Unencrypted PDU’s allowed during secure connection pairing after LL_ENC_REQ from master.

ID: DA1469xSDK-4038

Status: Open

First reported: 10.0.12

Fixed in: TBD

Description

When in Secure Connection Pairing , the controller of the DA1469x (Peripheral) , allows reception of unencrypted SM PDUs from master after LL_ENC_REQ until the secure connection is complete. The unencrypted PDU’s will never be handled by the application and therefore are not a security issue. When in Legacy pairing, controller correctly abandons the connection with a MIC error when this happens.

Workaround

At this moment there is no workaround available.
