This is a rather simple project; the main difficulty was in getting the Telit module to play nice

It took me a while to realise that any serial data sent to the module was being echoed back; this is because I *assumed* that I had enabled this option in my terminal utility (a good one for Windows is SecureCRT; Zterm for Mac).



Here's a snippet from the comms log, at least for sending a SMS...

Code:
michaeldesilva@macbook-pro:~/Desktop/code_py$ python gm862_sms_and_calling.py

Initialise:
> ATE
['OK']
> AT&K0
['OK']
> AT+CMGF=1
['OK']
> AT+FCLASS=8
['OK']
> AT+CNMI=2,2,0,0,0
['OK']

Diagnostics:
> AT
['OK']
> AT+COPS
['+COPS:', '0,0,"SRI', 'DIALOG"', 'OK']

SMS:
> Send SMS: "If my calculations are correct, when this baby hits eighty-eight miles per hour, you're gonna see some serious sh**."
['+CMGS:', '196', 'OK']
More ramblings on this topic may be found in the full posting on my blog.

Next step is to move this to a microcontroller. All this while I've worked with PICs and FPGAs from Altera. Planning to give AVR ago as I like the idea of not having to be tied to a commercial compiler; at least for hobbyist projects this is *not* a problem.

The motor setup of our automatic gate died a couple months back. This will allow for SMS controlled gate opening action, once I get around to dismantling the dead commercial product and installing my own version...with bells attached
