I want to send received sms to other number so I want to copy that topmost sms in array & after that I want to send it using AT commands. Please can anyone help to out to provide the code for it in C?
Yes you can get informations about the input of the microcontroller on your phone. Read about sim300 or sim900, there are a lot of GSM modules which can be safely interfaced with the micro troller for calls and sms.
I am working on a embedded project using GSM sim300.i am using Atmel at89s52, GSM module ,temperature sensor LM35. Working of project- Temp sensor will sense the temperature and sent a message to my cell phone only if the temperature is above 30^c,,and if i sent a sms to the cell phone(for eg-OK),the relay connected to the microcontrolle
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; //

is it necessory to use this dialler to make call. Bcoz you can have good option of sim300 or SIM900. Because it is having connection of UART and also other protocol so you can call or sms on number.
Hi, i have interfaced the sim300 to hyper terminal. i made a call to other number & i got the call also. i received the sms. i read the all sms at once by using AT+CMGL="ALL" , but if i want to read a single sms by using AT+CMGL=1, 4 or 5 then i get the error as +cms error: 305. for writing a sms also i (...)
Try the following sequence AT+CMGF=1 ;;As u have used in sim900 also Now try this AT+CSCA="+XXXXXXX" //Set your sms Center's number, you have to check with your provider about this number And then Finally Do AT+CMGS="number"
I am doing a automation project to unlock door via sms. I am using an Arduino UNO and sim300 with a max232circuit in between. The GSM module to hyperterminal interaction is working, ARDUINO - MAX232 to hyperterminal is working. But when i combine them all, I don't get any result. I am using SoftwareSerial mySerial(2, 3) in my program. Is that
