Receiving message to PIC through GSM modem

[andymuller]

Have you set new message notification? It is not in your code.

Hello Bird,

Yes, there is a pin on sim900 GSM modem, if a new message be received this pin will be in high state less than 1 second, I use this pin for the new message notification. But i didn't use this feature in this sample routine. Because I am still busy with comparing two things with each other... the question of this thread is still valid

Thank you

Is this the code that does the comparison?

if (s(59)="S") then
 high portc.3
 s(59)=0
 endif
 if(s(59)="T" and s(60)="a") then
 low portc.3
 s(59)=0
 s(60)=0
 endif

and needs modifying to "LED1ON" and "LED1OFF" but does not work even with the simple test of "S" and "Ta"?

Hello Steve,

Thanks a lot for your posting here.

I apologize. I was late in reply

Yes, it is, it compares incoming message with a pattern and chooses what commands must run. here is just simple put a pin on high or low states.

Do you have any other suggestion for comparing?

Thank you
