this is appearing in the serial moniter when i press reset button on the esp32 doit devkit

  CloudLight led;

  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
  which are called when their values are changed from the Dashboard.
  These functions are generated with the Thing and added at the end of this sketch.

     Maximum is 4

please don't change anything in my code

my ESP8266 spit some debug data on speed of 73400 baud. if serial monitor is set to 9600 or 115200 then i see such garbage or ?????????????? or [][][][][][][][][][][] .

thank you will try

sollr it dident work the code had no error but still saying
Connection to "TP-Link_2422_5G" failed
Retrying in "4000" milliseconds

Only have seen a baud rate of 74880 with my ESP boards.
Leo..

did you press boot button..?
