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!

    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?
