Part Number: CC2541

Hi, 

I have an equipment that has this chip.

I need to know if this chip supports adaptivity features. I mean, do I need to check adaptivity parameter agains ETSI EN 300 328 v2.1.1?

Thanks in advance,

    Hello User,
    The BLE stack on CC2541 only use channel hopping with fixed hop increment value set on each new connection. It should not fall under the category of adaptive frequency hopping. ETSI EN 300 328 v2.1.1 state in section 4.3.1.7.1 Applicability:
    "In addition, this requirement does not apply for equipment with a maximum declared RF Output power level of less
    than 10 dBm e.i.r.p. or for equipment when operating in a mode where the RF Output power is less than 10 dBm e.i.r.p. "

    The CC2541 can only be qualified for BT core spec 4.x and therefore must adhere to the maximum 10 dBm output power as stated in the BT Core spec (5.0) section 3 TRANSMITTER CHARACTERISTICS:
    "Note: The maximum output power for LE in v4.0, v4.1, and v4.2 is 10 mW."
