# Netx Duo Udp ## Overview The netx duo udp example shows netx udp send and receive functions. ## Board Setting - Connect an Ethernet port on PC to a RGMII port or a RMII port on the development board with an Ethernet cable ## Project Configuration - Ethernet Port Settings: Refer to [Ethernet common project settings](../../../../lwip/doc/Ethernet_Common_Project_Settings_en.md) - By Setting `CONFIG_NETX_ENABLE_DHCP` to zero or comment the definition code in CMakeLists.txt, the DHCP will be disabled - When DHCP is disabled, comment or delete `set(CONFIG_ECLIPSE_THREADX_NETXDUO_ADDONS_DHCP 1)` can decrease project source files number ## Running the example When the example runs successfully, it will send udp message **"ABCDEFGHIJKLMNOPQRSTUVWXYZ "** to **ECHO_SERVER_ADDRESS : ECHO_SERVER_PORT**(192.168.1.2:7777) through port **ECHO_SEND_PORT**(7777) and then wait for receive udp message with a timeout. It will print phy link status periodically until its status becomes **Up**. If received udp message, it will also print it to the console. Following message is displayed in the terminal: ```console NetXDuo is running IP address: 192.168.1.223 Mask: 255.255.255.0 Enet phy init passed !
