u need a phone with Serial port connection so that u can test it on hyper terminal. so search for phones like nokia 6110 etc.. i am not sure whether it support AT or not just giving you an example.

So make sure whichever phone you are buying or getting it. it must have serial port Data cable.

hi ajay,
i have checked some cell phones but only one of them is responding to AT commands through hyper terminal. i have checked commands AT and AT+CPIN? .AT shows ok and other command shows ready.now the problem is that i dnt know abt the Rx and Tx pins on cell.And i must tell u that cell is T29s.
plz tell me what to do know.plzzzzzzzzzzzzzz

you can connect your phone with the microcontroller via same datacable and connect that phone with the help of max232, just as a normal serial connection. I hope you understood.
now do one thing... search and download the AT command manual for T29S or Sony Ericsson (i hope i am not wrong with the company name) mobile phones.
and try with the commands for reading sms, deleting sms, sending sms and check what you get in the terminal. if possible copy paste the results of whatever you do in the terminal in the forum as your reply. So that i can explain you more and in a better way.

First of all you must use 8052 because there are two types of interface available AT command based interface which runs at 9600 baud rate and FBUS interface which runs at 115.2K Baud rate.
if you can get a mobile with AT commands i will help you implementing your project.
so first of all... search in the net for any AT supported Mobile, buy that mobile doesn't matter it is a second hand.
INFO: all mobiles with modems support AT commands
if you want to check the mobile whether support AT commands or not..
then connect the mobile with Hyper Terminal
at 9600 8-n-1
in the terminal window type "AT" without quotes.
you will get a reply from the mobile as "OK"
this is how you check.

hi ajay,
i have tested the following commands on hyper terminal

AT //testing
OK //output
AT+CPMS="ME" // selecting memory of mobile
+CPMS: 1,25,25,25,1,25 // output
OK
AT+CMGR=1 //reading sms at first memory location of mobile
/* i sent the message 10101100 ,from other mobile, which appeared at first location
of my mobile and when i entered the above read command the output
is given below*/
+CMGR: 1,,26

OK
continued...

AT+CMGD=1 // command to delete the message which i have at first
//mermory location
OK // with this output the mesasge in my mobile at first location
// was deleted
so are these outputs ok??? what more commands should i learn??
and also i have found the pin configuration of data connector for my
T29s,, now tell me if i need to use max232??? i think i dont need it
becoz all the process will occur at TTL.plz reply

messages are sent and received in the PDU format. so you need to understand the PDU format.
for this you can visit
http://www.dreamfabric.com/sms/
http://emctone.tripod.com/html/smspdu.html

usually we use 7-bit octets for normal message when we are not using any special characters. so you can see those websites for complete description. and for programming part, you can create a structure and distribute the message and decode the message part.
hope that helps for now u can just understand how this is to be done.

hi ajay!
how are u?? i was bz in my exams dats y i was away from forum and my projects.yesterday i tested my program with my circuit but unfortunately there was no response from cellphone!!
i want to ask u dat when i transmitted AT and carriage return from microcontroller...will cellphone transmit OK or somthing else???
i directly connected the rx and tx pins of controller to cellphone pins.
but there is nothing.i dont understand where the problem is... code is same as i posted u before. plz give me some idea!!!!!!!!!!

well you first need to test your program on the PC.. i mean.. simulate it.. you become the phone.. connect your hardware to PC and in hyper terminal you will get AT commands you give the reply to your controller and see how your controller replies.
this way you can check whether you controller is doing exactly what you want.. i hope this will help you

forgot one thing.. in your connections.. u connected RX and TX but what about GND? without that nothing will work...!

