Note:

For Wi-Fi, the macros are set with the value “0” by default in the file wifi_config_default.h located in <SDK_PATH>/middleware/wifi_nxp/incl/ directory.

To enable the features, set the value of the macros to “1*” in the file wifi_config.h located in*<SDK_Wi-Fi_Example_PATH>/ directory***.***
Bluetooth

To enable the features, set the value of the macros to “1” in the file app_bluetooth_config.h located in <SDK_Bluetooth_Example_PATH>/ directory.

SLIM feature

The SLIM feature is used to reduce the consumption of the flash memory and SRAM of low-end boards like the FRDM MCXN947.

Memory impact:

SLIM macros	Feature disabled
CONFIG_WIFI_SLIM_ROAM	CONFIG_ROAMING CONFIG_11K CONFIG_11V CONFIG_11R
CONFIG_WIFI_SLIM_STA	CONFIG_5GHz_SUPPORT\ (applicable for RW612) CONFIG_CLOUD_KEEP_ALIVE CONFIG_WIFI_EU_CRYPTO CONFIG_TX_AMPDU_PROT_MODE CONFIG_WNM_PS CONFIG_TURBO_MODE CONFIG_AUTO_RECONNECT CONFIG_DRIVER_OWE CONFIG_OWE CONFIG_WIFI_FORCE_RTS CONFIG_WIFI_FRAG_THRESHOLD CONFIG_COMBO_SCAN CONFIG_SCAN_CHANNEL_GAP
CONFIG_WIFI_SLIM_UAP	CONFIG_UAP_STA_MAC_ADDR_FILTER CONFIG_WIFI_MAX_CLIENTS_CNT
CONFIG_FREERTOS_LOW_MEMORY_FOOTPRINT	When the macro is enabled, the heap memory usage is reduced by 10 KB (from 70 KB to 60 KB).
CONFIG_LWIP_LOW_MEM_FOOTPRINT	When the macro is enabled: The memory usage is reduced by curtailing LWIP stack parameters. The data throughput is reduced. Data net-stats are disabled.

[^1] The macro is not used for IW416.
