    CYW43907 iperf throughput?

    NickMckendree_1688136

      What should I be seeing for throughput from iperf and a CYW43907?

       

      Iperf client is on CYW43907 and the server is on PC. The test is over UDP.

      CYW43907 is wireless (5GHz) through router to computer (Ubuntu) over Ethernet.

      The CYW43907 is within 5 feet of the router and the channel appears relatively unused.

      The server is running iperf version 2.0.4+svnr43

      The iperf code in WICED appears to be based on 2.0.5

      Commands:

      iperf -u -c 192.168.1.110 (client)

      iperf -u -s (server)

       

      Test app is based on SDK 6.2
