twt setup: wrong parameter count

[ChengQing Zhao]

I want to use the example of "Wi Fi: Shell" to set TWT parameters by referring to the official documentation：

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/wifi/station_mode/powersave.html

and blogs:

 https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/target-wake-time-on-the-nrf7002-dk 

i set the command such as :

wifi twt setup 0 0 1 1 0 1 1 1 65000 524000

OR

wifi twt setup 0 0 2 2 0 1 1 1 20 60000

but  it is print "setup: wrong parameter count", as shown in log :

so, can you give me some help, thank you very much!

Hi,

 

In order to add zperf to the wifi/shell sample, you need to append the "overlay-zperf.conf" to your sample.

uart:~$ > twt
twt
twt: command not found

Which example is this based on? The command should be "wifi twt" if you are using the wifi/shell.

 

Have you had a look at the twt sample? it includes a way to generate traffic to the device:

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/wifi/twt/README.html

 

Kind regards,

Håkon

Thank you  Håkon Alseth, Wi-Fi:Shell example is seem already include "overlay-zperf.conf", as shown in the picture.

Yes, that is my question, i am sorry. thank you for your guidance

Yes, twt example seem to give another way, but it can not set DTIM mode, i want  to compare the throughput under DTIM and TWT, so, i think zperf is more simple and flexible.

Hi,

 

Click button "Add extra fragment" - then select the file "overlay-zperf.conf", and click "OK".

It should then look like this:

DTIM is enabled by default. The nrf7002 will follow what is set by the access point.

 

Kind regards,
