Network Utilities / discover

This daemon is useful for discovering devices in local networks, especially with DHCP configured devices. It listens for UDP broadcasts which also can include a device class so that groups of devices can be discovered. It is also possible to address all classes with a kind of broadcast discover.

See nuttx/tools/discover.py for a client example.
