Interfacing MICROCONTROLLER WITH MOBILE

I need Some information that how to interface mobile with microcontroller (89c51) I have a serial cord and i know i need to use max232 in between but the problem is the commands which i m need to use to send the sms from UC to the Mobile ...!
awaiting for quick responce
Thanks

Hey hi! I think a few days back we had a CEan facing the same problem. Interfacing the micro controller to the mobile will require an interface of RS 232.You need to use the 'at' commands. Go through microcontroller books.Its easy if you get the right book. 😀
hmm well Thanks for the Reply
But If u know any book which is of my concern so please post reply with "book name"

You can test mobile with AT, it responds with OK

Then you can enable the text mode with AT+CMGF=1, to enable text mode and wait for OK.

Then at AT+CMGS="+91__________" ,fill in with phone number, you will get a > prompt and here put your message followed by ctrl+z.

If you get OK, your message will be tramsmitted.

You can use AT+CSQ to test signal strength.

Well lost touch with techie books.. but i think you can find ample info on net.I know you will ask about the links.Visit the wikipedia I think it has all the AT commands.

I dont know why the link has been removed, but wait for it. I have asked the moderator.

And till you wait here, why dont you search google or some more sites before asking vague questions. Look into the matter and then formulate your problem. It will be easier to answer that way.

hey to connect microcontroller to mobile u need not to use MAX232....u can directly connect mobile with microcontroller serially.....but remember the mobile device must work serially.....not usb...so if u have mobile which accepts data serially then u can connect directly to Rx tX pin of Micon..

I am not sure about RS232 connecting and working on nokia phones... but I can think of another way... why dont you use a bluetooth device along with the microcontroller. With a little C++ programming you can connect to the microcontroller....

For more details on compatible bluetooth devices with your uC check with Atmel and if they have any costomized one... even if they dont have one ,you can always use a standerd blutooth device along...

for program logic and code... check out a similar project described at :

Some terms that will help you on your quest.

Noka uses a protocol called Fbus, which I believe is just inverted serial communication.

If you want to make it easy I know there is a particular sony-ericcson phone out there that just does standard serial communications. You're gonna have to learn their AT commands.

There's a couple documented projects out there with the sony if you google that stuff.
