TR (Transmission Failure Count)

This command applies to the XTC RF Module.

Reads the number of RF packets where retries expire without receiving an ACK (when RR > 0).

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.

This value is volatile (the value does not persist in the device's memory after a power-up sequence).
