Thanks for help, but

I think there is a misunderstanding , my question: what is the fuction of SPI_Ethernet_userTimerSec and what is the effect on Spi_Ethernet_sendUDP

Thanks

Hello,

Global library variable SPI_Ethernet_userTimerSec is used to keep track of time for all client implementations (ARP, DNS, UDP and DHCP). It is user responsibility to increment this variable each second in it's code if any of the clients is used.

This means if MAC address does not get resolved during call of Spi_Ethernet_sendUDP and this variable does not get incremented, your program will stay locked trying to reach timeout.

Best regards.
