Connecting LionBit to Wi-Fi Networks

1 min read

To connect your LionBit development board to a Wi-Fi network, you can use the built-in Wi-Fi capabilities provided by the ESP32 microcontroller. Here's a sample code to connect LionBit to a Wi-Fi network using the Arduino IDE:

Wi-Fi Connection Code:

#include <LionBit.h>
#include <WiFi.h>

const char* ssid = "Your_WiFi_SSID";     // Replace with your Wi-Fi network name
const char* password = "Your_WiFi_Password"; // Replace with your Wi-Fi password

void setup() {
  LionBit.begin();

  // Connect to Wi-Fi
  Serial.begin(115200);
  delay(10);

  // Connect to Wi-Fi network
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);

  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("Connected to Wi-Fi");
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  // Your main program logic goes here
}

Instructions: In this code, replace "Your_WiFi_SSID" and "Your_WiFi_Password" with your actual Wi-Fi network name (SSID) and password. When you upload this code to your LionBit, it will connect to the specified Wi-Fi network.

The sample code initializes a Wi-Fi connection and waits until the LionBit successfully connects to the network. You can then proceed with your project logic, such as sending and receiving data over Wi-Fi, interacting with IoT cloud platforms, or accessing web services.
