please help me get info about this report

first you have to choose what brand of mobile phone you are focus and go to the manufature website to get the information you need.
but base on my experience most mobile phone have the same AT commands.
you could also search on this website someone post the at command there for siemens phone

i need information about AT commands in common
thanks

Here is a list of the Nokia AT command, and do not believe that all mobile phone have the same AT commands if they cannot provide you with data.

Btw, this requires a DL3P cable and a Nokia Phone with built-in Modem, this is for a Nokia phone.

Other registers are set to zero.
This only resets the virtual modem and not the phone.

i suggests you get the datasheet for more detail and there might be some changes

Just initialize the RS232 and learn how to send ASCII characters via serial.

are these the only AT commands for mobile ?

I think there are other AT commands for Nokia mobile aside from what is listed in GNOKII website, you can search for the said commands on the net.

thanks glenjoy
but please tell me because im not professional like u , whats the RS232 and ASCII characters ? and please give me the GNOKII website
thanks again

Rs232 is a communication standard, you can use a PIC micro UART to communicate in RS232.

For ASCII characters, you can search google.com for a good explaination.

Search google gor the GNOKII website.

Thanks is not allowed here in elektroda but rather press the thank you button for posts that helped you.

Who said so? A thank you is alsways welcom. The new people do not know how to use this web site. The more time they well spent here, the better they will know.

Second, nofnof:
AT Commands as you already know are commands that are supported by most modem. A mobile phone is also a modem ( well most of them that support this feture ). You can find the appropreate AT command for the modem that you are using by searching google this way: "AT Command" nokia. This will give you the nokia AT command set. The brakets ( " ) must be used so google will know to search the complete sentance.
Regarding the PIC. Here on this board you can do a serach. there are a lot of postes talking about the RS-232 output of a PIC using ASM or C. For more information you can go to one of the web sites on the net like:
www.microchip.com - go to app notes, and then go to RS232 or USART.
www.microchipc.com
Or any of the other sites that have C compilers for the microchip parts.
After you will know how to send and receive the AT command from the PIC and what each command will do to the modem, its all up to you now what you want to do.
If you will have any questions, post them with as many detailes as you can. The better your question, the beter is our answer.
Good luck.

To get the standard AT command docuemnt you need the ETSI or 3GPP for TS0707 pdf, there are all inside the docuemnt for general mobile AT command.

www.etsi.org

Generally speaking, the AT command has similar to what we used on modem, however, its depends on the function of the modem. For example, A voice modem should have AT+FCLASS=8, voice mode, but not for mobile phone.

And some of the mobile has CKPD command(KEYPAD), but not for a 56K modem.

In case you cant find it, here is the document
