    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

    UART usually does the trick.

    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.

    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!

    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

    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.
