i want to connect my nokia n73 mobile with 8051. cau u help me how to design a cable for it, which can connect these two(microntroller and mobile phone).actually i am a beginner. i have a data cable with USB cable ,wiyh which i connect mobile with computers(pc suite).
at commands work properly with hyperterminals, but i want to connect it with mobile.
thanks
A USB cable will require a USB host - pretty unlikely on an 8051.

its so nice of u,that u replied. but i want to elaborate my problem . 1)-i am using nokia n73(which supports AT commands).now i want assistance in circuit diagram - how to connect my pop port of n73 with microcontroller, so that i can send at commands to read or send sms. pin diagram of n73 pop port :pinouts.ru/.../nokia_dku2_cable_pinout.shtml also :pinouts.ru/.../nokia_pop_pinout.shtml
2)- after that how the AT commands is transferred to micro controler? is it through serial transmission from microcontroller using TCON,SCON register programming?
3)- in hyper terminal we type AT and in reply we get OK by mobile. now in case of microcontroller will it be ASCII code of "AT"?
thanking you.
after seeing pin diagram of pop port(N73) i deduce that it is USB type communication. will it be possible to connect n 73 with 8051 and send at commands?
Didn't I mention something about that in my very first reply...?
thanks andrew.\:) but what is the subsitute of 8051? is it pic controllers? do they work with usb interface?
You're missing the point!
The point is that you will require a microcontroller with a USB Host. That means both a Host hardware interface and a Host software stack.
This is not trivial - are you really sure that you are equipped to tackle this?
if i connect 8051 at com1 & phone modem at com2, then is the communication between com1 & com2 using hyperterminal(or any other software) possible or not? in that case microntroler 'll be made tx and modem rx....
Yes, of course you could do that - but what would be the point?!
You might as well get rid of the 8051 completely, and just use the PC!
basicaly i am designing a home aplliance control system.(HACS) in which some sensors keep an eye on some parametrs like temp of room,smoke sensors(which will detect fire) and these sensors will be interface with microcontroller(i know abt 8051 only) and if any smoke is detected then microcontroller will send a massage to other phone (eg.fire brigade). now my problem lies here. how to send a message through controller using a mobile phone(having modem,i have nokia n73)? through hyperterminal using AT commands i have sent sms to other mobile,but i want it to be sent automatically through controller that "fire is detected". ............... i planned for two conections , one between microcontroller & hyperterminal- AND another conection between mobile phone and hyperterminal(with same pc). now- microtroller will send "at commands" through serial port to hyperterminal, and hyperterminal transfer these commands to mobile modem, which will force mobile phone to send required sms acc. to situation.
You DO realize that SMS is NOT a real-time notification method. It is dependent on the network. You may have your structure burn to the ground before you get a notification.
