hello all!!
i'm trying to create a client, client/server, server system.
in the middle ESP i want to use AP_STA mode, and he need to connect to the server and be a server for the other client.
i have a messy code but the big problem i'm thinking is the ip... anyone do it before? can i see a working code?
this is my client/server code:
look on the setup....
i forget to tell that i dont konw nothing about IP so maybe the ip is forbidden...
edit: i'm sorry, i found the wifi.APConfig and how to change the ip...
you can remove this post...
best regard,
