how to interface mobile with 8051 microcontroller....

I am doing a project which needs a mobile to be interfaced with the microcontroller kit....The kit consists of LCD dispaly,serial port.and all ...the kit which we use in our colleges...(exel technologies kit) if anybody suggest me how to interface the mobile thru the serial port of the microcontroller kit.....plzzzzzzzz help me....

Use mobile phone which support AT Commands. you can directly connect that phone via datacable to your microcontroller kit at a baud rate of 9600 and you can send AT commands to your phone to read and send sms.

The first thing you need to do is find a mobile phone with AT Commands. Recommendation is use sony erricson's 290i

what are AT commands?how they works

@amit,

AT called 'attention' commands are a standard set of instructions used by the host to communicate with a GSM device. Try googling for more info , u will get tons of info.

hey!!!!i've a question.....can v use a simple data cable tht comes packed wid a mobile phone....or do v've 2 use RS232 Cable...wid one end connected 2 COM2 port and other 2 mobile phone ????

well RS232 is the only interface commonly supported by most of controllers. So, you can only use those phones with com port interface.

i dont thnk so tht new upcoming model supports any COM Port interface cable...

yep, so true. So the only option is to find a old second hand cheap model. ,
the silver lining is that atleast u will not do this
:mad :mad
if something does go wrong and ur mobile burns out

I would suggest everyone to start using GSM modems now.. coz that the only last hope

I'm sure if you go to any cellphone repair shop you find that they have piles of old spares/scraps you could a build a working mobile from. I got some funny looks from them when I asked them for it, but flash a little green and they'll be happy to part with a few items that have no marketable use. I've been quite successful in this way lately.

Just remember to use a MAX232 if you going to connect the cell to the PC.
