HC-05 + Attiny Bluetooth ‘beacon’ t send message

Development Boards Arduino
1

Please bear with me, I’m a NOOB concerning the Arduino, but eager to learn :smiley:

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?

Have a look at this thread:

and use Google to look for “bluetooth broadcast without pairing”
