Hi Controllers Tech! Great videos, I've been learning a lot from them. I have two questions:
1. Have you used the "KEEP ALIVE" function?. Everytime I disconnect and connect the server, the board is unable to reconnect to it.
Can you give some advice, i see there are many people have this problem

Thank you so much for the great video.
I followed the steps, and the program works fine except that I need an important additional feature.
I want the client to keep trying to connect to the server even if the server temporarily goes down (static ip) or the cable is unplugged.
I tried checking the tcp_client_sent and if the data is not sent, I tcp_client_init(). The latter causes a hard fault if it keeps doing for a few seconds. Also the whole method does not work if the cable in unplugged/replugged.

Do you have any suggestion?

Hii I have 2 ethernet ports and they will be associated with each other to communicate. Therefore, I have two drivers as client and server. According to my searchs I need to put accepted() and connect() functions to these drivers. But Im not exactly sure that. Can u help me to be able to make a port as server and another one is client in order to have dat flow between each other.
