Looks like it does - question then becomes do the existing libraries support that, or do you need to code something up?
6.4 Received Power Detector measurements
Received Power Detector (RPD), located in register 09, bit 0, triggers at received power levels above -64
dBm that are present in the RF channel you receive on. If the received power is less than -64 dBm,
RDP = 0.
The RPD can be read out at any time while nRF24L01+ is in receive mode. This offers a snapshot of the
current received power level in the channel. The RPD status is latched when a valid packet is received
which then indicates signal strength from your own transmitter. If no packets are received the RPD is
latched at the end of a receive period as a result of host MCU setting CE low or RX time out controlled by
The status of RPD is correct when RX mode is enabled and after a wait time of Tstby2a +Tdelay_AGC=
130us + 40us. The RX gain varies over temperature which means that the RPD threshold also varies over
temperature. The RPD threshold value is reduced by - 5dB at T = -40°C and increased by + 5dB at 85°C.
