Hi everyone,
My question is very simple but I couldn't find an example ,so I want to remotely control arduino through android app using cellular module like SIM800L ;More precisely an android application runs on smartphone sends commands to arduino bord and both (smartphone and arduino) are connected to the same mobile operator for example : turn on the light in the house when I'm out .
I have seen some examples using SMS to send command but I would like to use HTTP protocol because the cellular module supports TCP/IP connection .
I will be grateful if you help me implement this idea.
thanks.
