After enabling TWT power save, the client only sends PS-Poll frames

[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 1 0 0 0 1 1 10000 1000000 100, the client does not enter sleep mode as expected. Both the AP and client exchange TWT request and TWT accept packets; however, after that, the client sends only PS-Poll frames.

Applications Versions: 

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