Can this direct link be accessed with Characteristic_UUID, with Service_UUID, or with a Mac address? Is there a sample code for the Arduino IDE? ...

How to create a bluetooth whitelist for esp32? Is this list created with mac address values of the devices allowed to connect?

Is there a code snippet?

For example, createWhiteList (macAdressValue).

I think it has to be supported in the BLE implementation on the ESP32. It’s optional. The ESP32 isn’t “found” because it isn’t advertising (transmitting) its services all the time. Its receiver is listening for a certain transmission, if heard then it starts advertising as a normal peripheral. It’s...

My aim is not to turn off bluetooth communication. For example, Macbook and magic mouse are not seen by any device. But the Bluetooth communication between them continues. I want to hide the communication between esp32 and the other device from others.
