Most tutorials teach you have to control an Arduino using the app they create. I would like to do the opposite. I would like to control the app with the Arduino using Bluetooth. When an alarm is triggered on the Arduino, Id like it to send a signal to the app and have the app send a text message. Does anyone know how a beginner could achieve this?
I don't know if this is exactly what you need, but here is a youtube video I found that might be helpful.

Hi.
You can do this up to a point. The app can recognise the text received via BT and send whatever text message you have programmed it to do.
However, it will call on the phone message handler service which will require the phone user to press the SEND button. So it will not be fully automatic.
That is my understanding -- can anyone else confirm?

I see. That does pose to be a problem. I wonder if there is anyway I can get around this.
