工程示例及配置说明
iPerf的配置文件在 components/demos/net/iperf/iperf.c ,支持四种模式：
TCP_SERVER、TCP_CLIENT、UDP_SERVER、UDP_CLIENT
IPERF_REPORT_INTERVAL—————–吞吐测试上报间隔,一般设置为1
IPERF_MAX_TX_RETRY——————–最大重传次数,默认值为10
THREAD_PROIRITY———————–系统优先级,默认设置为4

iPerf Usage
Usage: iperf [-s|-c host] [options]
iperf [-h|--stop]
Client/Server:
-p server port to listen on/connect to
Server specific:
-s run in server mode
Client specific:
-c <host> run in client mode, connecting to <host>
Miscellaneous:
-u udp support, and the default mode is tcp
-h print this message and quit
--stop stop iperf program
iPerf Cmd Example
Client Mode(上行) |
|
TCP Client Mode |
iperf -c IP |
UDP Client Mode |
iperf -c IP -u |
Server Mode(下行) |
|
TCP Server Mode |
iperf -s |
UDP Server Mode |
iperf -s -u |

常见问题
iPerf工具介绍
iPerf测试工具下载: 点击下载 进行下载,使用说明可以参考
iPerf user docs
推荐使用iPerf2.0.x版本
影响iPerf测试吞吐率的因素
DUT Wi-Fi是否进行RF参数校准
DUT天线是否进行调试,OTA测试、EVM测试结果是否正常
测试环境干扰,尽量选择屏蔽箱或者屏蔽房内进行验证
测试环境确认:DUT、AP的距离,使用外置天线还是内置天线等
SDK运行过程中是否有足够的内存
特殊AP的兼容性问题
