Set the number of WiFi static RX buffers. Each buffer takes approximately

1.6KB of RAM. The static rx buffers are allocated when esp_wifi_init is

called, they are not freed until esp_wifi_deinit is called.
|
|
|

WiFi hardware use these buffers to receive all 802.11 frames. A higher

|
number may allow higher throughput but increases memory use.

If ESP32_WIFI_AMPDU_RX_ENABLED is enabled, this value is recommended to

help
|
|
Set the number of WiFi dynamic RX buffers, 0 means unlimited RX buffers
|
|
will be allocated (provided sufficient free RAM). The size of each dynamic
|
|
RX buffer depends on the size of the received data frame.
|
|
|
|
For each received data frame, the WiFi driver makes a copy to an RX buffer
|
|
and then delivers it to the high layer TCP/IP stack. The dynamic RX buffer
|
|
is freed after the higher layer has successfully received the data frame.
|
|
|
|
For some applications, WiFi data frames may be received faster than the
|
|
application can process them. In these cases we may run out of memory if
|
|
RX buffer number is unlimited (0). If a dynamic RX buffer limit is set,
|
|
it should be at least the number of static RX buffers.

Select type of WiFi TX buffers:

If "Static" is selected, WiFi TX buffers are allocated when WiFi is
|
|
initialized and released when WiFi is de-initialized. The size of each
|
|
static TX buffer is fixed to about 1.6KB.
|
|
|
|
If "Dynamic" is selected, each WiFi TX buffer is allocated as needed
|
|
when a data frame is delivered to the Wifi driver from the TCP/IP stack.
|
|
The buffer is freed after the data frame has been sent by the WiFi driver.
|
|
The size of each dynamic TX buffer depends on the length of each data
|
|
frame sent by the TCP/IP layer.
|
|
|
|
If PSRAM is enabled, "Static" should be selected to guarantee enough
|
|
WiFi TX buffers. If PSRAM is disabled, "Dynamic" should be selected
|

to improve the utilization of RAM.

For each transmitted data frame from the higher layer TCP/IP stack,
