Good morning everyone,

I'm currently working on a project with a ST32 and my goal is to be able to give him simple instruction in Modbus TCP/IP thanks to an Ethernet cable. Presently I've been able to code functions in order to get the frame sent to my ST32, check the MAC and IP adresses and the different headers. The only problem is that now, I would like to be able to confirm the good reception of the frame for example when i get a frame in ARP protocole, I'm supposed to answer back with my MAC addresse.
So far I've been reading the reference Manual but the algorythms it gives are pretty blur to me... and so are the different functions proposed in the ETH ST library... If someone had an idea of how I should proceed it would help me very much !
