Hello @tavdog, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
Summary of Changes
This pull request integrates the esp32-wifi-manager component, which provides a web portal for easy management of WiFi networks on ESP32 devices. It includes the component itself, an example, and necessary configuration files. The wifi manager allows the ESP32 to automatically connect to previously saved networks or start its own access point for configuration.
Highlights
- Integration of esp32-wifi-manager: The core functionality of this PR is the addition of the esp32-wifi-manager component, enabling WiFi network management via a web interface.
- Configuration Options: Introduces Kconfig options for customizing the WiFi manager, such as access point SSID, password, and various timers.
- Example Implementation: Includes a default demo example showcasing the usage of the WiFi manager in a project.
- HTTP Server Integration: The wifi manager spawns its own http server, and it is possible to extend this server to serve custom pages in the application.

Code Review
This pull request integrates the WiFiManager component, enhancing the device's WiFi connectivity management. The changes include adding new files for the component, updating build configurations, and modifying the main application to use the WiFiManager. Overall, the integration seems well-structured, but there are a few areas that could benefit from further review and potential adjustments.
Summary of Findings
- Missing License Headers: Several new files lack the standard license header. It's important to include the license information in every file for legal clarity and compliance.
- Hardcoded Credentials: The code attempts to connect with hardcoded WiFi credentials. While this can be useful for initial setup, it's crucial to ensure that these credentials are not exposed in production builds and that a mechanism exists for users to configure their own credentials.
- Potential Deadlock: The code uses a semaphore to protect access to the JSON buffer. However, there's a potential deadlock if the WiFiManager task and the HTTP server task both try to acquire the semaphore simultaneously and become blocked.
Merge Readiness
The pull request introduces significant functionality by integrating the WiFiManager. However, the missing license headers and potential deadlock issues need to be addressed before merging. Additionally, the use of hardcoded credentials should be carefully reviewed to ensure security best practices are followed. I recommend that this pull request not be merged until these issues are resolved. I am unable to directly approve this pull request, and users should have others review and approve this code before merging.

Consider adding a check to ensure pvParameter is not NULL before dereferencing it. This can prevent potential crashes if the callback is invoked with a NULL parameter.
void cb_connection_ok(void* pvParameter) {
if (pvParameter == NULL) {
ESP_LOGE(TAG, "pvParameter is NULL");
return; // Exit the function to avoid dereferencing a NULL pointer
}
