The client does not enter sleep mode as expected.

We are using the Nordic Semiconductor nRF7002-DK. In this board, both PS-Poll and No-PS-Poll power-saving modes are working as expected. However, when running in TWT (Target Wake Time) power mode using the following command:-wifi twt setup 0 0 2 2 0 1 1 1 1000 60000, the client does not enter sleep mode as expected. Can you help us to enter the device into sleep mode.

Applications Versions: 

1. nRF connection Desktop v5.2.0
2. Toolchain Manager v1.6.0
3. Visual studio cade v2.9.2
4. Windows 11 pro Platform

Hi,

First, the TWT interval is in microseconds, so setting it to 60000 equals 0.06 seconds. This interval is the total TWT interval, i.e., both wake-up time and sleeping time. I would recommend increasing it, for example, to 6000000 instead.

Can you verify that the device does not enter sleep mode by measuring the power consumption or checking the sleep state using NET_EVENT_WIFI_TWT_SLEEP_STATE? You can see examples of how to check the sleep state in the TWT sample (see https://github.com/nrfconnect/sdk-nrf/blob/v2.9.2/samples/wifi/twt/src/main.c#L306) and in Lesson 6 exercise 2 - Enabling TWT with notification in our Wi-Fi Fundamentals course on DevAcademy. The latter also shows how to measure power consumption.

Best regards,
Marte

Hi Marte,

Apologies for the delayed response. I did try setting the interval to 6000000 as you suggested, but unfortunately, the client still does not enter the sleep state. It continues to stay awake

For your reference I had attached the pcaps below.

Hi,

Please verify that the device does not enter sleep state by measuring the power consumption or checking the sleep state using NET_EVENT_WIFI_TWT_SLEEP_STATE as I mentioned in my previous reply.

Best regards,

Hi,

As you advised, we followed the link https://academy.nordicsemi.com/courses/wi-fi-fundamentals/lessons/lesson-6-wifi-fundamentals/topic/lesson-6-exercise-2-2/nk, but we are still facing the same issue.

Thanks & Regards,

Hi Naveen,

Did you test by measuring the power consumption and/or checking the sleep state using NET_EVENT_WIFI_TWT_SLEEP_STATE?
