Correct… the manual reconnect is more for specific scenarios, so far as I can tell, but doesn’t hurt to have it.
I just thought you were trying to have the serial prints run when not connected to the server… for that you will need the isolate the Blynk.run() command to only process when connected to the server.
@Costas I am still unclear about all these bugs that are supposed to be lurking due the bad core… perhaps you can take a look here… it just keeps running fine… even before connection management I have just added.
