DB command

This command reports the received signal strength of the last received RF data packet or APS
acknowledgment. The DB command only indicates the signal strength of the last hop. It does not
provide an accurate quality measurement for a multihop link.
The DB command value is measured in -dBm. For example, if DB returns 0x50, then the RSSI of the last
packet received was -80 dBm. Set DB to 0 to clear the current value, and it will be updated with the
next valid packet received.

PP command

Reads the dBm output when you select maximum power (PL4).
Note Read the maximum allowed power level when device is configured with PL=4. Use this command
to determine if the module is a Pro or non-Pro variant. The value the command returns will be in hex
representation: Pro = 0x14 and Non-Pro = 0x8.
