TWT (Target Wake Time) request structure to auto select a session.
Public Attributes#
TWT enable. 0 - TWT session teardown; 1 - TWT session setup.
This is the expected average Tx throughput in Kbps. Value ranges from 0 to 10 Mbps, which is half of the default device_average_throughput (20 Mbps by default).
The allowed latency, in milliseconds, within which the given Tx operation is expected to be completed. If 0 is configured, maximum allowed Tx latency is same as rx_latency. Otherwise, valid values are in the range of [200 ms - 6 hrs].
The maximum latency, in milliseconds, for receiving buffered packets from the AP. The device wakes up at least once for a TWT service period within the configured rx_latency if there are any pending packets destined for the device from the AP. If set to 0, the default latency of 2 seconds is used. Valid range is between 2 seconds to 6 hours. Recommended range is 2 seconds to 60 seconds to avoid connection failures with AP due to longer sleep time.
Refers to the average Tx throughput that the device is capable of achieving in Kbps. The default value is 20 Mbps. Internal SDK use only: do not use.
The percentage by which wake duration is supposed to be overestimated to compensate for bss congestion. Recommended input range is 0 - 50%. The default value is 0. Internal SDK use only: do not use.
The allowed deviation percentage of wake duration TWT response. Recommended input range is 0 - 50%. The default value is 10. Internal SDK use only: do not use.
Default minimum wake interval. Recommended Range: 512 to 1024 ms. The default value is 1024msec. Internal SDK use only: do not use.
Default minimum wake interval. Recommended Range: 8- 16 ms. The default value is 8 ms. Internal SDK use only: do not use.
The number of beacons after the service period completion for which the module wakes up and listens for any pending RX. The default value is 2. Internal SDK use only: do not use.
