Wi-Fi Radio AT Commands#

Commands#

• wifi-listen-interval

• wifi-get-listen-interval

wifi-listen-interval#

Set the Wi-Fi listen interval for the Si91x device.

Command Format#

at+wifi-listen-interval=<wifi-interface>,<listen-interval>,<listen-interval-multiplier>

Related SDK API#

sl_wifi_set_listen_interval_v2

Pre-conditions#

• net-init

• This should be called before net-up

Parameters#

wifi-interface#

The Wi-Fi interface type for which the listen interval needs to be set. Contains a numeric value that corresponds to one of the values of the enum sl_wifi_interface_t. Note some values are not currently supported, as indicated in the linked documentation.

Note: The enum values of sl_wifi_interface_t are not in the default numerical order of an enum. See sl_wifi_constants.h for the actual numeric values in this enum.

listen-interval#

The Listen Interval in milliseconds that is to be configured after multiplying it by the listen-interval-multiplier (see below) with the Access Point (AP) while joining the AP (when the net-up command is sent).

listen-interval-multiplier#

Optional. Multiplier for the listen-interval, sent by the device in the association request to the Access Point while joining (when the net-up command is sent). Multiplier will be set to 1 if this argument is omitted. Maximum value recommended is 10. Higher values may lead to interoperability issues.

Response#

• OK on success

• ERROR <error code> in case of failure. Possible error codes are the same as those returned by the sl_wifi_set_listen_interval_v2 API.

Examples#

// Set the Listen Interval to 1 second and Listen Interval Multiplier to 2 for the Wi-Fi client interface (Listen Interval of 2 seconds sent to AP while joining)
at+wifi-listen-interval=1,1000,2

wifi-get-listen-interval#

Queries the listen interval currently configured for the SiWx91x Wi-Fi client (station) by its connected Access Point.

Command Format#

at+wifi-get-listen-interval=<interface>

Related SDK API#

sl_wifi_get_listen_interval_v2

Pre-conditions#

• net-init

Parameters#

interface#

The Wi-Fi client interface for which the listen interval is to be queried. Contains a numeric value that corresponds to one of the values of the enum sl_wifi_interface_t. Note some values are not currently supported, as indicated in the linked documentation.

Note: The enum values of sl_wifi_interface_t are not in the default numerical order of an enum. See sl_wifi_constants.h for the actual numeric values in this enum.

Response#

• OK <listen-interval> <listen-interval-multiplier> in case of success, where:

  • <listen-interval> is the listen interval in milliseconds that is currently configured for the SiWx91x Wi-Fi client (station) by its connected Access Point.

  • <listen-interval-multiplier> is the number by which the <listen-interval> sent in the wifi-listen-interval value was multiplied and the resulting value sent to the Access Point.

• ERROR <error code> in case of error. The error codes returned are the same as those returned by the sl_wifi_get_listen_interval_v2` API.

Examples#

at+wifi-get-listen-interval=1
OK 1000 1
