The RSSI value is returned in 2’s complement hex format. The RSSI value
in dBm can be calculated based on the formula shown below.
RSSI (dBm) = RSSI_value (in the response) - 256
This command only returns the ambient RSSI. The RSSI for a received
packet is included with the packet data. The response is only valid when
the radio state is set to RX On.

Figure 40: Restore Factory Default Configurations Command and Response
Once this command is issued and all non-volatile settings have been
restored, a power cycle restores all volatile settings to the factory defaults.
The module now works as it was originally shipped. The one exception is
that the module address is retained. This can be set to the default of 00 00
00 00 if desired.
The response parameter indicates if the command was successful (00) or if
there was an error (01).
