    Hello Akihiko,

    Thanks for reaching out. Would you mind sharing what is the intent of using any of these values? As it says in the TRM they are all unique identifiers.

    Hello David,

    Thanks for your reply. I understood all of these number is unique.

    My customer wants to use this number as their board identifier before assigning and writing the Serial number in the Flash ROM.

    David,

    Our customer wants to know the range of "Unique" with ..uuid[8[, .dieId[16].

    Are these Identifier is unique across the all TI device or just only unique in CC2340R5 devices?

    Regards,

    Hello Akihiko,

    I believe it is unique across all devices, for instance, the dieId one includes date as part of the identifier. Also, the bleAddr is unique among devices as it is a BLE Public Address.