I am a step further in implementing the s/w on my h/w.I'll xplain in steps and thn my questions
1)I developed the s/w to send the init char 'U' 128 times and then the init string(to get h/w & s/w version of fone) of 10 bytes and waiting for the fone to answer back//all this in Keil and run it on Proteus simulation s/w,and it runs fine.(A baud rate of 2400 bauds was selected for this)
2)I have a data cable(FBUS) which connects to my 3310 to PC.I hv connectd my at89s52's Tx/Rx to a DB9 conn's(Tx/Rx)in the same ordr thru a MAX232.Now Max's Tx/Rx go to PC Rx/Tx (cross).(how do i send/attach my ckt dia?)
Now some things happen,rather dont happen...
1)On portmon(s/w to monitor serial port) nothing shows up after I run my prgm.
2)logomanager(pc suite to download logo/sms/etc to 3310) does not show fone as connected.And nuthin seems to b running.
3)On CRO also Tx/Rx are shown high(idle state)
4)hyperterminal does access the serial port though(but irrelevant of the target board)
My q's
1)in ur proj,what baud rates did u run the micro?as i see u hv some 7mhz crystal.is it mandatory to run it at 115kbps in accordance with the fbus rate?
2)what do u think may be wrong with the cable,which whn connectd to pc directly does show fone as connectd and whn done thru my ckt,does not.
pls reply cos i m stuck at this place

Re: sms controller using nokia 3310 FBUS Protocol

contact@nospam.com (Ajay Bhargav) — Wed, 01 Aug 2007 02:00:40 -0700

As far as i know... F-Bus runs at 115,200bps not 2400... so i think you must check the speed. Also there is a condition for F-Bus that, the data terminal ready (DTR) pin must be set and the request to send (RTS) pin cleared.
Hope you take care of these things..

Regarding attaching image.. or circuit.. do the following steps:
1. upload image to www.imageshack.us
2. copy the direct link to image
3. and put image link in [img] tags
for example:
[ i m g ]link to image[ / i m g ]
please remove space from the tags i.e. [img]
4. thats all...

I think something is wrong with your cable. did u try using a datacable? its easy.. to use it.. check if your software is working.
and i forgot to tell u
you can achive 115.2Kbps on 89S52, use timer 2 for baud rate generation and crystal used is 11.0592Mhz

contact@nospam.com (Ajay Bhargav) — Wed, 01 Aug 2007 03:32:27 -0700

hey thx for the reply...
can 115kbps be generatd using 89s52?
the thing u said about setting DTR and clearing RTS is just reqd for the FBUS cable,which has active electronics in it and so as to power it up,these 2 pins r needed(whr setting/clearing means DTR=+12V,RTS=-12V).I jus need to knw few things.
1)whn i connect micro-->max232-->fbus cable
-->PC
PC wud not detect any activity on its serial port(PORTMON)
==for this I did this
a)made PORTMON active
b)connectd the FBUS cable(with DTR=1,RTS=0)
c)to jus chk ,turned on LOGOMANAGER (for nokia 3310)
but it shows phone as not connectd.
d)but whn i directly connect the FBUS to PC,Logomanager shows fone as connectd,and voila...PORTMON starts registering the activity
2)whn i start hyperterm and access com1,it will show sumthing on my micro(seen thru CRO)
all my routines of transmit and receive r running smooth in PROTEUS

Re: sms controller using nokia 3310 FBUS Protocol

contact@nospam.com (Ajay Bhargav) — Wed, 01 Aug 2007 03:47:19 -0700

well.. i used Logomanager to analyse the FBUS protocol. using the datacable for Nokia 1100. I used software called... "Serial Port Monitor" from HDD software.
I checked the status of pins RTS and DTR. the status shown is same as i explained above for FBus. Yes this is to enable the FBUS in case when you are using a data cable.
But you might be using some special cable just for FBUS. maybe..
to monitor what is going on your com port better you also download this software instead of just looking at CRO. So try using the "Free Serial Port Monitor"
Link: http://www.serial-port-monitor.com/
tell me what you see on the monitor.. the data sent and received etc.

but whn i replace the statemnt by c='U'; hyperterm wont show anything.
am i doin anythin wrong?

