SMS based Device Control using AT89S52 & NOKIA 3310

Hi All,
After 2 months of extensive efforts,I have completed this above mentioned project.People have had SMS contl on Siemens/Ericsson/and other phones but they have a modem on them,and comapratively simpler coding is needed.Older nokia fones use
FBUS protocol which is their (nokia) own difficulkt protocol made up of innumerable bytes @ 115kbps.Some sites like www.embedtronics.com give a detailed description on the protocol. also www.gnokii.org have done commendable work.
But all other people have done it with AVR(with larger RAM).I have done it with 256byte RAM on 89S52.I have 4 devices (relays) which can be controlled(on & off).
I will not give the source code directly,but can help u in the process,if u r well read and know a bit of 51 and programming.
and yeah,thanks to Ajay for creating such a site

Thank you so much for the complement and i am happy that i could help you
And would you like to make an FBUS library and we can have it on our site? what do you say? general routine APIs?

instead i'll put up the hex code,general ckt and most important -->an excel sheet(which i had made for myslf from sites like gnokii and embedtronics) which explains the FBUS in details.these fbus commands definitely will make life easier (believe me...its a hell xperience to understand the protocol in itself)..

[ I take back my words! and apologize for any mistake ]

Thats the reason Rickey's World is here.. complete information and i don't hide anything i work on.. soon i will be posting two projects based on IR remote..
and of course those will be open for all...!

this is gr8 ajay that the words came out frm u,
or i was about to write the same thing.

there is gr8 support for fbus protocol over a wide range of nokia cell phones.

a little googling will show loads of them.

we are here to share our experiences and let others benifit from them.

yeah first binu fight with me because i posted his project.. anyways that was some other issue.. lol these things disappoints a lot

oh man lots of claims and blames there.i actually wanted to help everybody out there wanting to learn the FBUS.
I want to clear some things here.
1)As shyam said there is lots of support on FBUS and a li'll googling will help u on this,but he has failed to understand that he wont find stuff for 8052.Nobody(not even embedtronics.com,which I mentioned) has direct info or the codes for FBUS,which I think I have uploaded in my earlier posts.If I was the stingy "Indian" as Ajay has notoriously christened me,I would have hesitated to even put that up
2)If somebody is there to help u out and he says he will be with u during the hardship,u shud be happy and proud of his company.If I were to give away the code,wheres the learning process?..instead I m saying I will help in every which way to let u understand the working and coding..
3)During my development I tried to get info from wherever i could.I asked Ajay too,about the FBUS,and Binu too(who incidentally has just copied all his projects,including the sms and nokia5110 with AVR from a reputed magazine).But no one has knowledge on the subject.If only sumone was to help me understand the protocol,my development time wud've been reduced a lot.And thats wat i was proposing to do.
4)Like Binu,I was not denying to put up all the necessary material to build this one.I said I will give ckt schematics,cable schematics,and the hex code,so that anyone wanting to build the proj for hobby can do that immediately,and if someone who really wanted to do that for college or sumthing,I will help wherever needed and was ready to SHARE MY EXPERIENCE .
....But alas..Ajay..u have failed to understand my intention..and forced me in a cocoon..

I am sorry? :-|
I didn't mean to hurt u.. but i was just putting my point forward.. Maybe you should have explained this in your post before.. Well i can say is i am extremely sorry. I was just talking about general public.. nothing much..

Hey.. i want to apologize and want you to teach everyone about FBUS. So All i can do for you is.. you tell me what you did and i will make a tutorial page under your name..
This is just an apology from my side.
I don't want you to give exact codes.. but i wanted to you to guide people with the FBUS frame format, how to generate checksum and all that.
After that if you can then good otherwise i will assist you to make an FBUS library.. this will be the only first library ever written for 8051.

I cannot tell you how many things i have right now in my portal PC to share with people. But i don't get much time to write and make webpages. Soon i will also be releasing library for Nokia Graphics LCD used in Nokia 3310 mobile.
which cost only 150Rs or less and give you best results. Also there are few addon stuff which is only for users of Rickey's World.

I can understand how you might be feeling right now.. all i can say is.. Please forgive :blush Its not that saying sorry will make me feel bad but rather.. i don't want to hurt anyone for no reason. Please...!

hi abicash,
forget the previous comments buddy,
looking forward for ur help and upcoming posts.

yep... i think we got too much aggressive..
maybe its because we are too keen to learn FBUS.. and he is teasing us! so just have to wait a lil more..

@abhijit
Are you ready for an FBUS tutorial? In our Microcontroller Interfacing Section? [ experts comment needed ]
