Hi,
I'm working on an application that implements both the Central and Peripheral role.
I would like to use the Just Works bonding (I have confifgured the Security Parameters as described in https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v11.0.0%2Flib_pm_usage.html ).
The problem is when my application (as Central) connects with an already bonded Peripheral witch has delated the Bonding information (or probably doesn't use the bonding).
In particular I receive the PM_EVT_CONN_SEC_FAILED event from the peer_manager module, please see the following log of a wrong connection.

I have handled the PM_EVT_CONN_SEC_CONFIG_REQ event but seem that it works only when my application connects with a Central device.
Is there a way to allow the a new pairing of an already bonded Peripheral?
Please help me...
