Module ssdp 

SSDP: answering M-SEARCH for local renders, and searching for devices.

Constants

MULTICAST_IP

PORT

Functions

search

serve_forever

Answer M-SEARCH requests forever. If the SSDP port can’t be bound (e.g. another listener holds it exclusively), keep retrying so this process takes over once the other one exits.
