Hi all,
A few months ago, I created an application for nRF7002dk on nRF Connect SDK v2.3.0 that connected to a provided Wi-Fi network and then created four TCP and UDP sockets using the Posix API.
Now I am trying to migrate the project to nRF Connect SDK v2.4.2 and I have found that the Posix API I used to create the sockets and the WPA supplicant support I used to connect to the WiFi network are no longer compatible, so I cannot create the sockets successfully. How can I modify my application to get both features?
I tried to build the project using this prj.conf file, skipping the Posix API setting, but I was unable to create the sockets.
