    • M5Stack BASIC - screen turns off when Serial.begin used

      Hi
      I couldn't find solution for my problem anywhere here. I'm playing with CORE + SIM7600 to receive SMS and facing weird problem. Everything works, until I call Serial.begin(9600); in setup(). For example I can upload simple Hello World code and it works just fine. But when I add Serial declaration in code, text shows up for a half of second and screen turns off. I really limited this to minimum and still can't find out what's wrong. Thank you for your help.

      #include <M5Stack.h>

      void setup(){
      M5.begin();
      M5.Power.begin();
      M5.Lcd.print("Hello World");
      Serial.begin(115200);
      }

      void loop() {
      }
