getBlockHeight

Queries the current block height of the Solana cluster. The block height represents the number of blocks that have been produced since the genesis block.

Parameters

Parameter	Type	Description
outBlockHeight	uint64_t&	An output parameter. If the query is successful, this 64-bit unsigned integer will be populated with the current block height.

Return Value

• bool: Returns true if the block height was fetched successfully, false on failure (e.g., network error).

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

// --- WiFi Settings ---

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);

    while (WiFi.status() != WL_CONNECTED) {
        delay(500);
        Serial.print(".");
    }
    Serial.println("\n✅ WiFi connected!");

    Serial.println("\n=== Get Block Height Example ===");

    uint64_t blockHeight = 0;
    if (solana.getBlockHeight(blockHeight)) {
        Serial.print("✅ Current Block Height: ");
        Serial.println((unsigned long)blockHeight);
    } else {
        Serial.println("❌ Failed to get block height.");
    }

void loop() {
