I need a suggestion on which bluetooth device would be the best for this project.
Parameters- I need to have one bluetooth connected to an Arduino, it will need to detect any one of approximately (15) BT devices when they come within range, but does not need to connect to them only turn on a different LED based on which device is detected. I think this can be accomplished by creating a predefined whitelist of MAC addresses of the (15) devices. Any suggestions would be appreciated.
