CC2540 ETSI Classification

Other Parts Discussed in Thread: CC2540

Hello,

according to the documentation about Bluetooth Low Power technology the device CC2540F256 should be classified by ETSI normes as the system using DSSS (Direct-sequence spread spectrum) modulation because Bluetooth LE does not satisfy conditions of FHSS (Frequency-hopping spread spectrum) modulation. But ETSI then requires to classify the device as adaptive or non-adaptive. From the datasheets available for CC2540F256 it is not clear to me how it should be classified by this criterium. Does anybody have some experience with this? Does it depend maybe on the configuration of the microcontroller or it is done by the built-in Bluetooth LE periphery?

Regards.

    For Short Range Devices operating in the 2.4GHz ISM band the relevant Harmonized Standards are::

    • EN 50371 - compliance to human exposure to electromagnetic fields'
    • EN 300 328 - radio equipment testing of data transmission equipment operating in the 2.4GHz ISM
    • EN 301 489 - electromagnetic compatibility

    The CC2540 would have adaptive hopping
