4.4 Received Signal Strength Indicator (RSSI)

Due to the external LNA and the offset in the CC2530, the RSSI readouts from the CC2530 - CC2592 are different from RSSI offset values for a standalone CC2530 design. The offset values are shown in Table 4.

Table 4. RSSI Compensation

Gain Modes RSSI Offset(1)
High Gain Mode 83
Low Gain Mode 78
(1) Real RSSI = Register value – RSSI offset
