CONFIG_BT_ID_MAX = 2

[John]

For nrf Connect SDK, can I config CONFIG_BT_ID_MAX = 2, both adress type are Public for below use case?

ID with index = 0 for peripheral role and  for connect and bonded with sartphone.

ID with index =1 for centrol role and for connect and bonding with other ble peripheral.

Because whenever unpaired with Smartphone, we need to change ID with index  = 0 to other ble address.

But, for ID with index = 1, we not going to change it unless doing factory reset, so that it won't affect the reconnection for the bonded peripheral devices.

The scenario described above does not require 2 BT IDs. I'm running a device with both central and peripherial roles on a single ID successfully.

The ID rotation stuff is not required when you allow a pairing to be overwritten somehow. Can be configured via prj.conf file but should have additional application code ("pairing mode").
