CC2651R3SIPA: Confirmation Regarding Radio Law Certification for CC2651R3SIPA with SDK 7.41.00.17

Thank you for your response.

We apologize, but we are having difficulty understanding your answer.

We have been downloading the SDK from the following website:
https://www.ti.com/tool/download/SIMPLELINK-LOWPOWER-F2-SDK/7.41.00.17
However, we could not find a version labeled 7.20.00.00 on this site.

Is there a special procedure to download version 7.20.00.00?
Also, could you please clarify whether 7.20.00.00 refers to the SDK version?

We would greatly appreciate your guidance.

Best regards,

Hi !

Sorry for my previous answer, I was mistaken on how certifications worked. 7.20 was the version of the certification and not the SDK, sorry for that.

I will ask for more about information about how certifications work and will get back to you quickly.

Kind regards,
Maxence

Hello Hiroki,

Thanks for reaching out.

May I ask if you are looking for Bluetooth LE certification or if this is a proprietary RF type of wireless implementation?

For Bluetooth LE, I would suggest to look into this app note where we explain in detail about BLE qualification and which we keep updated with the latest BLE qualification numbers.

BR,

David.

Dear David,

Thank you for your reply.

We are currently developing a BLE device based on the Simple Peripheral example from SDK version 7.41.00.17.
The BLE implementation uses APIs provided by the BLE5Stack library included in this SDK, and it is working as expected.

Our concern is whether the BLE5Stack library and this SDK version are covered under the existing radio certification for the CC2651R3SIPA.
We understand that the CC2651R3SIPA has already been certified under regulatory standards such as Japan's Radio Law, and we believe that this certification may include the software stack as well.

Could you please confirm:

• Whether SDK version 7.41.00.17 is included in the scope of the certified software, or

• Whether a new certification process is required if we use this SDK version, and

• If needed, would switching to a different SDK version help avoid the need for re-certification?

We appreciate your guidance on this matter.

Best regards,
Hiroki

Hello Hiroki,

Apologies for the delay here.

I believe Table 2-4 in this app note: How to Certify Your Bluetooth Product answers your question for the device you are asking about.

Please let me know if you have further questions.

BR,

David.

I'm Katsura, working together with Hiroki-san.
I reviewed your app note and have one question regarding Bluetooth certification.

We have checked the design guidelines for the CC2651R3SIPA from the associated TI reference design (sipa.pdf).
Due to our enclosure design, we may need to change the board layout from the recommended RF layout.

As the "CC2651R3SIPA" is already qualified under the "End Product Listing," we understand that if we follow the reference design without any board layout changes, certain testing including RF-PHY can be skipped.

However, if we do change the board layout, are we required to perform all tests, including RF-PHY, through a Bluetooth Qualified Test Facility (BQTF)?

We would appreciate your clarification.

Best regards,

Dear David,

How about the answer to my previous question?

Dear David and TI teams,

Could you reply to following question in previous message?

Dear David and TI teams,

Could you please answer the question I sent earlier?

Hello Toshio,

I am very sorry I have missed this. I believe this will be the case, depending on the extension of the board layout modifications. However to be sure about this, I am assigning the thread to a HW expert to confirm your question.

Thanks.

David.

Dear David,

Thank you for reply, please let us know.

Hi,

Regard the layout changes, if the RF path does not change and you pick from one of our certified antennas, then no re-certifications are required. However, if the RF path and antenna does changes, provide the details here and I can assist you in determining if a Class II Permissive Change is needed.

Best regards,

Bun

Thank you for your reply.

Due to PCB size limitations, we're planning to modify the RF path and antenna design from TI's recommendations.
We haven't finalized the PCB design yet, and we anticipate locking down the RF path and antenna specifics in a few months.

Regarding how to provide you with the details.
From a design disclosure perspective, we would prefer to send the detailed files directly to you, not forum.
Please let us know.

If that is the case, then submit a design review here when you are ready: https://www.ti.com/tool/SIMPLELINK-2-4GHZ-DESIGN-REVIEWS

I will review it with special attention to the RF path and give you feedback on how to avoid a Class II Permissive Change, if possible.
