Query Current RSSI Value
Description:
To determine the current Receive Signal Strength Intensity, RSSI, value for the current channel being
scanned, register S202 can be read. The RSSI value is presented as the relative signal strength above
the modem noise floor. The absolute value is determined by adding the relative value from register S202
to the noise floor value of –115 dBm.
It is important to remember that the modem can be scanning while this inquiry is made, thus the value
read back may not be valid for the channel that is later retrieved from the current channel register.
Format:
