4.10.60 I'm scanning Wi-Fi on an ESP32 device using release/v3.3 version of ESP-IDF. When
there are some identical SSIDs, same SSID names will show in the Wi-Fi list repeatedly.
Is there an API to filter such repeated names?
4.10.61 Does ESP8266 support EDCF (AC) scheme?
4.10.62 I'm using the master version of ESP8266-RTOS-SDK to open the WiFi Qos application
to get EDCF support. How does ESP8266 decide which data packet should be allocated to
the EDCF AC category?
4.10.63 Using ESP32, how to configure the maximum Wi-Fi transmission speed and stability with-
out considering memory and power consumption?

4.10.65 How to get CSI data when using ESP32 device in Station mode?
4.10.66 In AP + STA mode, after an ESP32 is connected to Wi-Fi, will the Wi-Fi connection be
affected if I enable or disable its AP mode?
4.10.67 I'm using ESP-IDF release/v3.3 for ESP32 development, but only bluetooth function is
needed, how to disable Wi-Fi function through software?
4.10.68 In ESP-IDF, the esp_wifi_80211_tx() interface can only be used to send data pack-
ets, is there a corresponding function to receive packets?
4.10.69 What are the reasons for the high failure rate of esptouch networking?

4.10.72 What is the maximum length of Wi-Fi MTU for an ESP32 and how to change it?
4.10.73 During the on-hook test for an ESP32 device, the following log shows. What does it mean?
4.10.74 How to disable AP mode when ESP32 is in AP + STA mode?
4.10.75 After ESP32 used the Wi-Fi function, are all ADC2 channels unavailable?
4.10.76 How do I set the country code for a Wi-Fi module ?
4.10.77 When using ESP32 as a SoftAP and have it connected to an Iphone, a warning prompts
as "low security WPA/WPA2(TKIP) is not secure. If this is your wireless LAN, please
configure the router to use WPA2(AES) or WPA3 security type", how to solve it?
4.10.78 Since ESP32' s Wi-Fi module only supports 2.4 GHz of bandwidth, can Wi-Fi networking
succeed when using a multi-frequency router with both 2.4 GHz and 5 GHz of
4.10.79 How to obtain the RSSI of the station connected when ESP32 is used in AP mode?
4.10.80 Does ESP32 support FTM(Fine Timing Measurement)?

4.10.83 Is there a standard for the number of Wi-Fi signal frames?
4.10.84 What is the current progress of WFA bugs fixing?
4.10.85 When Wi-Fi connection failed, what does the error code mean?
4.10.86 When using ESP32's Release/v3.3 of SDK to download the Station example, the device
cannot be connected to an unencrypted Wi-Fi. What is the reason?
4.10.87 What is the maximum PHY rate of Wi-Fi communication of ESP32-S2 chip?
4.10.88 Does ESP modules support EAP-FAST?
4.10.89 Does ESP modules support the WiFi NAN (Neighbor Awareness Networking) protocol?
4.10.90 When using ESP32 with release/v3.3 version of ESP-IDF. When configuring the router, is
there an API to directly tell that the entered password is wrong?
4.10.91 When testing the Station example of ESP32 base on v4.4 version of ESP-IDF, how to
support WPA3 encryption mode?
4.10.92 How does ESP32 speed up the Wi-Fi connection?

client certificates?
4.10.95 Does ESP8089 support Wi-Fi Direct mode?
4.10.96 How does ESP32 connect to an AP whose RSSI does not fall below the configured threshold
when there are multiple APs in the environment?
4.10.97 ESP32 Wi-Fi has a beacon lost and sends 5 probe requests to the AP after 6 seconds. If
the AP does not respond, disconnection will be caused. Can this 6 seconds be configured?
4.10.98 Does ESP32 Wi-Fi work with PSRAM?
