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 (...)
do you receive anything from the modem when you expect an sms text? for example, could ou be loosing received character because you are not reading the UART sufficently fast? what baud rate is the SIM 300 ? are you using polled or interrupt receive on the UART?
Hi everyone in this forum.Again I come searching for help.On my first post I got direction on how I can write program to interface gsm modem to read and send sms.

hello, everyone thanks for all of the contribution each and everyone provides in this forum. I'm on the process learning how to program pic microcontrollers using "MikroC Pro for pic" software.Till now I have some ideas on how to write programs .

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 (...)
Send "AT+CNMI=2,1\r" once initially before entering while(1) loop. After issuing this AT Command if gsm modem receives sms then it will send out response +CMTI: "SM", x where x is the sms index in SIM. If memory is used then you get +CMTI: "ME", x You have to parse this response and extract x and depending upon the value of x you have (...)
No, you don't need Zigbee/XBee. You send sms to gsm modem with SIM card. Then say at every 5 seconds you read the say first message (message index of your sms) and then parse the message and extract the command you sent through sms like *Device Off*. Based on this command you control the device (using Relays).
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 (...)

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. To avoid complexity I planned to use pickit2 UART tool. I connected UART Rx Tx with SIM300 Tx Rx. But it is not working. When I send AT command it (...)
