i can make it send sms with a push on a button...
Hi
I'm trying to build a GSM remote control for my car preheater....
What i want is to turn on the unit with a sms, but subsequent i will also want to send some status sms back.
of course i could just send the status text back to a list of numbers.
but ideal i want to send the status to the phone that started the unit.
for most uses we will only be 2 phones controlling the unit but it might change later
what i had in mind is that the sketch runs a loop where it checks for an incoming text
if there is one grap the number and then if the text says start do "blablabla" and delete the text
for starters i will just turn on a LED
now if i try to turn it off from the other phone it should just send back a text saying i did not turn it on and then delete the text
in the same loop i will pull stats from the heater and when thing happens i will send the stats to the phone that turned on the unit... hence my idea of grapping the number of the phone that starts the unit
any ideas?
