AT commands

TR (Transmission Failure Count)

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.
Parameter range
0 - 0xFFFF
Default
0

UA (MAC Unicast Transmission Count)

This count increments whenever a MAC unicast transmission occurs that requests an ACK. Once the
number reaches 0xFFFF, it does not count further events.
You can reset the counter to any 16-bit unsigned value by appending a hexadecimal parameter to the
command.
Parameter range
0 - 0xFFFF
Default
0

%H (MAC Unicast One Hop Time)

The MAC unicast one hop time timeout in milliseconds. If you change the MAC parameters it can
change this value.
Parameter range
[read-only]
Default
0xCF
0x267

%8 (MAC Broadcast One Hop Time)

The MAC broadcast one hop time timeout in milliseconds. If you change MAC parameters, it can
change this value.
Parameter range
[read-only]
Default
0x1BE
