Point to Point / Point to Multipoint (P2MP)
This delivery method does not use a network header, only the MAC header.
In P2MP, the sending devices always send all messages directly to the destination. Other nodes do not repeat the packet. The sending device only delivers a P2MP unicast directly to the destination device, which must be in range of the sending device.
In P2MP mode, the originator sends a unicast packet directly to the destination device—which must be in range. All other devices in range ignore the unicast.
In P2MP mode the originator sends a broadcast MT+1 times, but the receiving nodes do not rebroadcast the packet. So, like the unicast transmission, the receiving device must be in range.
All devices that receive a P2MP broadcast transmission output the data through the serial port.
