Wi-Fi Throughput when device is in AP mode?

Ziyao Zhou

Hi

I noticed nordic provides Wi-Fi: Throughput to evaluate the throughput when device is working in STA mode.

 

If I want to evaluate the device in AP mode, is there any samples?

Thanks!

    Ah sorry I guess I overlooked the throughput part of your question. No, I guess this sample doesn't have an easy way to allow for that. 

    You could try to modify the sample and add features from the throughput sample. Though I'll ask the relevant R&D team if they have any other suggestions. I'll get back to you once I hear from them - presumably next week.

    Regards and have a good week-end,

    Hi again,

    So you can use the throughput sample for measuring the AP mode throughputs as well - just use the DK in SoftAP mode and use zperf shell command in the place of iperf (used with the COTS AP + connected PC). 

    Regards,

    Hi

    Could you give me more details? How could we use the DK in AP mode? Does it simply turn on  CONFIG_NRF70_AP_MODE = y in the project config?
