My fellow teachers, I use W5500 module from the upper machine data to the next bit machine stm32 board, PC data frequency is 200 ms pass, the next bit machine is 100 ms a closed then will receive data back to the PC, but the next bit machine often receive half of the data, how to solve? Thank you,

The use of tcpip protocol stack

reference 1/f, worldy response:

using tcpip protocol stack

I am using TCP/IP link, can be more specific?

CodePudding user response:

Didn't understand what is your connection hardware, I guess you W5500 is directly connected to the STM SPI,
Don't know what you are using the data transmission. TCP or UDP or other agreement,

Is the simplest use UDP to transfer, specific explanation in the official WIKI,

Have the UDP in official provide examples of code, you can reference,
