problem with HUB
quangde opened this issue · comments
Hello all,
I have very stupid issue and I don't know why???
I ported picoTCP on STM32F4 and it works. Now I want to monitor the data exchange between Master(Server) and Slave (Client), thus I'm using simple HUB. The problem is: when the STM32F4 is plugged in ethernet HUB, I can not ping it from PC. I tried with Ethernet Router or direct with PC, it works again.
I know that I received the data from HUB, but it seems the sending back has problem because HUB can not forward them to PC.
Did somebody have same problem?
Thank you and have nice day.
