CurrNwkAddr - this returns the address of the radio in its parent’s network.
CurrNwkID - this returns the ID of the network the radio is currently assigned to or connected to. A value
of 0xFF means the radio is scanning for a network but has not yet joined one.
of 0xFF means the radio is scanning for a network but has not yet joined one.
CurrRF_DataRate - this returns the RF data rate of the network that the radio is currently assigned to or
connected to. If the radio is scanning for a network, this is the current data rate it is using in the scan.
connected to. If the radio is scanning for a network, this is the current data rate it is using in the scan.
CurrFreqBand - this returns the frequency band of the network that the radio is currently assigned to or
connected to. A value of 0xFF means the radio is scanning for a network but has not yet joined one.

RemoteSlotSize - returns the current remote slot size, defined as the maximum number of message bytes
a remote can send on a single hop. When using protocol mode, the entire packet, including overhead
bytes must be less than or equal to this value or the packet will be discarded. In the three TDMA modes
the remote slot size is automatically computed, and this value is read-only. In polling and CSMA modes,
the remote slot size must be set by the user. The parameter to set this is CSMA_RemtSlotSize in Bank 1.

TDMA_NumSlots - in TDMA access modes, this returns the number of slots currently allocated.
TDMA_CurrSlot - returns the current TDMA slot number assigned to the remote in modes where the slot
position is automatically computed. In modes where this number is not applicable, it is read as 0xFF.

HardwareVersion - returns an identifier indicating the type of radio. A value of 0x41 is defined for the
CCT24 Rev A hardware.
CCT24 Rev A hardware.
FirmwareVersion - returns the firmware version of the radio in 2-digit BCD format.
FirmwareBuildNum - returns the firmware build number, in binary format.
SuperframeCount - returns the current superframe count. The count increments every 64 hops.
RSSI_Idle - returns the last measurement of RSSI made during a time when the RF channel was idle.
Can be used to assess the noise floor or detect interferers.

RSSI_Last - returns the last measurement of RSSI made during the receipt of an RF packet with a valid
CRC. Can be used for network commissioning and diagnostic purposes.

CurrTxPower - returns the current transmitter power setting of a remote, allowing the automatic power
setting to be tracked. This parameter is the nominal output power setting in dBm, and is a 2’s complement
value. Note that the CurrTxPower parameter value returned from a base or repeater is not valid.
