AP Configuration Fails after updating from 3.0.1 to 3.0.2 and Later

[Bolbolito]

Board

Lolin ESP32 S2 Mini

Device Description

None

Hardware Configuration

Not Applicable

Version

v3.0.4

IDE Name

Arduino IDE

Operating System

Windows 11

Flash frequency

40Mhz

PSRAM enabled

yes

Upload speed

115200

Description

If updated to 3.0.2 the AP cannot be configured it just returns the old or default settings when calling the initializeOTA() function in my code and logs shows that AP cannot be configured. Works fine with 3.0.1.

Sketch

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

oid setup() {
  Serial.begin(115200);

  setCpuFrequencyMhz(80);

  WiFi.mode(WIFI_STA);
  WiFi.disconnect();
  esp_wifi_set_protocol(WIFI_IF_STA, WIFI_PROTOCOL_LR);

  delay(1000);

  initESPNow();
}

void initializeOTA() {
  isUpdating = true;
  esp_now_deinit();
  delay(1000);

  String macAddress = WiFi.macAddress();
  macAddress.replace(":", "");  // Remove colons from MAC address

  // Define the SSID using the full MAC address
  String ssid = macAddress;

  // Define the password using the first 5 characters of the MAC address
  String password = "TEST-" + macAddress.substring(0, 5);

  // Print the SSID and password to the serial monitor
  Serial.print("SSID: ");
  Serial.println(ssid);
  Serial.print("Password: ");
  Serial.println(password);

  esp_wifi_set_protocol(WIFI_IF_STA, WIFI_PROTOCOL_11B | WIFI_PROTOCOL_11G | WIFI_PROTOCOL_11N);

  WiFi.mode(WIFI_AP);
  
  esp_wifi_set_protocol(WIFI_IF_AP, WIFI_PROTOCOL_11B | WIFI_PROTOCOL_11G | WIFI_PROTOCOL_11N);

  // Initialize the WiFi in AP mode with the custom SSID and password
  WiFi.softAP(ssid.c_str(), password.c_str());

  // Configure the static IP address
  if (!WiFi.softAPConfig(local_IP, gateway, subnet)) {
    Serial.println("Failed to configure AP");
  }

  // Print the IP address of the AP
  Serial.print("AP IP address: ");
  Serial.println(WiFi.softAPIP());
}

Debug Message

16:10:57.763 -> SSID: XXXXXXXXXXXX
16:10:57.763 -> Password: XXXXX-XXXXXX
16:10:58.767 -> Failed to configure AP
16:10:59.756 -> AP IP address: 192.168.4.1

Other Steps to Reproduce

Compiled using my two other pc with the same result when version is 3.0.2 or later.

I have checked existing issues, online documentation and the Troubleshooting Guide

the code above does not compile, please fix it. You are mixing IDF and Arduino calls. It's not rally clear what you are trying to do.

Edit: This is the part of my code for initialization of the AP. I am trying to initialize the AP for my OTA update page. But it does not work anymore for 3.0.2 and later. I can't set the SSID, password, and ip address. It works fine without switching to LR mode and not using esp-now. It only has a problem when using esp-now and LR mode. Adding delays when setting the AP made no difference.

#include <WiFi.h>
#include <esp_now.h>

bool isUpdating = false;

void initESPNow() {
  if (esp_now_init() != ESP_OK) {
    Serial.println("Error initializing ESP-NOW");
    return;
  }
}

void setup() {
  Serial.begin(115200);

  WiFi.mode(WIFI_STA);
  WiFi.disconnect();
  esp_wifi_set_max_tx_power(44);
  esp_wifi_set_protocol(WIFI_IF_STA, WIFI_PROTOCOL_LR);

  delay(1000);

  initESPNow();
  delay(1000);
  initializeOTA();
}

void loop() {
  //

  // Configure the static IP address

with the sketch above, AP starts normally on my end. Here is the debug log:

Thank you. I have found the cause of the problem and fixed it by moving the initializeOTA calling to the loop. For some reason on 3.0.2 and later you can't trigger the initializeOTA directly via the onDataRecv function for esp-now anymore.

My old code:
void onDataRecv(const esp_now_recv_info *info, const uint8_t *incomingData,
                int len) {
  if (len >= 4 && memcmp(incomingData, "otaupdate", 9) == 0) {
    initializeOTA();
  }
}
