Describe the solution you'd like

Home Assistant has BLE-based presence detection, in order to connect my phone and smartwatch, I need the BLE Identity Resolving Key (IRK). I was able to obtain the one from my phone using https://github.com/fryefryefrye/Decoding-Random-Bluetooth-Address/tree/master/esp32_get_irk/Arduino/esp32_get_irk , but that solution requires a device to connect to the ESP32's bluetooth, my smartwatch can't do that, it needs to be connected to.

So what I need is a way to have https://github.com/espressif/arduino-esp32/tree/master/libraries/BLE/examples/Client to show the IRK like the other mentioned sketch does, only this while the ESP32 acts as a client instead of a server.

Describe alternatives you've considered

On https://www.home-assistant.io/integrations/private_ble_device there are various ways mentioned, so far unsuccessful:

• the Android adb-method: No IRK of my smartwatch in the capture
• the Windows-registry method: No IRK on various systems, various Windows versions and 6 different BT-controllers. Also checked out Ubuntu, found some info about the connection, the IRK wasn't part of that info
• the earlier mentioned ESP32-method, which requires the device you want the IRK of to connect to the ESP32, the smartwatch can only be connected to.

Additional context

The IRK is required for Home Assistant in order to do presence detection with certain BLE-devices that randomly change their bluetooth-address, see https://www.home-assistant.io/integrations/private_ble_device for more info.