but now my bigger pgm of sending 'U' 128 times etc and waiting for fone to send back etc is runnnig fine on hyperterm.
I m about to connct fone now...and as u suggested,i am cutting off the electronics wala part from tht cable and putting my plain DB9 conn,so its just a plain data cable now

hey
my FBUS cable which I got from a local shop here connects to the nokia 3310 below the battery(since that fone does not hv a std connection anywhr )
The other side,which connects to PC RS232(thru DB9) houses some elctronics,which whn i dismantled,had some diodes connctd to DTR n RTS,which work as rectifiers converting the +dc and -dc v/gs on both pins.This dc v/g i.e.+3V is to power up the buffers and/or max232 ON THE CONNECTOR(not on my board).
Now this phone side connector(which is quite unik) has 4 pins.which r MBUS,Tx,Rx,GND.of which MBUS is disabled.and Tx is shorted to gnd.
Now wat i m planning to do is:remove the PC side electronics wala DB9 and put a plain conn instead,using Tx,Rx,GND..to respective pins on fone side.
Now coming to ur post "it will be better if you connect using a datacable and use two extra pins of MAX232 to control the DTR, RTS signals."
what do u mean by this?...since I m not using DTR RTS,y do i cntl these?
the MAX232 on my board now is just to monitor the hyperterm/serial monitor..and the micro communication!
I m connectin the micro Tx thru a v/g divider(to convert 5v to 3v) to Rx on fone.While Tx on fone connects direct to Rx on micro thru a currnt limiting R.
and since I dont knw much bout 115kbps,i m searching..mayb u will help...

man i figured that out...using timer2 i got comm on hperterminal..i m not able to receive any chars...lets see!

but with 52 its possible to receive 115kbauds na?(i m defining i/p buffer len as 50)

Re: sms controller using nokia 3310 FBUS Protocol

contact@nospam.com (Ajay Bhargav) — Fri, 03 Aug 2007 03:19:25 -0700

long but a nice post..
with 89C52 you can get 115.2Kbps baud rate you need these values to setup..
RCLK = 1;
TCLK = 1;
RCAP2H = 255;
RCAP2L = 253;

after loading these values the serial communication will be done using Timer 2 at a baud of 115200 bps.

ok regarding what i said in my previous post.. i just wanted u to use a datacable instead of just some cable. anyways as you have decided now.. to connect to TX and RX directly... so i want to recommend you one thing.. its better to use a 3V zener diode across the circuit when converting from 5 to 3V. that will ensure the phone will not burn

as now you know how to get 115200 bps you must program your controller to talk to your phone at this speed so FBUS communication can be possible... because...

FBUS runs at 115.2Kbps

Re: sms controller using nokia 3310 FBUS Protocol

contact@nospam.com (Ajay Bhargav) — Fri, 03 Aug 2007 04:20:46 -0700

well don't do this way... i mean..
in case of phone.. its always good to use lock step method..
i.e.
Send some command
receive response
send command
receive response..

like that ways.. because you are sure that when u send some command thing to your phone its sure that you will get a reply.. only if the command is correct. Have you checked the FBUS protocol information on Gnokii (http://gnokii.org/)?
its the best place where you can find complete information of command etc used for different phones supporting FBUS protocol.

so after you send some 10 to 15 'U' send the command.. and you will surely get a response... if you are correct.. i actually tried doing this manually... by sending command to Nokia 1100. and it replied with the phone's IMEI number.
there is a software "terminal" in the download section.. use that software to connect to your phone and send command manually.. because it also supports sending data in hex format.. so you can send anything you want.. try the protocol manually.. and see what your phone replies..

hey thx man for being ther...
i'll definitely try n protect the fone with the gud suggestion u gave(zener)
I m yet to connect fone to the s52 yet!
i m chking all of this on hyperterm and free-serial-monito.(thx to u)
i now hv set up hyperterm @115kbaud and the fone sends chars to hyper(runing smooth)
i also hv a code writtn to wait for chars on Rx(basically receive routine) .but the hyperterm just sits idle and micro doesnt receiv any chars.Wat this mite be?
for this i defind a recv buffer of 50 chars.is this sufficient?

