El Bruno

Hi !

Another fast post to cover a super important scenario:

Connect to a Wifi network in the Wio Terminal.

The code and implementation are extremely simple for this, and with a couple of lines of code, we can connect and also display the local IP.

Source Code

As usual, the full code is below and some notes

• The Wifi mode must be set to STA and also must be disconnected before starting a new connection.
• I added a counter to display how much time takes to connect to the WiFi network.
• This can also be used for a timeout control.
• I also display the IP address assigned to the device.

	#include "rpcWiFi.h"
	#include <WiFiClientSecure.h>
	#include"TFT_eSPI.h"
	TFT_eSPI tft;
	const char* ssid = "yourNetworkName";
	const char* password = "yourNetworkPassword";
	int connectingSeconds = 0;
	WiFiClientSecure client;
	void setup() {
	tft.begin();
	tft.setRotation(3);
	tft.fillScreen(TFT_BLACK);
	tft.setTextSize(2);
	tft.setCursor(40, 50);
	tft.print("El Bruno – @elbruno");
	tft.setCursor(40, 75);
	tft.print("Connecting to Wi-Fi..");
	// Set WiFi to station mode and disconnect from an AP if it was previously connected
	WiFi.mode(WIFI_STA);
	WiFi.disconnect();
	WiFi.begin(ssid, password);
	// attempt to connect to Wifi network:
	while (WiFi.status() != WL_CONNECTED) {
	connectingSeconds++;
	tft.setCursor(40, 100);
	tft.print("Seconds waiting: ");
	tft.setCursor((40 + tft.textWidth("Seconds waiting: ")), 100);
	tft.print(connectingSeconds);
	// wait 1 second for re-trying
	delay(1000);
	WiFi.begin(ssid, password);
	}
	tft.setCursor(40, 125);
	tft.print("Connected!");
	tft.setCursor(40, 150);
	tft.print("IP: ");
	tft.setCursor((40 + tft.textWidth("IP: ")), 150);
	tft.print(WiFi.localIP());
	}
	void loop() {
	// do nothing
	}

Now we are connected, so we can start to interact with Azure resources !
