getEpochInfo

Queries the Solana cluster for information about the current epoch. An epoch is a period of time on the network defined by a certain number of slots. This function provides detailed data about the network's current state and timing.

The EpochInfo Structure

The function populates a pointer to the following C++ structure:

Parameters

Parameter	Type	Description
outEpochInfo	EpochInfo&	An output parameter. This is a reference to an EpochInfo struct that will be populated with the current epoch data upon successful execution.

Return Value

• bool: Returns true if the epoch information was fetched successfully, false otherwise.

Example Code (main.cpp)

#include <Arduino.h>
#include <WiFi.h>
#include "Infratic-lib.h"

// --- WiFi Settings ---
const char* WIFI_SSID = "YOUR_WIFI_SSID";
const char* WIFI_PASSWORD = "YOUR_WIFI_PASSWORD";

// --- Solana Settings ---
const String SOLANA_RPC_URL = "[https://api.devnet.solana.com](https://api.devnet.solana.com)";
Infratic solana(SOLANA_RPC_URL);

void setup() {
    Serial.begin(115200);
    delay(1000);

    // Connect to WiFi
    Serial.print("Connecting to WiFi...");
    WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
    while (WiFi.status() != WL_CONNECTED) {
        delay(500);
        Serial.print(".");
    }
    Serial.println("\n✅ WiFi connected!");

    Serial.println("\n=== Get Epoch Info Example ===");

    EpochInfo currentEpoch;
    if (solana.getEpochInfo(currentEpoch)) {
        Serial.println("✅ Epoch Info Received Successfully:");
        Serial.printf("   -> Absolute Slot: %llu\n", currentEpoch.absoluteSlot);
        Serial.printf("   -> Block Height : %llu\n", currentEpoch.blockHeight);
        Serial.printf("   -> Epoch        : %llu\n", currentEpoch.epoch);
        Serial.printf("   -> Slot Index   : %llu\n", currentEpoch.slotIndex);
        Serial.printf("   -> Slots/Epoch  : %llu\n", currentEpoch.slotsInEpoch);
    } else {
        Serial.println("❌ Failed to get epoch info.");
    }
}

void loop() {
    // This example runs once in setup.
