Which gsm modem ? SIM900 ? Where is AT+CNMI=.... command for new sms notification ? UART1Read() returns only a byte. What is the Crystal frequency ? I can give you the code but not for 16F877A because it has less RAM and mikroC PRO pic doesn't generate bank switching code. To receive AT+CMGR response you need a big array
i am working on my project that switches off and ON home appliances using an android app that creats sms .The app can also request for power being drawn by the appliances through sending texts request that can be red by a gsm module. My gsm module is linked to a pic 18f4550 and my gsm module is a sim 300 (...)
gsm is used only to send sms ? If yes, then connect 5V TTL Rx pin of gsm to Tx pin of pic. Connect 5V TTL Tx pin of GPS to Rx pin of pic. If gsm is used to send and receive sms then use pic18F46K22. It has two UART.
Here I am attaching Tx code. Tomorrow I will post Rx code. Pressing the button will send the sms. Change mobile number and compile the code.
Hello... I made temperature sensor using pic16f877a. NOW i want to send this reading using sms... i want when i send for example "Temperature" to the phone connected to the pic it responds to me as message "Temperature is: 20°" i mean sms communication and i guess it is done by fbus and AT commands, my problem i cannot (...)
Hi.. I am using pic 16F877A Microcontroller and SIM 300 gsm Modem Actually I can send sms using SIM 300, can receive the message location and displayed that on lcd. Everything works on hyperterminal. But in hardware i couldn't receive the message from the modem.I couldn't find the problem..
what is your objective?? what you want to achieve? and what new AT commands you have included in your code? as your thread says sms interface, and in last point you said that code for only sending sms works fine. so now what are you trying to add?
there are many posts on using gsm modem to send/receive both sms texts and TCP/UDP packets do a forum search on gsm modem
dear friends, i used pic18f4550 for sending sms through gsm900. i got the at commands correctly in hyper terminal. the problem is ...... manually i send the AT commands from hyperterminal to gsm900, the module is sending the sms to my mobile. but, gsm module is connected to (...)
how to request sim900d for new sms.(i want to check if any new sms is receives ) . I am working on pic16f877a using CCS compiler
I would also suggest you to read the basic AT commands for sms(SEND,READ,DELETE,sms INDICATION)/GPRS/CALL REJECTION from the manual.. Before connecting it to the MCU, pls connect to the hyperterminal, and try various AT commands... This would give you a basic idea of how a gsm works and the reponses it will give... Based on this you can (...)
Hi all. I interfaced gsm modem with my computer using hyperterminal, it works fine for reading, sending and deleting sms. But when I connect the same gsm modem to pic18f46K22, I don't get any response from it. I have interfaced 2*16 LCD to see the sent commands to the gsm and to view the (...)

Kindly find below: i'm programming a code by pic 18f4550 with sim 900 gsm using Mikroc pro. my problem is i'm beginner in this field so i want your help. program functions are : 1- send sms depend on action with gsm place coordinates , i don't use GPS module. 2- set some status on a web service. 3- if i (...)
I use the following function in my program to send sms using pic18F4520. It works fine for me. I am not taking any response from the gsm module. If you want response you can just edit the code. void Send_sms(){ UART1_Init(9600); Delay_ms(100); UART1_Write_Text("AT"); Delay_ms(100); (...)
Dear all, I am doing a project to send sms when states of inputs changes. I thought of using USB type dongle. I am using pic 16F88 . Can I connect pins of TX and RX of UART port of pic directly to TX and RX pins of dongle.? thks
I have a gsm module (SIM300cz) in my hand right now. I want to test this module by sending sms using pic MCU. To test the Module I wanted to interface it with my Laptop first.

I have written a code for send an sms from pic 16f877a via gsm module(New Siemens T35i) . Code is working in the proteus but when programmed it, tx output is around 5v and not changing. Help me to find out the problem here is the code i have used. void sms_send(); char sms; void main() { (...)
may be you never send " or 26 " at the end of your sms. while(1) { for(i=0;i<8;i++) { putchar(cmd1); //array "cmd" is gsm command "AT+CMGS" } putchar(0x22); for(i=0;i<13;i++) {

hi.. i have project moving sms on 16x64 matrix led using matrix gsm gdt11 model and 8051 microcontroller can any one help me in coding..??
@areeckal Even for PC you will need a gsm modem. There is no way that you can do it without modem. As for your topic title "How to send an sms from mobile phone to pic", it is very easy, Type your sms and press Send button :-) (sorry, could not resist) :lol:
Refer to "sim900 AT Commands Manual". Google it and look in the sms toolkit section inside the manual. Command for sending sms is: "AT+CMGS" --->> details will be available in the manual.
If output of your lpg sensor circuit is analog. Then, do compare of some limit value to send sms. How to send sms using gsm Modem, refer gsm code.
