sl_si91x_configure_timeout#

sl_status_t sl_si91x_configure_timeout (sl_si91x_timeout_type_t timeout_type, uint16_t timeout_value)

This API is used to set different module timeouts.

Parameters
[in]timeout_type

It is used to identify which timeout type to be set. The possible values can be sl_si91x_timeout_type_t

[in]timeout_value

timeout value to be set. The time resolution depends on timeout_type.

Note

  • After a successful IP configuration, Gratuitous ARP is used as the periodic WLAN Keep-Alive packet with the configured keep_alive_timeout interval.

    • If there is no IP configuration, the NULL Data Packets is used as the WLAN Keep-Alive packet.

Returns

sl_si91x_set_timeout#

void sl_si91x_set_timeout (sl_si91x_timeout_t *timeout_config)

Si91x specific set timeout.

Parameters
[in]timeout_config

Timeout configuration of type sl_si91x_timeout_t.

This function is used to set active channel scan timeout, authentication association timeout and keep alive timeout of module. Returns

  • None

Note

  • This API should ONLY be called before sl_wifi_init and repeated call to this API will overwrite timeout values stored in SDK, will be applied on next call to sl_wifi_init.
