RSSI CHARACTERISTICS
Measured on Texas Instruments CC2540 EM reference design with TA = 25°C and VDD = 3 V
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
High-gain mode –99 to –44
Useful RSSI range(1) dBm
Standard mode –90 to –35
Absolute uncalibrated RSSI accuracy(1) High-gain mode ±4 dB
Step size (LSB value) 1 dB
(1) Assuming CC2540 EM reference design. Other RF designs give an offset from the reported value.
According to the data before,i dont know how to transform RSSI got by BTool into dB form??
Because now i write some experiment report and need to clearly explain the RSSI.
