ZSDK BLE host qualification references seems obsolete The BLE host qualification references in nxp-zsdk release notes refers to a very old qualification. E.g. nxp-zsdk 4.4 states; BLE Host, DN#: Q305748, Link *: Host qualification BLE Controller, DN#: Q380314, Link *: Controller qualification *: Requires BLE SIG account. This host qualification specifies BLE 5.4 support. The controller specifies BLE 6.1 support. To support all the features of the controller, the host would need the same BLE level or higher. So I think that the reference in the release notes are wrong, can you provide the correct references? Regards Tonny Re: ZSDK BLE host qualification references seems obsolete Hi, @tobg
Thanks for your reply.
I checked the tag you mentioned NXP Zephyr project v4.4.0 is release on May 11 2026.
And we have another newer NXP Bluetooth Low Energy Host Stack Zephyr DN: Q393055 is gotten on 2026-7-30. It means, we did not list the wrong BLE host QDID in the release note:nxp-zsdk/doc/wireless/release-notes/topics/rw610rw612_release_notes.md at nxp-v4.4-branch · nxp-zephyr/nxp-zsdk · GitHub.
It actually should be the old QDID number: DN#: Q305748.
But I want to correct your understandings, Host and Controller does not need to have matched Bluetooth Core Spec version. The Host and Controller are qualified as separate Bluetooth subsystems, and a Host qualified against Core 5.4 can be used with a Controller qualified against Core 6.1.
Please let me know whether still have any other concerns on this thread.
Otherwise, please do not hesitate to mark my answer as a solution for this case, Thanks!

Christine. Re: ZSDK BLE host qualification references seems obsolete Hi Christine, Thank you for your reply. I have a follow-up question about the Bluetooth host qualification. The release note links to https://qualification.bluetooth.com/ListingDetails/227830, which shows: Bluetooth Host Solution Zephyr, 2024-09-16 (www.nxp.com) Core Specification: Host 5.4, Active This is a two-year-old host qualification at BLE 5.4, while the controller is qualified for BLE 6.1. If we qualify our product against these listings, we can’t claim anything higher than BLE 5.4. You mentioned a newer host qualification for BLE 6.3, but the release note doesn’t reference it. That raises two questions: With a controller qualified for 6.1 and a host qualified for 6.3, which BLE version can we claim for our product? Could the release notes refer to the Zephyr Project / Linux Foundation host qualification instead (for example https://qualification.bluetooth.com/ListingDetails/332380)? Including a host reference only helps us if we can use it in our own qualification. Thank you in advance. Best regards, Tonny Re: ZSDK BLE host qualification references seems obsolete Its NXP RW612. Thanks Tonny Re: ZSDK BLE host qualification references seems obsolete Hi, @tobg
Can you please let me know which BLE product are you using?
I checked in the link you provided, it is RW610 and RW612, so I prefer to confirm with you that you are using RW610 or RW612?
So that I can check for you.
BR,
Christine.
Re: ZSDK BLE host qualification references seems obsolete Hi Christine, The BLE host we use with the NXP RW612 is the one in the Zephyr project, delivered as source code. It is not NXP software. Zephyr has a new release every 6 months or so, and the BLE host usually changes with each release. If we may only use BLE hosts that NXP has qualified, we are tied to one Zephyr version. The release notes refer to a version that is now more than two years old (probably Zephyr 3.7.0). Every release since then, up to the current 4.5.0, has included many security and functional bug fixes. Since 3.7.0, the Zephyr project has published 61 Bluetooth security advisories, 43 of them for BLE. If we are to rely only on NXP’s qualification, NXP would need to qualify the host for each Zephyr release. Could you send us an overview of which QDID to use for each Zephyr release? Nordic publishes a matrix like this, for example: https://docs.nordicsemi.com/r/bundle/comp_matrix_nrf52840/page/comp/nrf52840/nrf52840_ble_qdid_qual_matrix.html?section=nrf52840_ble_qdid_qual_matrix__sd-fn (In Nordic’s matrix, their SDK version numbers are different from the Zephyr version numbers.) Best regards, Tonny Re: ZSDK BLE host qualification references seems obsolete Hi Christine It is nice that NXP has an updated BLE qualification for 4.4.0, even though the release notes don’t mention it. If so, the Zephyr BLE host changed between Zephyr 3.7 and 4.4.0 but wasn’t qualified in nxp-zsdk for any of the releases in between. What are your plans from 4.5.0 onward? We need each nxp-zsdk release to include a qualified BLE host whenever the host has changed. Regards Tonny Re: ZSDK BLE host qualification references seems obsolete Hi, @tobg
I checked all of the branches in this link, nxp-zsdk/doc/wireless/release-notes/topics/rw610rw612_release_notes.md at nxp-v4.4-branch · nxp-zephyr/nxp-zsdk · GitHub
we already listed the QDID in each Release note. Even it is the same QDID, it means all of them are based on our NXP's same certification.
We only have 2 Zephyr based QDID, one is in 2024, another is in 2026.
And after this new QDID in 2026, there is still no other new release on our github:
nxp-zsdk/doc/wireless/release-notes/topics/rw610rw612_release_notes.md at nxp-v4.4-branch · nxp-zephyr/nxp-zsdk · GitHub
So I think in the future nxp-zephyr release, we might modify the release note to refer to the new QDID.
If you have any other concerns, please let me know.

With a controller qualified for 6.1 and a host qualified for 6.3, which BLE version can we claim for our product?
==>[Christine]:Yes, you are right. I think your product can only be claimed for 6.1 as the lower version. But need to point out that when you apply for the certification for your product, the Bluetooth Sig will also check the details of host and Controller's ICS and what kind of profiles you input in the application form.
Could the release notes refer to the Zephyr Project / Linux Foundation host qualification instead (for example https://qualification.bluetooth.com/ListingDetails/332380)? Including a host reference only helps us if we can use it in our own qualification.
==>[Christine]:Which host QDID can be referred to depends on which Zephyr Host Stack you are using. This link is only applicable to Zephyr RTOS LE host from the Linux Foundation. If you are referring to NXP Bluetooth Low Energy Host Stack Zephyr, then I do not recommend you to refer this link, but our NXP's QDID.

Thanks for your reply.
Yes, for sure, we have plan for the future Zephyr SDK. But for the detailed schedule, please allow me some time to check with our internal team.
Once have confirmed info, I will let you know.
BR,
Christine.
