Hello all, I am planning to do a small project where i would like to send SMS from my mobile phone to control a stepper motor connected to my 8051 port.Is it possible to do it?i am using nokia 6230i mobile.I am using Keil MCB x51 board for programming. if there is any example code or link where i can get it it will be very helpful to initiate my work. Looking for your help. K.Suvala Looking for your help.
I haven't done this (at all), but you might look into Kannel < http://www.kannel.org >. I believe you'll need a second phone, one that can act as a modem for SMS messages. Kannel interacts with these phones and can interpret the messages. The phones in the middle column < http://www.kannel.org/compatibility.shtml > are the currently supported modem-type phones, apparently. Of course, Kannel probably won't run on an 8051, but perhaps you won't need something so complex anyway. Good luck.
See: http://www.8052.com/forum/read.phtml?id=106640 Remember that there is a significant delay between sending an SMS, and it arriving at the receiving phone - many seconds. Also, delivery is not guaranteed. This doesn't sound like an ideal solution for motor control - what exactly is your plan?
"you might look into Kannel http://www.kannel.org . I believe you'll need a second phone" I think you have the wrong end of the stick! The idea of a gateway like Kannel is to allow sending SMS from your computer network, and/or receiving SMS into your computer network. If you're using such a gateway, you'd have just one phone - acting as the "modem" on the 8051. If you have 2 phones, you can send SMS between them direct, so there's no point in having a gateway!
