OTA::start_OTA_threads

Description

To begin threading tasks for OTA firmware update. Supports both HTTP and HTTPS connections.

Syntax

// HTTP mode (plain TCP, no encryption)
void start_OTA_threads(int port, char* server);
void start_OTA_threads(int port, char* server, WiFiClass &ota_wifi);

// HTTPS mode (TLS encrypted)
void start_OTA_threads(int port, char* server, bool useSSL);
void start_OTA_threads(int port, char* server, WiFiClass &ota_wifi, bool useSSL);

Parameters

port: port number for the OTA server (e.g., 3000 for HTTP, 443 for HTTPS)

*server: pointer for OTA server IP address

useSSL: set to true to enable TLS/SSL (HTTPS), false for plain HTTP

ota_wifi: reference to a WiFiClass instance (optional; defaults to WiFi)

Returns

NA

Example Code

Example: OTA

// HTTP
ota.start_OTA_threads(3000, "192.168.1.100");

// HTTPS
ota.start_OTA_threads(443, "192.168.1.100", true);

Note

“OTA.h” must be included to use the function. When using HTTPS, ensure the server has a valid certificate (run setup-https.sh in the ameba-OTA-UI directory).
