Bluetooth SIG Declaration and ETSI/FCC

Tom Fesenmeyer

Hi,

we are about to enter bluetooth and expand our products with it. however, the approval process still raises some questions.

What I have understood so far (please correct if I am wrong) is that at the end a qualification and a declaration must be made at the Bluetooth SIG in addition to the normal ETSI/FCC qualification.
If a Product has an declaration ID, I can list other products that use the same Bluetooth hardware/software design under that ID. This makes it possible to pay only once for e.g. one product family. Aswell if I have some customer specific software on the application layer.

Now, the unclear things are:

1. If I use a Bluetooth-Modul like the Laird BL652 which is an allready certificated Bluetooth product with an existing QD ID, can I just refer to that ID and get my qualification process done without going to an accredited laboratory for the RF-PHY test? Or do I need to refer to the spezific testprotokoll of the Laird-Modul with alle the guidlines they discribe and my own design?

2. Whats the case when we use a Nordic chip with the recommended design described in the datasheet with also its own QD ID and if we have to do a qualification in a BQTF?

3. I've read that Nordic does bluetooth qualification pre-qual tests of customer designs for free, is that true?

4. If we do such a qualification can we save money when we use the service of pre-qual testing from Nordic?

5. Does Nordic also offer this service for a Modul which uses their chip? Or in a specific case like in LEGIC-6000 if a chip manufacturer uses the Nordic chip inside his own chip?

6. Can we use the RF-PHY test to save money in the ETSI/FCC qualification?

Thank you for help!

Greetings

Tom

    Hi,

     

    1. I believe you just refer to that ID, yes. You might want to run it by the module producer though as we really have little experience with qualifying their products.

    2. If you follow our reference design closely you can list your product and refer to our end-product QDID. We still recommend that you test the RF-PHY to have your back covered. No need to re-qualify, just test and save the logs.

    3. Not exactly, we can test the RF performance of your design and suggest any BOM/PCB changes needed and tune your antenna. This to make sure that when you apply for regulatory certification (FCC/ETSI) your design is optimized for best possible performance and is compliant with regards to harmonic and spurious emissions, meaning you should not run any risk of failing the certification.

    4. Only if you otherwise would have failed the certification, meaning you would need to make changes to your design and reapply.

    5. In practice no, we can not make any changes to the module.

    6. Unless you get a 'volume discount' at the test house: no, these are different tests.

     

    Best regards,

    Andreas
