QDID used during BLE authentication with third-party modules

Hello Hieu,

I understand that only RFPHY is assigned the QDID s132, while the others use the QDIDs of the SoftDevice Controller subsystem and Host subsystem.

Thank you.

Hi ReoN,

The Link Layer is a part of the Bluetooth LE Controller, not the RFPHY layer.

You do need to use the QDID of the default Bluetooth LE Controller in NCS, which is named "SoftDevice Controller".
You must not use the one for the S132 v5.0.0.

While the term "SoftDevice Controller" and "SoftDevice" sound similar, they refer to two different things.
A SoftDevice is a part of the nRF5 SDK solution. The component S132 or S140 are different SoftDevices with different capabilities and compatibilities with different SoCs.
A SoftDevice Controller is a part of the NCS solution. It is the Bluetooth LE Controller there.

Hello Hieu,

Are there no changes to the Link Layer in the upgrade from S132 v5.0.0 to nRF Connect SDK 2.6.1?

Is it acceptable to assign the same QDID as RF-PHY even if there are changes to the Link Layer?

Thank you.

Hi ReoN,

I can't access the QDID search now, so I cannot confirm that numbers are the correct one.

You can select the module's QDID number for RFPHY.

For the other parts, they are not all the same number. Notice that the LL part has to use the QDID number for the SoftDevice Controller, and the L2CAP and GATT parts have to use the QDID number for the nRF Connect SDK Host Subsystem.

Hello Hieu.

Just to confirm, as shown in the image, should I select 97989 for the RFPHY item and select 239299 for all other items?

Is it necessary to conduct additional tests?

Thank you.

Hello ReoN,

You can refer to the RF-PHY part from the BLE Module's QDID.

The application part is separated, so the fact that the BLE Module was qualified with S132 v5.0.0 doesn't affect the RF-PHY qualification.