Re: sms controller using nokia 3310 FBUS Protocol

contact@nospam.com (Ajay Bhargav) — Fri, 03 Aug 2007 04:47:31 -0700

yes thats the idea...(hv been to gnokii )
actually the protocol demands sending 'U' 128 times.
i did this 'send' on hyperterm.then as if to emulate the fone sending back info,i wrote sumthin in hyperterm.
now in the micro i hv written code to recv chars and echo thm back(xmit)...so tht the effect is ;;whn i write sumthin in hyperterm,it is seen ther(i.e sent by the micro)
so it is like waiting for the fone to sned back data and receiving thm.
so i got wat u r saying...tht send sumthn get sumthn...etc.
but i m doing tht on my virtual"fone" hypoerterm.
But u c this is not happening.is this related to higher speeds and in wait-cycles,the recv buffer gets full?

contact@nospam.com (Ajay Bhargav) — Fri, 03 Aug 2007 05:20:07 -0700

i am really not sure that its the case..
but lock step method is usually preferred... or what you can do is.. use interrupts..
have you analyzed the protocol using any software on how phone works? see the protocol working with the help of serial monitor.. u will get to know what things are needed.. and what has to be done..
I mean once you see how things are working on serial monitor you will automatically catch up what you have to do in your program. I think you must spend time with softwares like some phone manager that support 3310. and see what commands they send.. note them down.. and try sending manually to the phone. i am sure you will help yourself that way

Re: sms controller using nokia 3310 FBUS Protocol

contact@nospam.com (Ajay Bhargav) — Fri, 03 Aug 2007 06:03:00 -0700

no ajay u not getting wat i m saying
forget the protocol for the time being.
now lets go stepwise.
1)send char 'U' for 128 times
2)send a'get version' string of chars (this is to get the h/w and s/w version of the fone)
3)now fone sends back some ack and the data we requested.

now i am NOT connecting fone.instead of fone its the PCs hyperterm.
now whn micro is reset,a string of UUUUU...(128 times) seen on hyperterm...thn the init string (0x1E 00 etc) ALL THIS ON HYPERTERM
now to simulate fone to send back data...i use hyperterm to send back any(absolutely any garbage) chars (which i can type in hyperterm)
on micro,whn these r recd,it xmits back thm (so tht can be seen on hyperterm)..this is to just test the concept..if working rite...
here yar...it is not working...is sumthin wrong wid reception?

yeehh!!! congrats..!!
well you can watch.. just like what you did here.. u can do on the real circuit too am i right?

hey also.. i want to tell you that... in FBUS protocol, to keep the connection alive, there is a string which is sent to phone after a repeated interval and phone replies it. also this acknowledgment sting is sent when you receive some data.. thats the reason you are getting the phone's software version reply 3 times, because once the phone send it.. it wait for an acknowledgment. if you don't send it.. it sends again.. phone do this 3 times, and if still no reply, connection closed....!!
so for sending another string u need to send 'U' again.. that is not good i guess so try to check what is that ack string for nokia 3310. use logoman to analyze this.

hi again ajay
Now all my pc to contollr communication is workin fine as i said earlier.
I now connected (with a lot of daring and fear) my fone to the set up.
Pls note tht the fone is connectd directly to the micro with level shifting(5v to 3v)
Now
1)I open up terminal on PC(for chking as usual
2)i ran the code..which sends sync char'U' 128 times.Then sends the 'get h/w s/w version' command with the hex codes 1E 00 0C D1 00 07 00 01 00 03 00 01 60 00 72 D5
3)here we expect the fone to send back 1E 0C 00 7F 00 02 D1 00 CF 71 followed by actual data
...but yar this fone isnt responding..at all...the terminalv1.6 on pc only shows the chars xmitted by micro..wat do u think?

