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 set equal or bigger than ESP32_WIFI_RX_BA_WIN in order to achieve better throughput and compatibility with both stations and APs. config ESP32_WIFI_DYNAMIC_RX_BUFFER_NUM int "Max number of WiFi dynamic RX buffers" range 0 128 if !LWIP_WND_SCALE range 0 1024 if LWIP_WND_SCALE default 32 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. choice ESP32_WIFI_TX_BUFFER prompt "Type of WiFi TX buffers" default ESP32_WIFI_DYNAMIC_TX_BUFFER help 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. config ESP32_WIFI_STATIC_TX_BUFFER bool "Static" config ESP32_WIFI_DYNAMIC_TX_BUFFER bool "Dynamic" depends on !SPIRAM_USE_MALLOC endchoice config ESP32_WIFI_TX_BUFFER_TYPE int default 0 if ESP32_WIFI_STATIC_TX_BUFFER default 1 if ESP32_WIFI_DYNAMIC_TX_BUFFER config ESP32_WIFI_STATIC_TX_BUFFER_NUM int "Max number of WiFi static TX buffers" depends on ESP32_WIFI_STATIC_TX_BUFFER range 1 64 default 16 help Set the number of WiFi static TX buffers. Each buffer takes approximately 1.6KB of RAM. The static RX buffers are allocated when esp_wifi_init() is called, they are not released until esp_wifi_deinit() is called. For each transmitted data frame from the higher layer TCP/IP stack, the WiFi driver makes a copy of it in a TX buffer. For some applications especially UDP applications, the upper layer can deliver frames faster than WiFi layer can transmit. In these cases, we may run out of TX buffers. config ESP32_WIFI_CACHE_TX_BUFFER_NUM int "Max number of WiFi cache TX buffers" depends on (ESP32_SPIRAM_SUPPORT || ESP32S2_SPIRAM_SUPPORT) range 16 128 default 32 help Set the number of WiFi cache TX buffer number. For each TX packet from uplayer, such as LWIP etc, WiFi driver needs to allocate a static TX buffer and makes a copy of uplayer packet. If WiFi driver fails to allocate the static TX buffer, it caches the uplayer packets to a dedicated buffer queue, this option is used to configure the size of the cached TX queue. config ESP32_WIFI_DYNAMIC_TX_BUFFER_NUM int "Max number of WiFi dynamic TX buffers" depends on ESP32_WIFI_DYNAMIC_TX_BUFFER range 1 128 default 32 help Set the number of WiFi dynamic TX buffers. The size of each dynamic TX buffer is not fixed, it depends on the size of each transmitted data frame. For each transmitted frame from the higher layer TCP/IP stack, the WiFi driver makes a copy of it in a TX buffer.

In these cases, we may run out of TX buffers. config ESP32_WIFI_CSI_ENABLED bool "WiFi CSI(Channel State Information)" default n help Select this option to enable CSI(Channel State Information) feature.

However the default length of a beacon frame can simultaneously hold only five root node identifier structures, meaning that a root node conflict of up to five nodes can be detected at one time. In the occurence of more root nodes conflict involving more than five root nodes, the conflict resolution process will detect five of the root nodes, resolve the conflict, and re-detect more root nodes. This process will repeat until all root node conflicts are resolved. However this process can generally take a very long time. To counter this situation, the beacon frame length can be increased such that more root nodes can be detected simultaneously. Each additional root node will require 36 bytes and should be added ontop of the default beacon frame length of 752 bytes. For example, if you want to detect 10 root nodes simultaneously, you need to set the beacon frame length as 932 (752+36*5). Setting a longer beacon length also assists with debugging as the conflicting root nodes can be identified more quickly. config ESP32_WIFI_MGMT_SBUF_NUM int "WiFi mgmt short buffer number" range 6 32 default 32 help Set the number of WiFi management short buffer. config ESP32_WIFI_DEBUG_LOG_ENABLE bool "Enable WiFi debug log" default n help Select this option to enable WiFi debug log choice ESP32_WIFI_DEBUG_LOG_LEVEL depends on ESP32_WIFI_DEBUG_LOG_ENABLE prompt "WiFi debug log level" default ESP32_WIFI_DEBUG_LOG_DEBUG help The WiFi log is divided into the following levels: ERROR,WARNING,INFO,DEBUG,VERBOSE.
