--------
|

This configuration exercises netutils/discover utility using
|
||||
apps/exmaples/discover. This example initializes and starts the UDP
|
||||
discover daemon. 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.
|
||||
|
||||
Configuration settings that you may need to change for your
|
||||
environment:
|
||||
|

CONFIG_STM32_CODESOURCERYL=y - CodeSourcery for Linux
|
||||
CONFIG_EXAMPLE_DISCOVER_DHCPC=y - DHCP Client
|

CONFIG_EXAMPLE_DISCOVER_IPADDR - (not defined)
|
||||
CONFIG_EXAMPLE_DISCOVER_DRIPADDR - Router IP address
|

NOTE: This configuration uses to the mconf configuration tool to control

the configuration. See the section entitled "NuttX Configuration Tool"
