RR (Unicast Mac Retries)

This command applies to the XTC RF Module.

Sets or displays the maximum number of retries sent for a given RF packet. When you enable RR (RR > 0), it enables RF packet retries and ACKs.

Exceptions: If you enable the MT command (MT > 0) or if you use a broadcast destination address (DT = 0xFFFF) it disables RF packet retries and ACKs.

After transmitting a packet, the transmitting device waits to receive an ACK from a receiving device. If it does not receive the ACK in the time that RN specifies, it transmits the original packet again. The transmitting device transmits the RF packet repeatedly until it receives an ACK or until it sends the packet RR times.

Note You must have retries enabled for all modules in the network for retries to work.
