Topic: Bluetooth Icon on Oled Display When Bluetooth is connected (Read 213 times) previous topic - next topic


Hi there,

In my project I have an Oled display and a Bluetooth HC06 device. Got it all working, connect my Android phone and control the project from the phone.  :smiley-cool:

Now the question: how/when can I display a blue "B" to the oled display, indicating that there is a connection.

I mean: when I turn on the phone, and make the connection from the phone (using Ardudroid) to the HC06, is it possible in the code to say "Ok, you have a BT connection now, send the BT icon to the display".

Can I read it somehow from Serial.Available ?

Thanks for your help!
