The client does not enter sleep mode as expected.

[Naveen Pyda]

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 Marte,

As you advised, we made the same changes in the script, but when we tried to flash, it failed with an error. Please find the attached logs for your reference.

Hi Mate,

As per your advice, we made the same changes in the script, and the flash build completed successfully. However, we are still not seeing the expected logs. After enabling TWT power save, the client only sends PS-Poll frames.

The following command was used:

 wifi twt setup 0 0 1 0 0 0 1 1 10000 1000000 100

Please find the attached PCaps for your reference.

Hi Marte,

Please respond. We are waiting for your reply.

Hi Merta,

Any updates on this?
