CC2640R2F: Correct QDID for Qualification

Part Number: CC2640R2F
Other Parts Discussed in Thread: BLE-STACK,

Good day!

I am working through the Bluetooth qualification process, and we may use the CC2640R2F chip, with the  v4.2 BLE-Stack library (SDK 5.10 and later).  Our application is based on the simple_peripheral project, but we modify the device name, characteristic UUIDs, lengths, data values, etc.

In looking at the SWRA601H qualification guide (https://www.ti.com/lit/an/swra601h/swra601h.pdf), I think we will need to reference either:

  • QDID 180401 (Central, Peripheral, Multirole - BLE-Stack 3.3.x (SDK 5.10 and later)), or
  • QDID 135680 (BLE-Stack 3.3.x (SDK 3.20 and later))

Does this understanding sound correct?  If so, which QDID would be applicable for our application?

As a related question... when would QDID 176642 be applicable (RF-PHY component listing)?  We use a custom PCB in our design.

Thanks a ton!

  • Hey Kenton,

    • QDID 180401 (Central, Peripheral, Multirole - BLE-Stack 3.3.x (SDK 5.10 and later)), or
    • QDID 135680 (BLE-Stack 3.3.x (SDK 3.20 and later))

    Does this understanding sound correct?  If so, which QDID would be applicable for our application?

    The difference between the two QDIDs listed is that QDID 180401 is an End Product listing, and the other, QDID 135680 is a Component listing. Generally, the end product listing includes the stack along with external hardware on our development Launchpad Kits. If your custom design diverges from our Launchpad in terms of external hardware (i.e. antenna/RF design), I believe you will have to use the Component listing (i.e. use QDID 135680) and requalify for the End Product, since the End Product is different than what was qualified in QDID 180401.

    As a related question... when would QDID 176642 be applicable (RF-PHY component listing)?  We use a custom PCB in our design.

    The RF-PHY component listings are generally reserved for certain devices, mainly SOCs with RF integrated into the chip. I think you will have to re-certify your custom PCB and perform RF-PHY qualification on your new design. In this case, the QDID 176642 should not be used.

    I've assigned an expert to further comment and make any clarifications/corrections to my statement above.

  • Hi,

    To complete Ammar's answer, I would recommend to leverage the end product listing QDIDs when possible - the qualification process is easier and cheaper. Your Bluetooth Qualification Consultant (BQC) will assess if your design is is close enough and follows the design guidelines from the associated TI reference design.

    Best regards,

  • Thank you for the quick and thorough answer, Clement and Ammar!  

    Just to confirm... by "reference design", are you referring to the design in the CC2640FR2 datasheet (SWRS176B, section 7 - https://www.ti.com/lit/ds/symlink/cc2640.pdf), or one of the commercial development boards?

    Thanks again,

  • Hi Kenton,

    y "reference design", are you referring to the design in the CC2640FR2 datasheet (SWRS176B, section 7 - https://www.ti.com/lit/ds/symlink/cc2640.pdf), or one of the commercial development boards?

    I actually recommend to review first https://www.ti.com/lit/swra640.
    The reference designs in the datasheet and the LAUNCHXL-CC2640R2 should be pretty similar (and follow the guidelines suggested in the previous document). For your information, the end product listing QDID has been obtained using a LAUNCHXL-CC2640R2.

    Once again, make sure to leverage the help of your Bluetooth Qualification Consultant (BQC). She/He will help to assess if TI's end product listing QDID can be leveraged and which level of additional testing is required.

    Best regards,
