Get text from nextion into arduino variable

Hi All,


I am trying get text from nextion into arduino variable but its not working I tried the following:


  memset(buffer, 0, sizeof(buffer)); //

  b211.getText(buffer, sizeof(buffer)); //

  Serial.println(buffer);


and it only works if i set text manually using tState2.setText("Example"); and call the above again


I have also tried this arduino code but same problem:

 char text_char[4];

 tState2.getText(text_char, 4);

 Serial.println(text_char);


All I get is empty output in serial monitor expect if i manually do  tState2.setText("example"); . I dont want this i want to get the text from live nextion screen. I have been stuck for a week on this :


Any help would be apprecited
