FirmwareBuildNum - this parameter holds the firmware build number, in binary format.
FirmwareBuildDate - this parameter holds the date of firmware build in MM/DD/YY format.
FirmwareBuildTime - this parameter holds the time of the firmware build in HH:MM:SS format.
RssiIdle - this 2’s compliment parameter holds the last RSSI measurement in dBm made during a time
when the RF channel was idle. This parameter is useful for detecting interferers.
when the RF channel was idle. This parameter is useful for detecting interferers.
RssiLast - this 2’s compliment parameter holds the last RSSI measurement in dBm made during the re-
ceipt of an RF packet with a valid CRC. This parameter is useful for network commissioning/diagnostics.
ceipt of an RF packet with a valid CRC. This parameter is useful for network commissioning/diagnostics.
AvgBeaconPower - this 2’s compliment parameter holds the alpha-filtered beacon power (dBm) received
from a device’s parent, where alpha = 0.0625.
from a device’s parent, where alpha = 0.0625.
ParentMacAddress - this parameter holds the MAC address of a DNT24’s parent.
ModelNumber - this parameter specifies the DNT model, in this case a DNT24.
TxQueue - this parameter indicates if the transmitter queue is currently holding bytes to transmit.
If bytes are present in the queue the value is 1. If the queue is empty the value is 0.
If bytes are present in the queue the value is 1. If the queue is empty the value is 0.
