MK (Address Mask) Command

<Networking and Security> The MK command is used to set/read the Address Mask of a module.
All RF data packets contain the Destination Address of the TX (transmitting) module. When a packet is received, the TX
module Destination Address is logically "ANDed" (bitwise) with the Address Mask of the RX (receiving) module. The
resulting value must match the Destination Address or Address Mask of the RX module for the packet to be received
and sent out the RX module's DO (Data Out) pin. If the "ANDed" value does not match the Destination Address or
Address Mask of the RX module, the packet is discarded.
Sniffer Mode (when MK = 0): ACK requests are ignored and every RX (receive) frame is sent to the UART, without
regard for repeated frames.
All "0" values are treated as irrelevant values and ignored.

MT (Multi-transmit) Command

<Networking and Security> The MT command is used to enabled multiple transmissions of RF data packets. When
Multi-transmit Mode is enabled (MT > 0), packets do not request an ACK (acknowledgment) from the receiving RF
module(s). MT takes precedence over RR, so if both MT and RR are non-zero, then MT+1 packets will be sent (with no
ACK requests).
When a receiving module 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. Thereafter, a random
number of delay slots are inserted between 0 and RN before transmission is allowed from the receiving module(s).
This prevents all listening modules 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, two
transmissions of each packet will be sent.
