nokia 1100

well.. the reason i told you to do ATI3 was to get the modem info.

coz most probably.. or maybe by mistake you connected to internal modem of your PC/Laptop

you can check this again by connecting to other COM port shown in your hyperterminal. you will get your answers..

as Phil said, Nokia 1100 works on FBUS protocol it does not have an internal modem.

hi ajay..!

i didnt know dat nokia 1100 does not support AT commands..
no probs if nokia 1100 does not support AT commands..
AT commands is not my concern,i just want to interface my phone wid microcontroller..
i donno bot fbus protocol n how to use it wid nokia 1100..

pls guide me on dis.. :-)

There have been many threads on F-BUS,
some say they got it working
but I don't think anyone posted actual working code.

Have a good look through the GSM forums.

i've gone through GSM forum,but did not find complete f-bus code in 'C' for nokia1100..
could u pls send me d link :-)

but I don't think anyone posted actual working code.

Our standard advice is to use a older model phone that supports AT commands.

Hello,

Actually I have N73 and I want to know that It is F-BUS based or AT command based?
Please Someone give me the list of F- BUS and AT commands based mobile.

And tell me what is difference between F BUS and AT commands. Is AT commands is older technology or what ?

Hi

I cannot find anyone who has communicated (with proof) with a nokia 1100/120X

I hooked up a nokia 1200 to the serial port and using mobius phone explorer to connect to it from my notebook and the following is happening:

TX:

55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55

RX:1E

TX:
1E 00 10 D1 00 07 00 01 00 03 00 01 60 00 6E D5

RX:
1E 10 00 7F 00 02 D1 00 CF 6D 1E 10 00 D2 00 24 01 00 00 03 56 20 33 2E 37 32 0A 31 34 2D 30 39 2D 30 37 0A 52 48 2D 39 39 0A 28 63 29 20 4E 4D 50 00 01 46 01 F5

TX:
1E 00 10 7F 00 02 D2 06 DC 7B

TX:
1E 00 10 1B 00 07 00 01 00 00 41 01 41 00 0E 1C

Then after some serious communication which I think is mobius downloading the sim phone book a ping pong game starts:

TX:
1E 00 10 DA 00 06 00 01 00 00 01 40 0F 9D

RX:
1E 10 00 7F 00 02 DA 00 C4 6D

TX:
1E 00 10 DA 00 06 00 01 00 00 01 41 0F 9C

RX:
1E 10 00 7F 00 02 DA 01 C4 6C

The only thing which is obvious to me so far is that 1E is the common first character of all frames.

The first character is the destination address and the second character is the source address.

The rest starts to look a little different from the other FBUS information I've found on the internet.

The ping pong thing is the same data over and over except for 3rd last character changing from 40 through 47 which also has an effect on the last character convincing me that the last character is some or the other checksum of sort.

The responding frame also follows the same pattern as its obviously ACK'ing the change in frames which are being sent to the phone.

Things get even more complex when a SMS is sent and looks very different to what can be found on the internet for nokia 3310's and I'm guessing that the protocol has been extended with additional pieces of data which currently appears to be undocumented.

Any takers?

Hola mi nombre Carlos yo hice un proyecto con un pic 16F84A a 4 Mhz con tramas fbus para llamar y cortar con el nokia 1100 pueden ver el proyecto en mi pagina www.carlosvolt.com.ar en la sección proyectos saludos

hi... no one really will post actual code for FBUS protocol..

but get over thoroughly to gsm forums and understand the frame.


you can do it in C... Delphi pascal oop.. even C# or VB.
all you need is the right handle to createfile... writefile to send command readfile to read the response.

you can find this handle tru register and get your device correct GUID.



hints:
1st byte
1E is Fbus
1B is USB


2nd and 3rd byte
destination and source address
followed by message length and
you need the correct sequence.. and last 2bytes would be the checksum of your frame
