Hi Nishant,

I have attached AT commands for my Wavecom modem here. But I think these AT commands can be used on most modems. Correct me if I'm wrong. I have no ideas on GM29 and I don't know if you need to install any drivers. For my Wavecom modem, I just plug in to RS-232 port and I first tried sending SMSes using Hyperterminal to get a rough idea on how the AT commands work. Maybe you should try using Hyperterminal first. I can't open the file that you attached. I only found a SendMessages.llb file inside that zip file.

To send messages, you just have to use the AT+CMGS command. For reading new messages on your SIM card, use the AT+CMGR command. Please refer to Pg 138 of the attachment to look at the format for sending a SMS. But all these commands are for my Wavecom modem, though. I don't know if your modem uses the same format.

Cheers,
Teck

Hiii,

       Thanks for the reply, actually the file i told you was inside that llb file, anyways left it, but can you send me procedure which continuous command i should write in the Hyperterminal to send the message, another thing i want to know is, which command i should write to set the message center number? i mean give me the exact frmat like at+csca+919898051914, is this a right format or it requires anythin else then this, cos i am getting an error if i am trying to do so.

Thanks,

Nishant

Hello,

After connecting your modem to the RS-232 port, use your Hyperterminal to open a connection to your modem. Type AT and press enter and you should be getting OK as a response.

For setting the message centre number, refer to pg146 and pg147 of the attached .pdf file. The format for setting the message centre number is AT+CSCA="+919898051914" (I think you need to include the inverted commas around your phone no), then press enter. After that, follow the instructions on pg138 to send your short message.

Please take note that whatever information I am giving you here is based on a Wavecom modem. I don't know if it will work with your modem.

Good luck with your work!

Cheers

Hiii, Teck

      Thanks for the help man, ya i have done the same thing as you suggest that, i had a look at the pdf file you sent and i also took a help from the internet, and my commands were work perfectly, and i had sent the messaegs to the other users also.

        Another thing i came to know that there are not much difference in the AT commands,which are common like send, and one you suggest was setting the message center number, this commands are common in general modems, it only changes, if company specifies this thing, o'wise, this things always run.

         But i still cannot do one thing is i could not read the incoming messages, i ve try to send the message from my cell to the card which is inside the modem, and i ve used the command AT+CMGR="n",where n stands for the sunctionality number which lists all received but unread messages, i could not read the messages, can you please help me for that?

Thanks & Regards,

Nishant

Hi,

For the read command, use AT+CMGR=n, that is, no need to put the inverted commas.

Hi All,

If I just have normal modem with router (Internet connection frequently on), does it still work?

Thank you,

[Nishant]

Hiii, Apple

                   I dont think that the modem u ve for the internet will do this, these are the modems of different kind, which have special slot for the sim card, so that you can do the messages.

Thanks,

Nisahnt

Does anyone have an example VI that communication with mobile phone using Nokia phone driver?

Apple,

Your questions are getting more confusing. When I refered you to this post, I didn't notice that you had already posted to it quite a while ago. Are you attempting to call a cellular phone from your pc or are you attempting to control your Nokia phone from the pc. Those are two different tasks. If you want the ability to call any phone, then add a GSM modem to the pc. The Nokia phone driver has nothing to do with that sort of task.
