fl::net::OTA Class Reference

Detailed Description

OTA (Over-The-Air) update manager for ESP32 platforms.

Provides a unified interface for enabling OTA firmware updates via Arduino IDE (port 3232) and web browser (HTTP POST at "/"). Handles network setup (Wi-Fi), mDNS registration, and authentication automatically.

Public Types
using	ErrorCallback = fl::function<void(const char* message)>
	Callback function type for OTA errors.
using	ProgressCallback = fl::function<void(size_t written, size_t total)>
	Callback function type for OTA progress updates.
using	StateCallback = fl::function<void(u8 state)>
	Callback function type for OTA state changes.

Public Member Functions
	OTA () FL_NOEXCEPT
	Default constructor (lazy initialization)
	~OTA () FL_NOEXCEPT
	Destructor - cleans up resources.
bool	begin (const char *hostname, const char *password)
	Start OTA services only (network already configured)
bool	beginWiFi (const char *hostname, const char *password, const char *ssid, const char *wifi_pass)
	Start OTA with full Wi-Fi setup (station mode)
bool	enableApFallback (const char *ap_ssid, const char *ap_pass=nullptr)
	Enable AP (Access Point) fallback mode if Wi-Fi STA connection fails.
u8	getFailedServices () const
	Get bitmask of services that failed to initialize.
bool	isConnected () const
	Check if WiFi is connected.
void	onBeforeReboot (void(*callback)())
	Set callback to be called before device reboots after OTA update.
void	onError (ErrorCallback callback)
	Set error callback (called on OTA errors)
void	onProgress (ProgressCallback callback)
	Set progress callback (called during firmware upload)
void	onState (StateCallback callback)
	Set state callback (called on state transitions)
void	poll ()
