Memory requirements for Wi-Fi applications in Station mode
Code and RAM memory footprint requirements differ depending on the selected platform and the application example.
The following tables list memory requirement values for selected Wi-Fi® samples supporting Station mode.
Footprint values are provided in kilobytes (KB).
