Db (Received Signal Strength); Ea (Mac Ack Timeouts); Er (Received Error Count); Gd (Good Packets Received) - Digi XLR PRO User Manual

AT commands

DB (Received Signal Strength)

Reports the RSSI in -dBm of the last received RF data packet. DB returns a hexadecimal value for the -
dBm measurement.
For example, if DB returns 0x60, then the RSSI of the last packet received was -96 dBm.
DB only indicates the signal strength of the last hop. It does not provide an accurate quality
measurement for a multihop link.
Parameter range
0 - 0xFF [read-only]
Default
N/A

EA (MAC ACK Timeouts)

Reports or resets the total number of MAC-level unicast transmissions that timed out waiting for a
MAC ACK. The total can be up to RR (unicast retries) + 1 timeouts per unicast, up to a maximum of
0xFFFF. After 0xFFFF, additional retries are not counted. You can reset the counter to any 16-bit value
within the valid range by appending a hexadecimal value to the EA command.
EA is a volatile value—that is, the value does not persist across device resets.
Parameter range
0 - 0xFFFF
Default
N/A

ER (Received Error Count)

Reports or resets the total number of received packets that were rejected because of bit errors in the
packet, up to a maximum of 0xFFFF errors. After 0xFFFF, additional errors are not counted.
(Occasionally, random noise can cause a packet to be rejected.) You can reset the counter to any 16-
bit value within the valid range by appending a hexadecimal value to the ER command.
ER is a volatile value—that is, the value does not persist across device resets.
Parameter range
0 - 0xFFFF
Default
0

GD (Good Packets Received)

Reports or resets the total number of successfully received packets that contain a valid MAC header,
up to a maximum of 0xFFFF packets. After 0xFFFF, additional successfully received packets are not
counted. You can reset the counter to any 16-bit value within the valid range by appending a
hexadecimal value to the GD command.
GD is a volatile value—that is, the value does not persist across device resets.