well.. i checked your circuit.. and i see that you're using proteus..
you need a pullup at the phone TXD side.. after resistor R3..
connect a pullup to 5V. so that the TXD signal is also at TTL level.
and are you connecting the GND of phone too? if not then connect otherwise you will not be able to get any reply.
can you attach a copy of your code. coz i am lazy to write it

yes of course i m connecting gnd of fone.
and y is a pull-up needed?or do u mean that put a diode like in attchment....
here R4 is the pullup and see the diode

like this (mayb)fone is protected from the 5v.i.e whn fone is 3v(or high) the anode of diode is high at 5v.

and find my( code).c attachd

ok i checked the the datasheet, pullups are not needed.
in your code.. there is a problem.. in the init_port.c, as you are using Timer 2 for baud rate generation. then you have to set RCLK and TCLK bits. please make the changes and try again..

Note: don't get offended.. electronics is like this always you have to try try and try!

yes thanks ajay
i know abt the ack reply and if u see my code ,thers a provision for it.otherwise too,i have sent the readymade hex string "1E 00 0C 7F 00 02 D2 01 C0 7C" which is the ack frame sent "to" nokia!
After i sync and send the "get version" command,i come out of the loop and send this string,but still nokia's sending the version string(38 bytes) thrice..see, each day new problem!hehe
wat it actually shud do is send the ack frame(nokia to micro),38 bytes data string ,wait for ack from micro..and stop sending new version frames...but thts not happening.
wats logoman btw?...i'll just add the main() of my prg now

even after figuring the sequenc number thing,i m not able to stop the fone from sendin data thrice.
to chk i had done this...set a code of 10 bytes replicating seq no in third last byte.so whenever the phone transmitted frames with the specific seq no,it recognised ack and stopped sending.. but now i m not able to automate it jus attchin a clearer code

hi ajay.thx for being ther
but surely,changing the fone wont be of much help bcos i feel since both the fones work necessarily on fbus.u can definitely chk my code on ur 1100 and f/b wats happening
these r the chain of events in my code..
a)micro sends sync signal(xpectd: phone will sync-->:it does)
b)micro sends get version frame(xpectd:phone sends back 2 frames.1st frame is ack frame,with seq no present.2nd frame is actual data,with sequence no. as in earlier frame
-->happening)
c)micro stores this char. masks upper 5 bits,or takes lower 3 bits.(unsure whether happening actually)
d)micro continues to get remaining chars in the first data frame(56th byte) and stop.(unsure whtr happens)
e)the seq no is put in 3rd last loc of send- back- ack -frame.The even and odd chksums calculated
f)the frame sent in order to acknowledge nokia that micro has recd the frames.
g)if nokia recd this,it stops sending back 2 more data frames(with increments in sequen no.)-->not happening

now with above data,whn i dont calculte chksums etc and send a preloaded ack frame with seq no say "0x02",these things happen...
a)nokia sends back all three frames for 1st session--session is actual reset of micro--(seq no "0x40") for next session(seq "0x41") same...but now whn seq no is "0x42"(which is the same as our seq no) it jus sends the first frame and stops...hurray..it means its recd the ack from micro...
my q is.....
is it like this that micro is late in sending ack,so that nokia has already started to send back next frames?

long session.. ...but tell me wat u think

coz.. you know on FBUS, it says 128 times U, but i never get a reply after sending U 128 times, so i have to send this 128 x4times. after that the hw version string.. and i get the reply..
sometimes it makes me crazy.. on string works other doesn't and there is no free software which can be used to analyze this protocol. which has all the features of reading msg, deleting msg etc. Do you know any free software like that?

I was trying use AT commands, I´ve already success with a siemens, but I don´t know how to send AT commands from the microcontroller to nokia. I emulated a serial port (RS232) in microcontroller to send AT commands. Do you know if have something different to send AT commands to nokia?????...well, I think that I will try using FBUS.

there is an open source software called realterm. For serial communication. You can send data in hex format and also control DTR and RTS signals. use it to check the working of FBUS frames. see gnokii's description will give you idea on frame formats.

also download a serial port monitor software.. its also a good software to see what is being sent and read.

