Cant run iperf (wifi) test from "Minized Getting started guide"

tmiller652

Hi There,

 

I've run all the steps in the "minized getting started guide" section 8 "WI-FI" and I can't get the  performance test to run when I issue the command '"perf3 -c 192.168.0.11" from my windows host computer. Note below that I can ping the device, but when I start the iperf server running on the minized and then issue the "iperf3 -c 192.168.0.11" from the windows command line, the error message is "unable to connect to server: Connection refused".  Has anyone seen this behavior or know how to correct it?

 

Best Regards,

Tom MIller

iperf3: error - unable to connect to server: Connection refused

    Just a quick update; I can get the client and server sides of the test to connect now by specifying the port in addition to the address when launching the client:

     

    iperf3 -c 192.168.0.11 -p5001 -t10

     

    But the test still doesn't complete in the specified 10 seconds and only 14 bytes of data are transferred. I can complete the rest of the section 8 steps, including ping various websites and downloading a file via FTP, so it appears as if the WFI is working and I may just move on. But if anyone experiences this same sort of test failure and finds an answer I'd very much appreciate it if you could post a reply here.

    Hi Tom,

     

    Does the Wi-Fi work for other things besides ping?

     

    I haven't tried iperf recently on MiniZed, but I have been using it on Ultra96-V2. I did not specify the port, but the iperf3 reported using Port 5201 on my Ultra96-V2. When I ran the Ultra96-V2 in client mode, I used the following commands:

      Windows  iperf3 -s -i 2 -1

      Ultra96-V2  iperf3 -c <ip address> -i 2 -t 20

     

    Which MiniZed build are you using?
