@ -16,33 +16,34 @@ This example implements the protocol used by the common performance measurement
Performance can be measured between two ESP32s running this example, or between a single ESP32 and a computer running the iPerf tool
Demo steps to test station TCP Tx performance:
1. Configure in `menuconfig` which serial output you are using. Execute `idf.py menuconfig` and go to `Component config/ESP System Settings/Channel for console output`, then select the appropiate interface. By default the UART0 interface is used, this means that for example in the ESP32-S3-DevKitC-1 or ESP32-C6-DevKitC-1 you should connect to the micro-usb connector labeled as UART and not to the one labeled as USB. To use the one labeled as USB you should change the aforementioned setting to `USB Serial/JTAG Controller`.
1. Build the iperf example with sdkconfig.defaults, which contains performance test specific configurations
2. Build the iperf example with sdkconfig.defaults, which contains performance test specific configurations
2. Run the demo as station mode and join the target AP
3. Run the demo as station mode and join the target AP
sta ssid password
3. Run iperf as server on AP side
4. Run iperf as server on AP side
iperf -s -i 3
4. Run iperf as client on ESP32 side
5. Run iperf as client on ESP32 side
iperf -c 192.168.10.42 -i 3 -t 60
The console output, which is printed by station TCP RX throughput test, looks like:
