Matter on TWT

[Martin Hauser]

Hi

I am trying to test Wi-Fi 6 Target Wake Time (TWT) in a matter device. I have built and run the light bulb example, but I can't seem to find a way to make it run with TWT. Is there a way to configure the sample to use TWT?

[Martin Hauser]

yes

Hi, 

Does it have nRF board files under nrf\boards\arm and zephyr\boards\arm?

From the support information and setting figures, everything looks correct. I don't know why it cannot load the board for the build config. Does it also happen to the formal version like v2.4.1? Try to reopen the VSCode or PC to see if that can help or not.

Hi

Both nrf\boards\arm and zephyr\boards\arm have boards. 

I have no problem with V2.4.1 (installed from nRF Connect for Desktop)

I have also tried to restart both VSCode and my PC, and also tried to reinstall the SDK version 2.4.99

Hi again

After reinstalling a second time I got it to work.

Now when I try to set up TWT as in the sample you provided in the Matter template sample I get the error -8 ("TWT setup failed: -8" in the console). I can't seem to find what the error means.

hope you can help.

Hi, 

According to ncs\toolchains\31f4403e35\opt\zephyr-sdk\arm-zephyr-eabi\arm-zephyr-eabi\sys-include\sys\errno.h, 

-8 means Exec format error. If the error code is returned by net_mgmt, you can take a look at the function definition https://github.com/nrfconnect/sdk-zephyr/blob/main/include/zephyr/net/net_mgmt.h#L77-L93 and check the format.
