About whitelist storage area and data

[sdi_kei]

Hello.

I am developing using nrf52832 (S132 v7.0.1, SDK v16.0.0) as a central and Android device (Bluetooth 4.2) as an advertisement.

During development, I was wondering about the whitelist storage area.

1. When bonding with an Android device, it seems that the data will be written to the Whitelist via the peer manager. Is it possible to specify the area to be written?
2. Is the only data written to the whitelist the address and IRK? If other data is written, is there a setting?

I would like to know if there are any materials written about each.

Please let us know if you have any questions.

Thank you.

thank you for your answer.
Sorry for the late reply.

It was 76 bytes instead of 72 bytes, excluding the 8-byte header of the flash page and the 12-byte header of each data.

It was confirmed that the first 18 bytes of the 76 bytes contained the IRK, followed by the 6-byte MAC address.
It was followed by 28 bytes of unknown data, with a 12-byte header and a 4-byte peer rank.

I still don't know about 28 bytes of data.

We will continue to investigate.

Thank you.
