Bc (Bytes Transmitted); Db (Last Packet Rssi); Ea (Mac Ack Failure Count) - Digi XTend vB DigiMesh XTP9B-DPM-001 User Manual

Default
N/A

BC (Bytes Transmitted)

The number of RF bytes transmitted. The firmware counts every byte of every packet, including MAC/PHY
headers and trailers. The purpose of this count is to estimate battery life by tracking time spent
performing transmissions.
This number rolls over to zero from 0xFFFF.
You can reset the counter to any 16-bit value by appending a hexadecimal parameter to the command.
Parameter range
0 - 0xFFFF
Default
0

DB (Last Packet RSSI)

This command reports the received signal strength of the last RF data packet that a device receives. The
DB command only indicates the signal strength of the last hop. It does not provide an accurate quality
measurement for a multihop link.
If the device has been reset and has not yet received a packet, this variable reports 0.
The command measures RSSI in -dBm. For example if DB returns 0x60, then the RSSI of the last packet
received was -96 dBm.
Parameter range
0x28 - 0x6E
Default
0x8000

EA (MAC ACK Failure Count)

This count increments whenever a MAC ACK timeout occurs on a MAC-level unicast. When the number
reaches 0xFFFF, the firmware does not count further events.
To reset the counter to any 16-bit value, append a hexadecimal parameter to the command. This value is
volatile (the value does not persist in the device's memory after a power-up sequence).
