Description

Hello Everyone

I want the ESP32 default setting to be HT20.

I changed the settings because I couldn't capture in Wireshark.

Change to HT20 -> HT40+ to capture.

ESP32 Arduino seems to work with HT40+.

Previously, the test condition was Laptop(Station) <-> ESP32(AP).

It worked without any problems, and when I changed the Laptop(station) to an HT20 dedicated device, a data transmission/reception problem occurred.

Is it possible to change ESP32's HT40 setting to HT20 on Arduino?

Sketch

//Server Configuration
    Serial.println("Configuring access point...");
    // You can remove the password parameter if you want the AP to be open.
    WiFi.softAPConfig(local_IP, gateway, subnet);
    WiFi.softAP(Read_SSID, Read_PW);
    IPAddress myIP = WiFi.softAPIP();
    Serial.print("AP IP address: ");
    Serial.println(myIP);
    server.begin();
    server.setNoDelay(true);
    Serial.println("Server started");
    SSID_PW_Change_Flag = 2;
    SSID_PW_Diff_Flag = 2;
    Serial.println("AP START");

esp_wifi docs

#include <WiFi.h>
#include <esp_wifi.h>

void setup() {
  Serial.begin(115200);
  WiFi.softAP("led101010", "test1234");
  esp_wifi_set_bandwidth(WIFI_IF_AP, WIFI_BW_HT20);
}

void loop() {delay(-1);}

is this still valid @CheolsoonKwon?

Might be nice if that were a paramater in the config struct. And perhaps have a setter and getter?
