Pic to GSM Phone connection (HSerin problems)

[Ioannis]

On the following code the phone responds ..."REC READ",... if the message was read sometime before. If you have a fresh new message then this becomes UNREAD as you state on your code.

So, why don't you change your code to:

HSerin 5000,loop,[wait("READ"),... since the word READ is present all the time?

' +CMGR: "REC READ","+xx1234567890",,"05/05/26,17:19:23+00" GOOD
' Loop could be setup as a routine such as:
' Loop:
' List new Messages again - as above (think about it)
' HSerout ["AT+CMGL",13,10]

HSerin 5000,loop,[wait("UNREAD"),skip 3,STR Caller\13,skip 4,STR GSMTime\17,skip 6, STR GSMBUFFER\16\13]

Thank you for the info.

I was wondering if you could tell me how I should use the data that is captured within the GSMBuffer i.e. the SMS text as I would like use this to switch on an LED. Should it be something like this:

IF GSMBuffer = Switch on then LED = 1

Thanks in advance.

Kind Regards,

PBP does not have such string compring capabilities.

You have to make your own subroutine to compare byte to byte the two string array. Like that:

i=0
while i less_than gsmbuffer_length (I cant sen the less character! Why?)

if gsmbuffer[i]=compare_array[i] then
'gsmbuffer[i]=0
i=i+1
else
goto wrong_sms
endif
wend
correct_sms:
'your code here

wrong_sms:
'your code here

You understand that in compare_array you have to put your characters in some other place of the program prior to the above subroutine.

Thanks again but I'm afraid I dont quite understand. Really sorry but would it be possible to be little clearer.

Thanks again.

Hmm, what part you are not understanding?

Sorry.... would it be possible to add comments to each of the following lines:

if gsmbuffer[i]=compare_array[i] then
'gsmbuffer[i]=0
i=i+1
else
goto wrong_sms
endif
wend
correct_sms:
'your code here

wrong_sms:
'your code here

Could you give me an example using the SMS keyword: "switch on" in order to switch on an LED.

Thanks again.

The commands used in the small piece of code are very elementary. So you have to read the manual because all the answers are in there.

I cannot explain how an If-Then-EndIf statement is syntaxed or how is working. The code I gave you is very very easy and basic I could say.

It is comparing one element of the array gsmbuffer at a time with one element of the other array. If it succeeds then it is moving on to the part of the program labeled:

correct_sms:
'you add your code here

If it does not succeed then it is moving on to the part of the program labeled:

wrong_sms:
'you add your code here

Try to write some code and see what happens. One part at a time...
