Changing OLED display through bluetooth with a mobile app

Hi guys,

I was wondering if it would be possible to change what is displayed on an OLED display with a mobile application via bluetooth. If it isn't possible, why?

Thanks a lot!

I don't see why not. If you've got a bluetooth module for Arduino, and they are available, you've got the communications part licked. Now do you know how to hook up the OLED display, read incoming Bluetooth, and writs whatever code will modify your display.

As jrdoner said, this is absolutely possible (I've done it myself).

If you don't have an app to send data yet, you can practice with input from the terminal.
