UDP MULTICAST
=============
Use UDP MULTICAST connections to communicate between two devices in different networks
with IP-addresses 172.16.55.55 and 192.168.44.44.
Run `udp_multicast_client.py <https://github.com/micropython/micropython/blob/master/examples/network/udp_multicast_client.py>`_ on one device.
Client send GET and receive ACK from the server.
Output is::
GET to ('224.0.0.111', 5555) sent "client_ip:172.16.55.55 mac:b8-d6-1a-5a-c2-e4"
ACK from ('192.168.44.44', 5555) received "server_ip:192.168.44.44 mac:24-6f-28-7a-f3-9c"
GET to ('224.0.0.111', 5555) sent "client_ip:172.16.55.55 mac:b8-d6-1a-5a-c2-e4"
ACK from ('192.168.44.44', 5555) received "server_ip:192.168.44.44 mac:24-6f-28-7a-f3-9c"
...
Run `udp_multicast_server.py <https://github.com/micropython/micropython/blob/master/examples/network/udp_multicast_server.py>`_ on another device.
Server receive GET and send ACK to the client.
Output is::
GET from ('172.16.55.55', 5555) received "client_ip:172.16.55.55 mac:b8-d6-1a-5a-c2-e4"
