NRF5340 SoftDevice Controller reports different version than NRF5340 QDID matrix

[grifcjrkly]

Hello,

I noticed that the SoftDevice Controller for nrf5340 in nrf Connect SDK 3.1.0 reports a bluetooth version of 6.1 (LMP Version 0x0F), yet the QDID for it (Q360820) is listed as using Core Spec 6.0.

Do the versions need to match? 

Is it an issue for Bluetooth certification where a listing declares compatibility with a certain Core-Spec version, say 6.0 to match the version documented in Nordic's NRF5340 QDID matrix, yet the controller component declares it supports a later version via LL_VERSION_REQ/IND?

I must correct some more inaccuracies I made while assimilating the information for this question. Apologies, it has been a while since I've been in this part of the stack.

We are using BLE, so there is no LMP version, it's just the LL version. Wherever you see LMP version referenced, please replace with LL version. Below is the indication in question that contained 6.1 version identifier.



Also, there is no LL_VERSION_REQ, it is just the above indication which is used for central/peripheral version exchange.

The questions still stand regarding whether the 6.0 QDID Q360820 is still valid for the controller given it has updated the LL version.
