When using esp_wifi_remote, the compilation reports an error: undefined reference to "esp_netif_create_default_wifi_ap_collect"

When working with the ESP32-P4 development board, integrating the esp_wifi_remote component is crucial for remote Wi-Fi connectivity. However, users have reported encountering an error when using this component, specifically an undefined reference to the esp_netif_create_default_wifi_ap_collect API. This issue has been observed in both ESP-IDF versions 5.4.0 and 5.3.2, making it a pressing concern for developers.

The esp_wifi_remote component is a vital part of the ESP32-P4's Wi-Fi capabilities, enabling remote connectivity and control. However, when integrating this component, users have reported encountering an undefined reference to the esp_netif_create_default_wifi_ap_collect API. This error occurs when the build process fails to locate the required API, resulting in a compilation failure.

To resolve this issue, follow these troubleshooting steps:

1. Check the Issue Tracker

Before proceeding, ensure that this issue is not a duplicate by checking the ESP-IDF issue tracker. This will help you determine if the issue has already been addressed and if there are any known workarounds.
