The sketch uses the WiFi.setPersistent() setting. After the connection is successful, it is remembered by the ESP and set for autoconnect at start. Other sketches don't need to call WiFi.begin(), only wait until WiFi.status() returns WL_CONNECTED. Note: The ESP SDK remembers the SSID ...

Hello, I'm having an issue with uploading to the Uno R4 WiFi in a Windows environment. This all uses ArduinoCore-renesas v1.0.1. When in the Arduino IDE, the device is recognized. It's only when uploading to it that it fails to find the ...
The status codes for WiFi.status() are not well documents, but I did fine this in a forum….. Serial.println(WiFi.status()); // WL_NO_SHIELD = 255, // for compatibility with WiFi Shield library // WL_IDLE_STATUS = 0, // WL_NO_SSID_AVAIL = 1, // WL_SCAN_COMPLETED = 2, ...
WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(1000); Serial.println("Connecting to WiFi.."); } Serial.println("Connected to the WiFi network"); } void loop() { if ((WiFi.status() == WL_CONNECTED)) { //Check the current connection status ...
Arduino codes publishes data to the MQTT topicarduino-001/send,Subscriber Windowon PC subscribe that topic to receive the data. Open the Serial Monitor, you will see Arduino periodically publish a message to a topic. COM6 Send IP Address: 192.168.0.2 Arduino - Connecting to MQTT broker Arduino...
, you do not need to control an LED, you can use the same methods to do almost anything that is controlled in the same way. For example, I use similar techniques when setting up remote controls using Bluetooth and wifi connections and instead of setting a pin state I send control codes...
