Description of Issue

When using Arduino IDE 1.8.19, the code compiles and functions as expected. However, when using Arduino IDE 2.3.2, I encounter the following error:

please provide minimal sketch to reproduce. This is not expected

I am unsure which part of the code is causing this issue. Due to the company's NDA policy, I cannot share any code.

For reference, I can mention that the library was written for ESP-IDF v5.2.2. I used the same header files when making the library compatible with the Arduino IDE.

@kunal-nezai How should anyone help, without a piece of an example! code?
No one says you should provide code which is under NDA.

[me-no-dev]

@kunal-nezai you are using some IDF code in the place of Arduino code. Maybe custom WiFi handling or something of the sort to get this message. You can copy the function from here to your codebase and get to compile.

@me-no-dev Hello!

Today, while working, I noticed that the older version of Arduino IDE (1.8.19) uses version 3.0.2 of the ESP32 board, whereas the new Arduino IDE (2.3.2) uses version 3.0.3 of the ESP32 board.

To test my suspicion, I installed version 3.0.2 of the ESP32 board in the new Arduino IDE, and it is now functioning properly.

I suspect there is something in version 3.0.3 that is causing the issue.

[me-no-dev]

@kunal-nezai it's the fact that you do not use Arduino fully, but instead manage WiFi through the IDF API only. If your network stack was using Arduino's APIs, this would not have happened. Adding the code above will make it work for the future, Else you will be stuck on 3.0.2

I have the same issue. Here is a test case

#include "esp_netif.h"

#define STATIC_IP_ADDR "10.0.0.2"
#define DEFAULT_GATEWAY "10.0.0.1"
#define DEFAULT_NETMASK "255.255.255.0"


void setup() {
  ip4_addr_t ip;
  ip4_addr_t gw;
  ip4_addr_t netmask;
  ip4addr_aton(STATIC_IP_ADDR, &ip);
  ip4addr_aton((const char *)DEFAULT_GATEWAY, &gw);
  ip4addr_aton((const char *)DEFAULT_NETMASK, &netmask);

  esp_netif_ip_info_t ip_info;
  memset(&ip_info, 0, sizeof(esp_netif_ip_info_t));
  ip_info.ip.addr = ip.addr;
  ip_info.gw.addr = gw.addr;
  ip_info.netmask.addr = netmask.addr;

  uint8_t lwip_addr[6] = { 0x02, 0x02, 0x11, 0x22, 0x33, 0x02 };

  esp_netif_inherent_config_t base_cfg = {
    .flags = (esp_netif_flags_t)(ESP_NETIF_DHCP_SERVER | ESP_NETIF_FLAG_EVENT_IP_MODIFIED | ESP_NETIF_FLAG_AUTOUP),
    .ip_info = &ip_info,
    .get_ip_event = IP_EVENT_ETH_GOT_IP,
    .lost_ip_event = IP_EVENT_ETH_LOST_IP,
    .if_key = "usb_eth",
    .if_desc = "usb ncm config device",
    .route_prio = 10
  };

  esp_netif_driver_ifconfig_t driver_cfg = {
    .handle = (void *)1,
    .transmit = NULL, // just for this example
    .driver_free_rx_buffer = NULL // just for this example
  };

  esp_netif_config_t cfg = {
    .base = &base_cfg,
    .driver = &driver_cfg,
    .stack = ESP_NETIF_NETSTACK_DEFAULT_ETH,  // USB-NCM is an Ethernet netif from lwip perspective, we already have IO definitions for that:
  };
}

void loop() {
  // put your main code here, to run repeatedly:

}

Using .stack = ESP_NETIF_NETSTACK_DEFAULT_ETH or any of the other stacks results in a linker error

The same code compiles fine on a non-Arduino 3 SDK.

Interestingly this code compiles fine with platformio

Interestingly this code compiles fine with platformio

I doubt that. Probably not using the same Arduino core code base and libs.

[i-am-shodan]

platform = https://github.com/platformio/platform-espressif32.git
platform_packages = 
	platformio/framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#3.0.3
	platformio/framework-arduinoespressif32-libs @ https://github.com/espressif/esp32-arduino-libs.git#idf-release/v5.1

I'm running it right now

[Jason2866]

As said not using same code base. This https://github.com/espressif/arduino-esp32.git#3.0.3 uses Arduino commit of release Core 3.0.3
The change in Arduino was done after
To use all latest use this
