## Project：wifi iperf project

## Application：
# Armino Wi-Fi IPERF example

## Introduction
This example implements the protocol used by the common performance measurement tool [iPerf]
Performance can be measured between two BKKEN 7256/7235/7258/7236 running this example, or between a single BKKEN 7256/7235/7258/7236 and a computer running the iPerf tool

3. Run the demo as station mode and join the target AP
   sta ssid password

4. Run iperf as server on AP side
   iperf -s -i1

5. Run iperf as client on bk7256 side
   iperf -c 192.168.0.1 -i -t60

The console output, which is printed by station TCP RX throughput test, looks like:
cmd: ap bk_test
cmd: sta bk_test

 netif(sta) ip4=192.168.0.100 mask=255.255.255.0 gate=192.168.0.1 dns=192.168.0.1

>iperf> iperf -s -i -t1000
iperf: new client connected from (192.168.0.100, 61285)

[0-1] sec bandwidth: 15865 Kbits/sec.

[1-2] sec bandwidth: 17908 Kbits/sec.

[2-3] sec bandwidth: 17434 Kbits/sec.

[3-4] sec bandwidth: 18688 Kbits/sec.

[4-5] sec bandwidth: 18765 Kbits/sec.

[5-6] sec bandwidth: 21490 Kbits/sec.

[6-7] sec bandwidth: 21765 Kbits/sec.

[7-8] sec bandwidth: 21095 Kbits/sec.

[8-9] sec bandwidth: 20800 Kbits/sec.

Steps to test station/soft-AP TCP/UDP RX/TX throughput are similar as test steps in station TCP TX.
