I have recently suffered from the same issue.. but my modem was TC35i of sainsmart. I changed the modem 2 times because of this issue due to lack of time. Your may check PC to modem COM port, equal Baud rates and other parameters such as stop bit flow control none, Use hyperterminal. Ask...
Thanx alot my bro for helping... But yeah I am in REALLY hurry its LAST WEEK for submition. I am still stuck on how would I make an LED Light up by SMS. My Modem does communicate with MCU with responding to AT commands and indicating other LED lights. But I need to make it READ SMS in such a way...
very thanks for the good knowledge... can you please let me know how can we define RI and SBUF in your post...
Im not acutally cleared with how to do it... I am using mikroC and my code goes something like:
#include "LCDdrive.h"
char uart_rd;
char output;
void main() {
LCD_initialise()...
Hi there.. I have made my C programming code on MikroC which is able to communicate between Modem and Microcontroller PIC16f877a. It is successfully sending AT commands to modem and modem responds ok which is indicated by LED lights connected. I need some assistance on how I will program it to...

Thanx alot bro for such a good knowledge. What happened was that my modem stopped communicating. I ordered another which worked great but the next day same thing happened and stopped working even. I am using rs232 Interface board with MAX232. My communication was working great with MCU and Modem...
Thanx bro what happened actually I ordered another TC35i Modem of Sainsmart.. It is written that it Supports Arduino. What I am using is PIC microcontroller. I was wondering is fine for my controller as though it still is a AT commands control GSM modem? well yeah I already used the same modem 2...
I am working on GSM modem TC35i Siemens... with PIC16f877a... programming the code as I learned from some sample projects..but still didnt get any output.. here is something what it looks like:

Thanx alot for such a good knowledge... I have started to work on the code... the source file which came along with the modem contains the header file of #include reg52. but that works for 8051 micro-controller as I am using PIC16f877a. But well yeah I started to make the code which is some...
Hi,
I have started working on the code to program the PIC16f877a connected with GSM modem TC35i and an LED board. I need have a start up for the code what header files should I include and how would I control the LED's by giving an sms. i will be waiting for assistance. Thank you in advance.
well thanks... yeah I am also going for this modem. But from a UK supplier. :)

Thanx.. Yeah I am just about to start my programming in C++. I am not sure of using labview because didn't use it before. I will use a compiler such as IAR embedded work bench
in which I will...
Thanks for being so helpful. The modem part if I get of sim900 as : then any idea how to complete the circuit ? Do i need a separate power supply + Antenna + Sim holder or anything attached ? will I need to solder and assemble all the parts... or is there any complete modem to be attached with...
milind.a.kulkarni :Thank you for the good knowledge. I am currently using PIC16f877a by "eblock matrix-multimedia". The GSM modem of eblocks have stopped coming so my supervisor told me to order another one. Is the sim900 one capable of it? Is there any programming issue or difficulty with it...
