  • How to Use ESP32 to Control LED With Blynk Via WiFi

    My code is like this:#define BLYNK_PRINT SwSerial#include <SoftwareSerial.h>SoftwareSerial SwSerial(10, 11); // RX, TX#include <BlynkSimpleStream.h>// You should get Auth Token in the Blynk App.// Go to the Project Settings (nut icon).char auth[] = "6b3f585f3b784db6bb1027f6ef724b56";void setup(){ // Debug console SwSerial.begin(9600); // Blynk will work through Serial // Do not read or write this serial manually in your sketch Serial.begin(9600); Blynk.begin(Serial,auth);}void loop(){; // You can inject your own code or combine it with other sketches. // Check other examples on how to communicate with Blynk. Remember // to avoid delay() function!}

    Hai myboticWhy it shows wasn't online yet on Blynk App? I tried with esp32. I could upload the sketch, but on my mobile wsn't online yet.
