Custom Feature Bitmap#

SL_SI91X_CUSTOM_FEAT_DISABLE_GATEWAY_IN_RSI_AP#

#define SL_SI91X_CUSTOM_FEAT_DISABLE_GATEWAY_IN_RSI_AP

BIT(2)

Disables gateway configuration sent to STA from RSI AP.

If this bit is set to 1, the DHCP server behavior changes when the device is in Access Point (AP) mode. The DHCP server will assign IP addresses to client nodes without sending out a Gateway address, providing only the assigned IP and Subnet values. It is highly recommended to keep this value at '0' for standard AP functionality, as disabling the gateway address is typically needed only for very specialized use cases. The default value of this bit is '0'

Note

• Bits 0 - 1 are reserved.

SL_SI91X_CUSTOM_FEAT_DNS_SERVER_IN_DHCP_OFFER#

#define SL_SI91X_CUSTOM_FEAT_DNS_SERVER_IN_DHCP_OFFER

BIT(6)

Includes DNS server IP address in DHCP offer response when in AP mode.

When this bit is set, the DHCP server running in AP mode will include the DNS server IP address in the DHCP offer response sent to clients.

SL_SI91X_CUSTOM_FEAT_DFS_CHANNEL_SUPPORT#

#define SL_SI91X_CUSTOM_FEAT_DFS_CHANNEL_SUPPORT

BIT(8)

Enables scanning of DFS channels in the 5 GHz band.

SL_SI91X_CUSTOM_FEAT_ENABLE_AP_BLACKLIST#

#define SL_SI91X_CUSTOM_FEAT_ENABLE_AP_BLACKLIST

BIT(12)

Enables AP blacklisting in Station (STA) mode.

By default, the client maintains an AP blacklist to avoid specific access points. Enabling this feature allows the client to bypass the AP blacklist during roaming or rejoin, if needed.

SL_SI91X_CUSTOM_FEAT_MAX_NUM_OF_CLIENTS#

#define SL_SI91X_CUSTOM_FEAT_MAX_NUM_OF_CLIENTS

(max_num_of_clients)

Sets the maximum number of clients supported in AP mode.

This bit field sets the maximum number of clients that can be supported in Access Point (AP) mode. The value for this field should be provided in the range specified by bits 13 - 16.

SL_SI91X_CUSTOM_FEAT_ROAM_WITH_DEAUTH_OR_NULL_DATA#

#define SL_SI91X_CUSTOM_FEAT_ROAM_WITH_DEAUTH_OR_NULL_DATA

BIT(17)

Selects between de-authentication or null data (with power management bit set) for roaming.

If this bit is enabled then roam through DEAUTH, or roam through NULL.

SL_SI91X_CUSTOM_FEAT_TRIGGER_AUTO_CONFIG#

#define SL_SI91X_CUSTOM_FEAT_TRIGGER_AUTO_CONFIG

BIT(20)

Triggers automatic configuration.

This bit enables the auto-configuration feature, which allows the module to automatically configure itself based on predefined parameters.

Note

• Not applicable for SI917.

SL_SI91X_CUSTOM_FEAT_LIMIT_PACKETS_PER_STA#

#define SL_SI91X_CUSTOM_FEAT_LIMIT_PACKETS_PER_STA

BIT(22)

Limits the number of packets buffered per STA in AP mode.

In Access Point (AP) mode, if this bit is set, only two packets per Station (STA) will be buffered when the STA is in Power Save (PS) mode. This helps manage buffer usage and ensures efficient packet handling.

Note

• Bit 21 is reserved.

SL_SI91X_CUSTOM_FEAT_HTTP_HTTPS_AUTH#

#define SL_SI91X_CUSTOM_FEAT_HTTP_HTTPS_AUTH

BIT(23)
