What do you mean by independent whitelist? Are you setting the whitelist manually? If you are, then you need an independent whitelist.

E.g. if collector wants device2 in its whitelist it will need the irk and address of device2.

Similarly, if device2 wants device1 in its whitelist it will need the irk and address of device1.

What example are you using? In the SDK, a device will be added to the whitelist after bonding, and you don't have to think about the address or irk since the Peer Manager has taken care of this and stored it into flash.

Hi Simon,

Thank you very much for your link, indeed, it has been very helpful. So i guess whitelist are the solution for what i want to implement. One more question

Here is what i want :

Link 1 between Device 1 and 2 cannot change.

But, on device 2 side, can i use independant whitelist for (1) and for (2) ? or do i need to use the same whitelist for the two links.

Regards,

Aurélien

I have elaborated earlier on the difference between scan filtering and whitelisting. Check out this answer.
