Hi,

You could use NCS v2.3.0 shell sample with zperf github.com/.../overlay-zperf.conf, and run "iperf" client on PC to test throughput. To test zperf, it requires iPerf 2.0.5 installed on the host machine. Here is our test:

uart:~$ zperf tcp upload 192.168.32.101 5001 10 1k 1m
Remote port is 5001

Hi Amanda,

Can you share how you tested to reach 12-14Mbps throughput? I was evaluating a Wi-Fi photo transfer project and wanted to test the data rate.

Thanks.

Best regards,
Devin

Hi,

Try these from the shall sample https://github.com/nrfconnect/sdk-nrf/blob/main/samples/wifi/shell/overlay-zperf.conf

We got 12-14 Mbps.
