Hi, I am using 8051 microcontroller with interfacing sim 300 modem My First aim is read signal strength from modem and show to 16*2 display. My code is below, My problem - The received signal strength - Not show to the display #include #include sbit rs=P1^0; sbit rw=P1^1; sbit en=P1^2;
Hello Every one, Am try to send and Receive SMS from sim900 with the help of Arduino UNO, I have write a program for that but sim 900 performing all the function like receiving Message , Calling to Someone, Receving call but not sending SMS My program as follows: #include SoftwareSerial mySerial(7, 8); char
hi we are interfacing sim 300 with PIC18f. ,using ccs compiler if i m sending at commands from microcontroller to modem , it is working perfect. we monitor via hyperterminal. but if i m checking for 'OK' after each at command, it receives only for 1st at command. here is my code void main() { char c; int8 i; for(i=0;i<10;i
hello everyone.. i have some problem with my thinking that how can i receive data from my pc based application to my sim900 module that is interfacing with lpc2148 along tcp/ip protocol. shall any one tell me how it is possible ?? thanks
Hi, Can you please tell me how to use those files(RTL,sim) in EXAMPLE CODES. How to write Data From pc -> fpga ddr3 Ram (with reference to ) Regards, Devi
I have write a code for sending message form gsm300 using 8051. but it is not working. plz tell me where is the problem? in the program or in ckt? #include #include #include #include #include void delay(unsigned int i); void tx0(unsigned char); void SMSString(unsigned char*text)
HI there, any help would be appreciated.. I am trying to read from the AD0831 ADC through the SPI inteface in proteus lite sim . It seems that I have set the correct flags and every thing but the ADC doesnot communiccate with the micocontroller at all. This is my configuration: SCK is RC3 SDI is RC4 SS is RA5. I think the algorith
my objective is to read message sent by some mobile number on the sim connected to gsm module.. LCD connected to 8051 i did followed so many tutorials all of those are really confusing.. they just explain the setup and then skip to the code.. i just want a step by step explanation for programming for this objective
Hello... I am using simcom sim900A module i have connected usb to serial cable with PC to sim 900A module, when i am trying to interface sim900a directly with PC in hyper terminal but not getting reply. what to do ?
hello I want to send and receive sms through gsm modem. I am using avr 128. I am able to send messages but I am not getting how should I receive a message. To read a message I need to send AT+CMGR=1. This will read the first message. But to read that I need to read response of this command i.e. in turn I need to read UBR. Now the response of t
hi al, Im interfacing sim 900 GSM Modem to microcontroller and sent GPRS AT commands.Connection is ok.But Im not able to view the webpage content in hyper terminal. I gave the following data after sending AT commands. GET /index.html HTTP/1.1 \r\n Host: \r\n Connection: Keep-Alive" \r\n; Accep
can i connect p0.0 and p0.1 of mcb2140 to modem's Rx and Tx or should i use serial ports com 0 and com1 of mcb2140 and give its output to max232. gsm modem is of simcom and i find that it has an in built max232
what is the basic codes or AT commands for interfacing sim900 with PsoC Microcontroller?
Hi Dears I am working on a project which detect fault in Distributed antenna system for this purpose i am using sim 100 GSM Module and AVR microcontoller problem is how i interface sim 100 GSM Module with antenna to give signal strength of each antenna?
hii everyone.. i am doing project which uses GPS and GSM. so please help me with code for interfacing gps and gsm with atmega16 already i have worked with AT commands but i am failing in interfacing them with micro controller please help me......... thanks in advance...
Hi, I am making a project related to GSM module in which i just want to send message but the error i am facing is how i connect that modem to microcontroller and how i get the output of GSM module on LCD 1602. i.e. Firstly When i send AT command to the GSM modem how i get OK on my LCD . Waiting for the Best Reply. Thank you :)
hi geeks I m working currently on a SMS-driven LCD display I m using at89s52 microcontroller , jhd204a lcd display and sim 300 gsm module the concept of the project is to display the msg from the authorized user in the LCD display and if the msg is frounm the authorized user the LCD should display "msg from unknown" and should forward the
is sim 300 gsm module available in Proteus? which microcontroller is suitable for interfacing with sim 300? is there any other software available for simulation which support sim 300?
Dear Friends i am interfacing GSM Module sim 900 and GPS Module Holux M89 with Atmega32A using 74157 Multiplexer and select pin of Mux is connected with pin 16 of Atmega32A. The Problem is that Mux is not passing gps and gsm data to microcontroller. i have checked the continuity of traces all are ok. a proper voltage 4.9 is avaliable on MUX select
Post your code and hardware interfacing circuit. IF you feel everything is OK then try to increase the delay after sending AT\r for minimum of 800ms.then read the recieved data. - - - Updated - - - Post your code and hardware interfacing circuit.
