Hi, Can you confirm that is sufficient change the flag .allow_reparing = true, to allow the bonding with already bondend device?

Hi, with peer manage it is enough to change this command line:

  case PM_EVT_CONN_SEC_CONFIG_REQ:
     {
     // Reject pairing request from an already bonded peer.
     pm_conn_sec_config_t conn_sec_config = {.allow_repairing = false};
     pm_conn_sec_config_reply(p_evt->conn_handle, &conn_sec_config);
     }
     break;//PM_EVT_CONN_SEC_CONFIG_REQ

setting the allow.reparing in true.Correct? But i'm very curious about this situation. I expect that if i delete the bonding information the peer manager don't remember that thsi device was bonded in the past.

is there a tutorial that can be descrive this situation?

Thanks, Anna

Thank you. I now know that IRK is unique per device.

New encryption keys will be exchanged when doing a bond refresh, but the IRK/Address of the central will remain the same. Device manager checks for address or IRK match to determine if it has bond info for a connected peer device.

How can device manager know change of bondong information?

I think iphone's pairing information will be changed when I delete bonding information in the iphone, So device manager(pca10028) will not be able to recognize as already bonded device.

The device manager in SDK 11 rejects new pairing requests from peer centrals that are already bonded to impeded the bonding information from being updated by an attacker. You can diff the device manager in SDK 11 with the one in SDK 10 if you want to revert this change.
