ESP32 Forum

Hello,

I am working on a BLE device ( ESP32 ) with a pairing process, which allows only previously bonded device to connect back using C++ BLE library. For that, i use whitelisting to memorize the address, and only advertise to these addresses. The problem i have, is that the address of Android and iOs are randomly generated, and changes, so the device cannot advertise to previously address.

How can my ESP32 memorize these random addresses, using whitelist, to run properly ?

Thank you

why can't you whitelist a custom UUID?

I didn't know it was possible ? How can i do that ?

You can see the UUID on scanning, just like you can see the mac.

Yes, but i want to filter my advertising from the server side, and not my scanning.

you can not filter on advertisement, since it is a broadcast.

Anh-Minh, did you ever resolve this issue? Looks like there's a bug/limitation in ESP32 that doesn't allow whitelisting resolvable random addresses used by most modern smartphones.
