSM modem kept on the corner of my desk. So I decided to write about it. I had the opportunity to work on GSM modem at the time of my major https://abishaisingh.wordpress.com/2012/06/03/gsm-modem-sim-300-sending-text-sms-arduino/comment-page-2/ project in my engineering. My project was “Vehicle Crash Monitoring System”. The motive was to create http://www.8051projects.net/t18431-p40/embedded-gsm-development/sim300cz-atmega16l.htm a device which will automatically detect the accident and call for help at the emergency no..  It is a new idea & I had to work hard on it. I had to use GSM modem for sending text sms on emergency number. Thus it call for help when it detects the accident of the vehicle. For my project, I used SIM 300. This cms error is tri-band, slim and compact so that it could be used in compact devices. I brought it for Rs.1600 (or 28.8$ approx) from a local shop. Now about the hardware, it consists of a DB9 port for communicating with the computer or with the micro-controller, a jack for power, a integrated module, a connector and a micro strip antenna , an interface circuit of Max 232. I am also posting the picture of my modem which is shown below. So, cme error 769 to work with the modem you have to make an interfacing circuit on Max 232, which will convert the ttl logic level from the micro-controller to RS 232 level, which is 9 or 12 volts. But making that circuit was a tedious task for me, so I used another trick. I found out the tx and rx pins of ttl level in Max 232 in the modem & soldered 2 wires from it. Also a 3rd wire  from the ground of the circuit. Then I connected those wires with the respective pins of my micro-controller & here I was ready to use my modem. First thing to know before working on any GSM modem is to get familiarized with the “at commands”. Embedded cellular modules(GSM Modems) are mainly controlled by the use of AT commands.  AT or Attention Commands are derived from the Hayes Command set (or AT command set) from 1977 to control the 300-baud Hayes Smartmodem. They are a set of command-language or instructions that are sent to a cellular module to perform different actions. Without AT commands one could not work with the modems. Here I will show you how to program your micro-controller for sending text message. The essential commands which will be used are: AT+CMGF=1 // this command will instruct SIM300 module to enter text mode. After giving command you should press enter key or send it ascii 0x0D character. AT+C

I am just new and trying to make it functional. RegardsShan ajay_bhargav Site Owner Thu Apr 30 2009, 09:16 AM #43 did you see the hardware specification of SIM300cz? if not then you must check it.if you dont have it then download it from www.sim.com luizsalomon [ Fresher ] Sat Jan 02 2010, 02:03 PM #44 Hello there!!!I'm developing an application using Atmel and the sim340 module.The GSM chip that I use is a 850MHz, so I have to change the module´s band using the command AT+CBAND="850....etc"It works fine, until I get a random error: error 769 - unable to get control of required module.This error occurs, like I said, randomly. I have only TXD, RXD and GND connected to the microcontroller. RTS and DTR are grounded. CTS, DCD and RI are floating. Communicating direct to the ATMEL thru TTL level.The problem is this random occuring error. If I use a 1800MHz chip, which I do not have to change band, everything works perfectly fine. All other AT commands respond perfectly. Using autobaud, at 9600.Any ideas???Thanx. ajay_bhargav Site Owner Mon Jan 04 2010, 12:02 PM #45 did you search for error in simcom document?is it coming in format "+CME ERROR: 769"?? if yes then check AT manual for SIM340 it must have
