Success

Thanks for the support.
Now I am able to read my SMS continously on my LCD. It was a problem related to Serial communication. An overflow error was happening . Now I just clear the flag continously.And I can readthe SMS continously

thanks fo the reply...
can u pls tell me how much does a gsm module cost?
i've heard that F/M bus protocol used in nokia mobiles can be used an alternative to gsm modem?wat is ur opinion?

 

[Ratheeshbr]

GSM Modem cost

The modem costs from 3000-5000/-for a single quantity.
I too read about the F bus. but haven't used it. We need only 4 wires for the communication. It will be easier if 3310/1100 is avialable

 

[athul]

thanks...
does anybody else know more about F/M bus communication ..pls reply....
is it necessary to have an exta modem in the mobile for sending messages by AT commands...

hi Sathiesh Kumar

i have the same problem on interfacing between PIC and GSM , I'm happy for you as you solve it

Hi to all..
At last i have send the sms using a microcontroller .. thanx for all...

as the others help you on solving it , can you please send the code that run with you to all of us can use it
waiting for your replay
thanks in advance

Hi Kumar!
I am having problem as you did, that i can't able to read sms form the mobile!
Would you give me some advice
Thank in advance!!!!
(I use mikroc as you)

gsm modem

how can i connect gsm modem to microcontroler
please anyone help me out from tise problem

 

[kubeek]

UART usually does the trick.

 

[patidar_sachin]

thanks for replay but i want c code for reading and sending sms by gsm modem
please hepl me

Hi,

I read this post. I am trying to do something similar. However I am using an IRIS mote which works on tinyos platform and I am trying to interface it with a GSM module (ADH8066) from sparksfun.
I have the GSM modem working with AT commands using hyper-terminal.
I also have the UART interface between the IRIS mote and the PC working with the mote sending AT commands to the hyper-terminal. However now when I connect the mote and the GSM modem, it does not work. I have checked the power supply for GSM modem which seems fine. All the baud settings are also correct.

I am not sure what I could be missing..Could it be something to do with CTS,DTR ?Can anyone please advise me as to how I should progress? It would be of great help.

im working on the same..will u plz send me ur code..this is a part of my final year project..

Why can't you write your own code?

All you need to do is learn how to send and receive from a UART.

If it's for a final year project then you should really be researching how to write it, not get someone else to write it for you, this is a forum to help people, not do their work for them!

However, I'm sure if you paid someone the would write your entire project for you!

This thread is basically 8 pages of RTFM!

Start with the AT Command set for your module, interface with Hyper-Terminal or something similar, then move the code to the micro!

I am trying to receive messages through gsm+pic on hyperterminal.i have already done with sending part.can anyone give me some idea how to proceed for receiving messages through gsm on hyperterminal...

 

[Ratheeshbr]

@shuchi sahay

You can connect your GSM modem to PC and send SMS to the SIM within the modem and You can see the messages on Hyperterminal

 

[Ratheeshbr]

What?

 

[shuchi sahay]

hiii..

I am working on two way communication using GSM with pic16f877a microcontroller. I am able to receive msgs on lcd through gsm without reseting the microcontroller i.e one way communication.I have done with transmitting part also through gsm n able to receive msgs on mobile .now when i go for two way communication i.e receiving+transmitting at a time, its working nicely.But after each cycle i.e (receiving+transmitting) i need to take out the receiving pin of gsm,i reset microcontroller n den i again connect the receiving pin of gsm with microcontroller.after that i can again receive n further transmitt msgs.i dont want to do these changing of pins and reset controller ,physically.it should come mannually.so please help me regarding this problem.

Thanks With Regards.

Hi,
I hope your buffer is getting full.
Whats the compiler you are using?
