wifi-perf-prof#

Configures the power and performance profile of the network processor of the SiWx91x device.

Command Format#

at+wifi-perf-prof=<profile>,<dtim-aligned-type>,<num-of-dtim-skip>,<listen-interval>,<monitor-interval>

Related SDK API#

sl_wifi_set_performance_profile_v2

Pre-conditions#

• net-init

Parameters#

profile#

The power or performance mode to set for the network processor of the SiWx91x device. Contains a numeric value that corresponds to one of the values of the enum sl_si91x_performance_profile_v2_t.

dtim-aligned-type#

Optional. The type of Listen Interval alignment, which can be set either to the number of DTIM beacons or the number of regular beacons. This setting is represented by a numeric value that corresponds to one of the permitted DTIM Alignment Type values.

num-of-dtim-skip#

Optional. The number of DTIM intervals to skip.

listen-interval#

Optional. Listen Interval expressed in the number of beacons of the type set by dtim-aligned-type.

monitor-interval#

Optional. Monitor Interval in milliseconds. Used when profile is set to Associated Power Save with Low Latency.

Notes#

• Parameters related to Target Wake Time are currently unsupported.

Response#

• OK in case of success,

• ERROR <error code> in case of error. The error codes returned are the same as those returned by the sl_wifi_set_performance_profile_v2 API.

Examples#

// Associated Power Save with Listen Interval set to 10 beacon intervals
at+wifi-perf-prof=1,0,0,10,0  

wifi-perf-prof?#

Queries the power and performance profile of the network processor of the SiWx91x device.

Command Format#

at+wifi-perf-prof?

Related SDK API#

sl_wifi_get_performance_profile_v2

Pre-conditions#

• net-init

Parameters#

None

Notes#

• Parameters related to Target Wake Time are currently unsupported.

Response#

• OK <profile> <dtim-aligned-type> <num-of-dtim-skip> <listen-interval> <monitor-interval> in case of success, where:

  • profile is the power or performance profile currently active on the SiWx91x device, and populated with a numeric value corresponding to one of the values of the enum sl_si91x_performance_profile_v2_t.

  • dtim-aligned-type is the type of beacon that the Listen Interval value is based on, and populated with one of the numeric values of the DTIM Alignment Type.

  • num-of-dtim-skip is the number of DTIM Intervals to skip.

  • listen-interval is the Listen Interval expressed in the number of beacons of type specified by dtim-aligned-type.

  • monitor-interval is the Monitor Interval in milliseconds or 0 or 0 to indicate that is using the default value of 500 milliseconds.

• ERROR <error code> in case of error. The error codes returned are the same as those returned by the sl_wifi_get_performance_profile_v2 API.
