SW (Reference Signal Received POWER)
Returns the Reference Signal Received Power (RSRP) value.
The value returned is in hex, and should be converted by the user with the following formula:
RSRP = -(<hex_value> / 0xA)
Example: The value returned from the command is 384:
RSRP = -(0x384 / 0xA) = -90.0 dBm
Example: The value returned is A0:
RSRQ = -(0xA0 / 0xA) = -16.0 dB
If the value cannot be retrieved for some reason, such as the device is not on the network yet, an
empty string with OK after it is returned.
