How can I connect directly to a bluetooth device without advertising?

For example, how do we connect directly to an android phone or another esp32 device?

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?

For example; connect-> connectmacadress (xxxxxx)

To be honest, i've been sure it is possible to connect to peer device with mac address without scanning even if device is not advertising, but i did some tests and seems it is not possible (at least with this library).

Only we can do is to ask mr Angus to ask espressif devs that are bluetooth experts what is the correct answer on this question.

Hi Chegewara,

Did you have any answer for this?
