ER (Received Error Count)
This command applies to the XBee SX 868 RF Module.
This count increments when a device receives a packet that contains integrity errors of some sort.
When the number reaches 0xFFFF, the firmware does not count further events.
To reset the counter to any 16-bit unsigned value, append a hexadecimal parameter to the
ERcommand.
Parameter range
0 - 0xFFFF
Default
0
GD (Good Packets Received)
This command applies to the XBee SX 868 RF Module.
This count increments when a device receives a good frame with a valid MAC header on the RF
interface. Once the number reaches 0xFFFF, it does not count further events.
Parameter range
0 - 0xFFFF
Default
0
EA (MAC ACK Timeouts)
This command applies to the XBee SX 868 RF Module.
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.
Parameter range
0 - 0xFFFF
Default
0
TR (Transmission Errors)
This command applies to the XBee SX 868 RF Module.
This count increments whenever a MAC transmission attempt exhausts all MAC retries without ever
receiving a MAC acknowledgment message from the destination node. Once the number reaches
0xFFFF, it does not count further events.
To reset the counter to any 16-bit value, append a hexadecimal parameter to the command.
