Read data from GSM into a buffer. Parse the buffer and extract the actual message (sms) and then send it to another number.
you appear to send CTRL/Z serial(0x1a); before the Temperature, etc which would terminate the message do you received the "hello" part of the message
i am using atmel AT89S52 ,sim300 gsm modem . i just want to send a sms from the GSM modem without using is my code- #include void serialcomm() { TMOD=0x20; // Mode=2 TH1=0xfd; // 9600 baud SCON=0x50; // Serial mode=1 ,8-Bit data,1 Stop bit ,1 Start bit , Receiving on TR1=1; //
I am working on sim300, trying to receive sms on atmega16 via serial communication. When i send " *23# " sms to gsm modem from my mobile, gsm sends " \r\n+CMGR:\s"REC\sUNREAD","+919762148043",,"14/03/13,23:04:32+22"\r\n*23#\r\n\r\nOK\r\n " as response on serial port. I am getting this data on (...)

Dear friends At first I am sorry for my english. I would like to send and recieve sms by AVR and sim300. Can i use USART serial commiunication between atmega16 and sim300 to send sms for a mobile phome? I am familiar with CODEVISION and ATmega 16 ucontroller. please help me. Thank (...)
initially send First check by sending AT transmit_data('A'); transmit_data('T'); transmit_data(13); In receiving part you change like below unsigned char buffer; unsigned char count; void receive_data() interrupt 4 // Function to recieve data serialy from RS232 into microcontroller { buffer=SBUF; /
Hello everyone, I can send AT+CMGR= command to the gsm module but can only get the response as: +CMGR: "REC READ","+919483486213",,"13/04/29,17:33:34+22" instead of: +CMGR: "REC READ","+919483486213",,"13/04/29,17:33:34+22" Kindly advise Depends on how you read your res

I am using sim300 GSM/GPRS Module. But i am not able to send sms from this dont know why. The commands i am typing from Hyperterminal is as follow:- AT+CMGF=1 OK AT+CMGW="9650126047" > Hello!! this is Arun Sharma > (here i Press Control and Z Button +CMGW: 1 OK AT+CMGL="ALL" +CMGL: 1,"STO UNSENT","96501260
connect your GSM module with the serial port and in the hyperterminal send AT commands to send sms if it is working without any problem.the problem may be with the microcontroller program add one push button with the controller (if push button pressed once then AT command must be sent) and change your program (connect RX line of GSM modem (...)
1) For sending data to the board that include GPS device, you could use serial port and RS232 protocol or i2c 2) One GSM module such as sim300 can take data and send to any phone by sms message or GPRS module can send to the web. 3) For transfer data between IR module and GPS you can use some way such as (...)
hi avinesh, i tried ur similar steps on hyperterminal i able to send message, but i tried same steps in controller programe, unable to send message, can u help me please thanks Post your code to find out the problem
You can use code of any AT support modem to sim900, it will work fine, when i ported my sim300 code to sim900 it was not sending sms when i added some delay between at commands to worked
Hello I am looking to develop a device which could send some information (RFID tag serial no read from RFID Module) to a central server having fixed IP address. For this, I could use a GPRS Module such as sim300 and very easily accomplish the task. But the module is really costly and has a lot of extra features (call,sms,etc) than I use. (...)
hi, i have bought this sim300 mms module which comes with mms command set. i am using vodafone network in UK, i can send sms through the module but when i try to send MMS sometimes it fails and few times it sends OK reply but i never recieve it, i am not sure whats going on. vodafone settings: (...)
Hi all m using gsm modem of sim300 i have get the reponse of modem to AT command AT in a buffer and send this in a sms using AT+CMGS command. the problem m facing is something non-trivial m able to get the reponse of GSM modem into a buffer only after giving AT+CMGS. By this m getting two sms's one without data one with (...)
Hi everyone I need a precise temperature controller with PIC and send the reading through sms using a USB dongle. I prefered Huawei Technology E153U. Thanks You need to do part by part. First learn read temperature first using ADC. Then next year, you learn UART. Next 2 years, you learn USB Host.

I have a sim300 GSM/GPRS module which is connected to 8051. I have programs to send sms and to send data to remote server via GPRS. Both of these work fine separately. The Problem: If i send data to server through GPRS first, close connection and then send sms ,both (...)
hello friends, for MAFAIROZ: You are sending sms from PC with the end of CTRL+Z which is working but when you work with the microcontroller you need to send extra characters before CTRL+Z like this AT+CMGS=NUMBER Message CHR(10) .... LF CHR(13).... CR CHR(26).... CTRL+Z Hope it will work. ------------------------------- For (...)
First you have to learn basic interfacing with GSM/GPRS modem learn AT commands.. try to do simple interfacing with modem like dialing no, sending/recieving sms, checking signal strength etc. then you start GPRS related commands
