4.6.18 Report Last Valid RSSI
As RSSI values are only valid when the local transceiver is receiving a RF packet from a remote
transceiver, instantaneous RSSI can be very tricky to use. Therefore, the transceiver stores the most
recent valid RSSI value. The Host issues this command to request that value. Note: This value will
default to FFh on a Client and 00h on a Server if no valid RSSI measurement has been made since
power-up. The Host issues this command to read the last valid RSSI:
Host Command:
Transceiver Response:
01/21/05
Byte 1 = CCh
Byte 2 = 22h
Byte 1 = CCh
Byte 2 = Data1
Where:
Data1 = Most significant 8 bits of last valid RSSI reading.
Note: Notice the trend between -9dBm and 7dBm does not follow the curve. This is because
the RSSI becomes saturated at signal levels above -40dBm.
