AT commands for sending message and to the given recipient.....

[bilaljaved]

hi everybody!
I am doing a project which will take a mobile number from a keypad and save in the on-chip memory of micro-controller that is being initialized,my question is that which AT commands are to be used that send the message to the given recipient,your help will be very much useful for me in any sense.
Thank you.

ok,as i said that the user have to enter a number from keypad so every number will be unique and when a user enters his number it is saved in 11 digits memory,numbers are to be picked from here,what will u suggest about it e shade???

Hi bilaljaved,
Sorry, may i know in which type memory you have to save and retreive the information!!!

 

[ckshivaram]

you can store the number in the flash of controller or use external eeprom and implement using I2C protocol...

@ckshivaram: Hi Boss, do there any standard or rationale for the term "11 digit memory storage"

 

[ckshivaram]

No there is no standard if you store in controller flash... you can do it by storing in a array..

If you use external flash like eeprom then you should follow I2c Protocol standards.....

ok fine boss. let bilaljaved post his need.

@ckshivaram: Hi Boss, do there any standard or rationale for the term "11 digit memory storage"

no there is not but i have written a loop for it by moving some value in pointer register well can u people answer my question please !!!!

i really did not understand your question... if you have problem then post the code here so that someone will help you.......

Ok sir sure why not thats an good idea i will surely do it soon,thank you!

sir this is my another code that uses AT command to call,please check it and spot out my mistake thank you.....
i don't knw what is the problem in this dialing AT command???

how can you use " CALL: DB "ATD03139791313;",13,10,0 " instruction
in your program CALL is a keyword, did this program not give your error??????????????????

even if you replace the CALL: with any other variable name....

the ATD command is getting called infinetely , so how can modem execute a repeated command so fast...

so instead of sjmp start , use sjmp $ and try to execute the program...

it means that the syntax of AT command is right that i wrote???
no it did'nt gave any error,more over u told me that instead of sjmp starti should have written sjmp $,i have tried it but no results!!!
can there be a hardware problem sir????

 

[ckshivaram]

post your circuit.... connect board to pc and power on ... check what message comes on terminal.... does it read atdxxxxxxxx or not.... it confirms that controller and code are working.... then test modem with terminal and confirm its working for atd command...

then use the same cable to connect modem and controller and test it....

sir this is my circuit.i want to ask the following few things;
(1).i have only connected the TXD pin of controller and not RXD,as i am only making a call,does it makes any difference if i don't connect RXD of controller???
(2).also am using RJ-45 connector instead of RS-232 connector,does it make any difference???
(3).am using the buses of mobile that are behind the battery for transmissiondoes it leads to any unfunctionality???
THANK YOU............
