Hello everyone,
I'm trying to build an application that will simply trigger relays using sms on GSM module.
What I have done so far (basically)..
1. Get GSM signal and manufacturer
2. Send sms
Now I'm trying to read incoming messages but with interrupt (with DT's). but it seems that when I send a message to the GSM the following block of code does not function
The following code is what I'm testing...I strip out the other codes within the main loop just to simply...
I think the GetBytes sub program triggers on boot up because it displays Hserout ["Went here",13]...after that when it enters to the main loop and try to send sms to the device it never get the interrupt.
Can anyone spot what I'm missing? I've been going nuts with it the whole week :frown:
Regards,
tacbanon

Code:
Getbytes:

cntr = 0
While RCIF = 1 ' clear the buffer
HSERIN 50,error,[Wait("P")] ' test it
Hserout ["Got it!!",13]
