MT (Multi-transmit)

This command applies to the XTC RF Module.

Enables multiple transmissions of RF data packets. When you enable Multi-transmit mode (MT > 0), packets do not request an ACK from the receiving devices. MT takes precedence over RR, so if both MT and RR are non-zero, then a device sends MT+1 packets with no ACK requests.

When a receiving device receives a packet with remaining forced retransmissions, it calculates the length of the packet and inhibits transmission for the amount of time required for all retransmissions. From that time on, the device inserts a random number of delay slots between 0 and RN before allowing transmission from the receiving devices. This prevents all listening devices from transmitting at once upon conclusion of a multiple transmission event (when RN > 0).

Note The actual number of forced transmissions is the parameter value plus one. For example, if MT = 1, a devices sends two transmissions of each packet.
