Topic: Sending a message from Arduino to Android via Bluetooth module hc-05 (Read 2259 times) previous topic - next topic


Hello all,

I am working on a project in which I am hoping to create a button that when pressed sends a pop up notification on an app via Bluetooth (which I am hoping to create with MIT app inventor)

I have a bluetooth module hc-05 and an Arduino Nano. I am just starting and I don't have a clue how to begin, please help!


Welcome to the forum. For Arduino, you might find the following background notes useful


Bluetooth is simpler than it first appears to be.


I have created an app in MIT App Inventor 2 with some sliders to control an RGB led connected to an Arduino..

so kind of the opposite direction...

but I also do send initial text/message to the phone.

I can try to dig it up if you still need direction.  (although there are MANY MIT App Inventor Bluetooth tutorials out there already!!)

Let us know.
