Use “hidden” mode for Bluetooth on your mobile device

When Bluetooth is enabled, make sure it is “hidden,” not “discoverable.” The hidden mode blocks other Bluetooth devices from recognizing your device. This does not prevent you from using your Bluetooth devices together. You can “pair” devices so that they can find each other even if they are in hidden mode. Though the devices will need to be in discoverable mode to originally locate each other, once they are “paired” they will always acknowledge each other without needing to rediscover the connection.
