# W5500 ethernet modul with stm32 cube ide debugger....

## Question

Asked by akala19471989 on 2024-05-21 in Ethernet Chips.

Hello, I am using the w5500 ethernet module with the stm32cube ide program.
When I connect to the internet via the w5500 ethernet module stm32cube ide debugger, the return connect returns the value 252. What does this 252 value mean? Can you help me with this? There is no such value in the socket.h file.
