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 ?

you cannot relate AT command with FBUS.

even N73 accepts AT Command, its one way to communicate with modem not with phone. phone with modem accepts AT Commands.

FBUS is protocol designed by nokia. whereas AT Command is a standard followed by all GSM Modems.

Hi Again,

Thanks for your reply.

Can you please give me the list of F BUS and AT based mobiles. I mean how can I differentiate between AT and F BUS protocol based mobiles.

Secondly, I have another cell phone Nokia 1100. Can I interface it with 8051 for sending and receiving messages through TX and Rx pin of 1100 ?
As I know some basic AT commands and also worked on SIM300 modem. But I want to ask that in which format 1100 receives and send messages ?
And which data cable is there available in market for 1100. Is it phone to PC serial or to PC USB ??

Please reply soon.

Gaurav this is not right place to ask this question they should be in GSM Forum but i will still answer.

most of series 40 devices of Nokia uses fbus protocol. and this protocol varies from phone to phone so you cannot generalize it. for AT command list of phones, try a search in this website.

There is no information out there right now for Nokia 1100. try checking gnokii.org if they have done some research on communication protocol of this.

Nokia 1100 has serial interface cable.
