wait for a string

[aratti]

This snippet should solve your problem.

EEprom 0,[49,55,49,55,49,48,57,53,57]  '  your number without the area code 1717101959

InBox    var Byte  [8] ' make your array larger so you can use a byte as command
Num0    var Byte  [9]
Num1    var Byte  [9]
Flag      var byte
Try        var Byte
A0        var Byte

For A0=0 to 9
Read A0,Num0[A0] ' here you load you number in array Num0
Next A0


IniCall:
Try=Try+1
If Try>5 then delet_sms ' if counter >5 then abort ( if 5 cycles are too many reduce them to an acceptable number)
SerOut2 txd,Baud,["at+cmgr=5",13]
SerIn2 rxd,Baud,1000,IniCall,[wait ("+880"),Str Num1\9,skip 32,str inbox\8] ' here you load the incoming number into array Num1

Try=0
Flag=1
For A0=0 to 9
If Num0[A0]<>Num1[A0] then Flag=0 ' here you compare the two array if not all digits agree then Flag is set to zero
next A0

If flag=0 then delet_sms ' flag reports "not corrected number" so delete sms


'your code here to work with the array  inbox

goto mainLoop ' your code mainLoop

delet_sms:
Try=0

' your code for deleting sms


'If you make an  inbox array equal to 11 elements then you can use it to change the number when needed
For instance if inbox[10]= 100 then gosub Change 


Change:

For A0 =0 to 9
Write A0, inbox[A0]
Num0[A0]=inbox[A0]
Next A0
Return

Your number is stored into the eeprom and is loaded in the array Num0 at runtime. I am not sure if "880" is the area code.

If Try>5 then there is not sms, so you don't need to delete it. Trying to delete is dangerous because you could delete an incoming sms.

My question still is what if you have deleted all SMS and the new valid arrives at location 1?

sms index 1,2,3,4 are used to store the emergency sms. These sms are used to notify the user .

Hi aratti . Thanks for your help. I have solved it.
Can you please inform me one more thing, When any new sms arrived, the GSM modem send a notification " +CMTI: "SM",5 " .

How i can use this notification to interrupt in my program.

[Ioannis]

Your program might be interrupted only by an Hardware Interrupt, say from the USART module.

So, if you want a fast interrupt system, have a look at Darrels Instant Interrupt.

Then every time you have an RS-232 activity, the ISR will take care of the event. Store the incoming data in an array and do a compare byte-to-byte with a stored reference array, say in the EEPROM.

I am working on a similar project and may post a snipet as soon as I get it working.

The best way is the one that Ioannis suggested you in post #9.

For "HSERIN" instruction you have to use specific pins of your pic micro (you didn't say the type), which are the USART module, plus the DT interrupt routine.

Serch the forum for DT interrupt to learn more or go to this link: http://www.picbasic.co.uk/forum/showthread.php?t=3251


XXXXX you can download the project for sms controller at this link:http://techni.caliti.es/blog/2008/12...ontroller.html

since the project is well documented, you could see the technique used to activate 8 relays or read the status of 8 inputs all via sms command.
