About QDID For Sig Ceritifaction

[BEN_HBC]

Hi. 

I am attempting to obtain SIG certification.

I am using ncs v3.1.1 with nRF52833.

Based on the link below,

https://docs.nordicsemi.com/bundle/comp_matrix_nrf52833/page/COMP/nrf52833/nrf52833_ble_qdid_qual_matrix.html

I submitted the application through a certification agency with Q370938 as the Host and Q360830 as the Controller.

However, I am encountering a problem because the Controller DN Q360830 does not support channel sounding, while the Host DN Q370938 does.

As far as I know, the 52833 does not support channel sounding;

And they said that the controller supports 1M, 2M, and Coded, but since I stated that my product only uses 1M, they say that a QDID valid only for 1M is required.

In addition, it is said that the Host requires a QDID that does not support channel sounding, etc.

in this case, what should I use as the QDID?

Issue is ILD Issue.

Hi

As far as I know, it's not a requirement to support the specific PHYs and Channel sounding is an optional feature. You are correct that the nRF52833 doesn't support Channel Sounding (or Coded PHY for that matter). 

Who exactly are claiming that the QDIDs need to be for specific PHYs and feature sets? I can run this by one of our certification experts to confirm as well, but it looks like you have the correct QDIDs for certification here.

Best regards,

Simon

EDIT: The Host QDID has specifically not support for Channel Sounding here. It is a subset of Q370860³ which does support Channel Sounding.

I received this from the representative at the agency entrusted with the SIG certification. According to you, are you saying that the Q370938 does not support channel sounding and that specific PHYs are not mandatory? It is late today, so I will speak with the certification manager again tomorrow.

If you do not mind, could you please ask the certification expert to verify the above information one more time?

Hi

I had a chat with one of the certification experts in-house today, and he confirmed my suspicions. The requirement for a QDID to the specific PHY used is not correct. You can claim 2Mbps capability on your device without using it in the application for example, so that should not be an issue.

The QDID DNs you submitted are correct for the nRF52833, with Q370938 as the Host and Q360830 as the Controller. Q370938 was specifically made to remove the Channel Sounding ICS item. They can look in the GAP table 25a where no Channel sounding features are selected for example. 

The nRF52833 (as you said initially) doesn't support Channel Sounding, so getting a QDID for that wouldn't be possible in the first place. Please ask your agency to double check the QDIDs you provided, or get a second opinion.

Best regards,

Simon

I forwarded the answer to the question posted here to the certification agency. However, the agency replied that certification is possible using the combination of 239354 + Q360830. In this case, would there be any issues if I proceed with that certification?

Hi

239354 will not be the correct QDID to use for an application running NCS 3.x.x, as it is the QDID for NCS 2.6.0 to 2.7.0. Did they say why Q370938 was problematic? It is not qualified for Channel Sounding. As I mentioned, checking various GAP tables etc. should confirm that no Channel Sounding features are selected in this QDID.

Best regards,

Simon