Hi Ajay, I´ve already found many examples of frames to send sms, receive sms..but in my project I need to make calls, receive calls and read the number that was calling....Do you have an example of this types of frames?

Nokia 6100 uses AT command which is simple to use.. i recommend working on it. because there is no information given online regarding frame formats of Nokia 1110.

Hi Everyone.

I am doing a project using AT Command. I am using Nokia 6680 set. I can communicate with my 6680 via USB by Hyperterminal or Proteus VSM. But I cant communicate via Serial port. I think there must be an initializaig command for enable FBUS. But I dont know that. thats why i cant make communication via Serial port.PLZZZ help me out.

I have a setup of phone -> MCU but before that i'm trying to make the PC work with the phone via a terminal software.

NOw i have an FBUS cable and FBUS phone(S) (1100, 2626, . ) so mobius works, i can read my contacts and sms with mobius so means datacable is okay. But when i try to send the commands in a terminal window, the following occurs.

1. I send 'U' 0x55 128 times. No response.
2. I send the frame for getting h/w s/w version.. no response
3. I send the frame for getting h/ws/w version .. no response
3. I send the frame for getting h/ws/w version .. I get the h/w s/w version in my terminal window 3 times! starting from the ACKNOWLEDGe frame..

What could the problem be??

Currently I am able to send and receive SMS using FBUS on Nokia 3310 using AT89S52. I am now trying to add support for Nokia 6510. My problem now is that Nokia 6510 will not send the received sms through Fbus once a new SMS is received. So that means the only way to get sms is by polling periodically.

What is the fbus frame that i should send to get new unread sms from the phone ?

I tried using gnokii using --getsms IN 1 but i couldn't understand which part of the frame is for getting new sms.

hi ajay,

the problem was in my program .. i have fixed it ... now i'm able to get the hw sw version from the phone ... but a new problem is bothering me ... in the 3310 data cable both the fbus rx and tx pins are shorted because of which the data i send is returned back to the pc ... this makes the programming a bit complicated (i have to drop the data sent by the pc before reading the actual data sent by the phone)... can i separate these two pins to avoid this ?? ....

thanks
bye

rx tx shorted? strange.. did u check on PC for this? are u sure everything is getting echoed? because if that is the case, phone should not work at all. i suggest u to check again.

make sure echo is turned off in hyper terminal or whatever tool you are using.

It works on my Nokia 3310. If it works on logo manager, then the cable should be fine.

Re: sms controller using nokia 3310 FBUS Protocol

contact@nospam.com (Ajay Bhargav) — Sat, 27 Dec 2008 23:40:27 -0800

ya .. they are shorted and the data i send is echoed back (and also the phone replies to the request(get hardware software version) i send ).. i use 'serial port monitor' for monitoring the serial port ... i think i can show u the log file of the serial port activities so that u can get a clear idea of wat actually happens... i am sending it as a private message to you .... pls check your inbox .. i'm also attaching the wiring of the cable along with that mail ...

i would like to tell u one more thing ... with the same cable, logo manager works very well .. i can send sms and can also read the contacts from the phone thru the logo manager with the same cable....

RX and TX pin should not be shorted. I build my on cable based on the schematic from http://www.panuworld.net/nuukiaworld/hardware/cables/fbus.htm

The software I use for testing is Eltima Serial Port Monitor

Some Nokia's used M-bus ,some F-bus and some both.
M-bus transmits and receives on the same pin.

Some cables are switchable(and some badly made). Just a thought

I want to program the micro controller in a such a way that the mesage center number is read automatically from the phone before the message is framed and sent ... (user dont have 2 enter it manually each time the service provider is changed)

By the way, did u find out anything about the RX TX short ??

must be a problem in wire i guess.. you can open the backpanel of datacable to check the electronics behind it and find out why its showing short.

regarding message center, visit this page and search for "Get SMS Center" in that page you will get the packet format.

if you trust me, then Logo manager is best option because there is lot of confusion makin FBUS Packet.
