CONFIG_ESP32_WIFI_RX_BA_WIN

WiFi AMPDU RX BA window size

Type: int

Help

Set the size of WiFi Block Ack RX window. Generally a bigger value means
higher throughput and better compatibility but more memory. Most of time
we should NOT change the default value unless special reason,
e.g. test the maximum UDP RX throughput with iperf etc. For iperf test in
shieldbox, the recommended value is 9~12. If PSRAM is used and WiFi memory
is preferred to allocat in PSRAM first, the default and minimum value
should be 16 to achieve better throughput and compatibility with both
stations and APs.
