使用iperf测量mesh节点吞吐量问题
使用iperf测量mesh节点吞吐量问题
我把esp-mesh-lite的no-route例程和iperf例程合在一起,想测试两个mesh节点间tcp通信的吞吐量,实际过程中一开始流量正常,数秒后客户端发数据这边monitor卡死没有任何输出,只能手动ctrl+]退出,服务端收数据这边吞吐量归零,正常走完iperf测试时间(我设定的15s)后出现W (897098) iperf: tcp server recv error, error code: 11, reason: No more processes。 客户端那里因为卡死了没输出我也看不了错误原因,我直接使用iperf例程用wifi连接的时候测吞吐量没问题,请问是什么原因呢?用的是esp32-devkitc,esp-idf-v5.2.2
Re: 使用iperf测量mesh节点吞吐量问题
补充下:设置-b 1或-b 2时运行得很平稳,-b 4及以上出现上面说的情况。我想用串口传数据然后用tcp发出去的时候,用460800的波特率没问题,用921600及以上的波特率会出现收不到或者收到但乱码打不开的情况,不知道是不是因为前面测的tcp带宽限制的原因?mesh组网的话吞吐量是只能到2Mb/s吗

更正:不只是mesh上,直接运行iperf例程也有类似问题,有时是卡死,有时是重启,不过都发生在AP这边,重启时错误信息如下:
