my project started to be so complicate but I'll try to describe my problem in brief.
I'm planning to get some devices to work with a SIM800 GSM controller. My goal is to turn devices on or off and maybe with an alarm time.
Everything went ok until I needed to send an sms to the controller for setting the time and date so the device works. It was easy for me (as I'm not a programmer) to write a simple code so when the word ON is in the sms something turns on!
Can someone tell me please where to start or which methods in C++ I must take a look at?
And no people, it's not DO MY WORK FOR ME! I'm just a hobbyist and I have skills in electronic more than programming.
Any help is appropriated!
