Module_test

Unit 1 Blink

LED can change Blink frequency by changing delay time

digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
delay(1000);                       // wait for a second
Serial.println("blink on");
digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
delay(1000);                       // wait for a second

Flash every second

Unit 2 Bluetooth

Phone pairing to connect to Bluetooth

void setup() {
  Serial.begin(115200);
  SerialBT.begin("ESP32test"); //Bluetooth device name
  Serial.println("The device started, now you can pair it with bluetooth!");
  Serial.println("My name is ESP32test");
}

ESP32 Bluetooth name is set by SerialBT.begin()

Uint 3 wifi

wifi_scan

Wifi scan serial port information display can connect wifi name and signal strength

 Serial.begin(115200);

    // Set WiFi to station mode and disconnect from an AP if it was previously connected
    WiFi.mode(WIFI_STA);
    WiFi.disconnect();
    delay(100);

    Serial.println("Setup done")

wifi_web_sever

By connecting to WiFi, you can generate a web page.

const char* ssid = "TP-LINK-";//Please input your wifi ID
const char* password = "123456";//Please input your wifi password

//Log in with a browser to generate a mac address:
//example:192.168.0.108
digitalWrite(led, 1);
server.send(200, "text/plain", "hello from esp32!");
digitalWrite(led, 0);
