MK (Address Mask)

This command applies to the XTC RF Module.

Sets or read the device's Address Mask.

All RF data packets contain the Destination Address of the transmitting (TX) device. When a device receives a packet, the TX device's Destination Address is logically combined bitwise (in other words, joined with AND) with the Address Mask of the receiving (RX) device. The resulting value must match the Destination Address or Address Mask of the RX device for the packet to be received and sent out the RX device's DO (Data Out) pin. If the combined value does not match the Destination Address or Address Mask of the RX device, it discards the packet.

Sniffer mode (when MK = 0): the device ignores ACK requests and sends every RX (receive) frame out the UART, without regard for repeated frames.

The firmware treats all 0 values as irrelevant and ignores them. For more information, see Addressing.
