Effect on BT qualification if applying Nordic suggested workaround

[spanceac]

Hi,

We're developing BLE products with the software developed on nRF SDK v3.2.2.

We are affected by the known issue of the SDK: NCSDK-32763: Upgrading firmware may corrupt Bluetooth bonding keys.

Nordic's suggested workaround for this issue is to apply this patch on top of the SDK.

We want to leverage the fact that the SDK releases are BLE pre-qualified, as the documentation here states: "If your product uses a qualified Bluetooth stack provided as part of the nRF Connect SDK, you can inherit this qualification from Nordic Semiconductor, provided that you do not introduce any changes to the stack".

The question is if applying this patch suggested as workaround on top of the SDK affects the BLE qualification of the SDK?

Hi,

The use of the QDID is still valid. You can continue using the qualification with the patch.

Hi,

Can you please argument shortly on why applying that patch is not a problem for invalidating the QDID? I'm asking because it's a patch applied over the BLE host subsystem.

Thank you!

The changes in the patch has been evaluated to not impact the Bluetooth qualification as part of the development of the patch itself.
