The maximum transmission power of the CC2531F128RHAR is +4.5 dBm.
To configure the CC2531F128RHAR for optimal power consumption, use the lowest possible transmission power, disable unnecessary peripherals, and use the device's power modes (e.g., sleep mode) when not transmitting or receiving data.
Yes, the CC2531F128RHAR can be used with an external antenna. However, the antenna must be designed to operate at the 2.4 GHz frequency band and must be matched to the device's 50-ohm impedance.
The CC2531F128RHAR supports frequency hopping through its Adaptive Frequency Hopping (AFH) feature. To implement frequency hopping, configure the device to use AFH and specify the hopping sequence and channel parameters.
The CC2531F128RHAR supports a maximum data rate of 2 Mbps.
