Please bear with me, I’m a NOOB concerning the Arduino, but eager to learn
What I like to accomplish is a Bluetooth ‘beacon’ that send out a message.
People should be able to receive the massage by phone without paring.
Kind of local advertising to mobile phones with Bluetooth on.
I’m looking to use HC-05 and a attiny chip to make it stand alone without the arduino board.
Has this been done before or is there someone who can tell me how to create this?
