role of at commands in mobiles
>Nokia 3100 mobile phone..is it a good choice??
Yes, as many other phones: If You already have a Nokia 3100, then use it.
>does Nokia 3100 accept At commands?? and is it easy for it to deal with the >microcontroller??? if not..can you please suggest other mobile phones !!!
Yes, it supports AT command
>the other thing is...the AT command itself...is the code written in the PIC the >same code written in hyperterminal?? (maybe stupid question..but i really know >nothing about all of this Crying or Very sad)
Yes, they are the same
>the third thing is...should there be a program on the mobile phone to accept the >AT commands??
Of course, I think it's a embedded function of the firmware
>...how do I know that the mobile received the data from the PIC..or that needs >another program in j2me for example...or that can be told without having to >make any prgramming (I already made some programming but that was for gprs >to send data from the mobile )
AT request sent by PIC will be confirmed by a message 'OK' or 'ERROR' or
a numeric code, so You will have to parte the answer .
Have a look to AT command help document at Forum Nokia site for appropriate AT-commands.
A tip:
Because not all AT commands are implemented in all phones, You can test wich
AT commandds are supported sending the command string:
AT+CMGS=?<CR>
You can experiment first using a terminal program on a PC. and then You
will be able to code the AT commands in the PIC.
