Hey all,
So I'm new to arduino and kind of taught myself for the most part over the past weekend. I've developed a code that allows me to control two output pins on my Arduino UNO R3 attached to my Adafruit FONA GSM 800H Shield via text messages, and the program works perfectly.
The content of each text received is stored in the replybuffer and then using a strcasecmp performs one of 3 actions.
I wanted to know if anyone knows of a verification sketch that I can use that only allows texts from a particular number to activate the void loop?
I want to be sure for security reasons that only texts from my phone number would be able to control the device and that any other number texting the shield would be ignored and their SMS deleted.
Please let me know if anyone can help with that, or point me in the right direction.
