PM_RA_PROTECTION does not reject blacklisted connection

[lcalvez]

Hi,

I am working on nrf52840 and I am trying to enable the repeated pairing attempt protection. (PM_RA_PROTECTION)
After enabling the module I can see the logs telling me the device trying to pair is blacklisted and removed from blacklist after PM_RA_PROTECTION_MIN_WAIT_INTERVAL.

However, when I try to reconnect with the same device during the time it is blacklisted, the connection is not rejected.
I tried to find in the code where this rejection should be called and it seems the function ast_peer_blacklisted() is not called on connection.

Could someone help me understand how this features works so I can implement it to my project? There seems to be little documentation about it.

Best regards,

Hi,

What SDK version is this based on? I'm not aware of any known issues with this mechanism so I think I have to try and see if I can reproduce the same behaviour here.

Best regards,

Hi I am using SDK 16.0.

I am using the library quite differently because I am blacklisting devices manually by calling                 ast_auth_error_notify(m_conn_handle_peripheral);

My question is where should I look or what module should I enable to ensure the peer manager checks if the device is blacklisted on connection ?
