BLYNK_WRITE_DEFAULT() called as Interrrupt?

Need Help With My Project

Hi,
one principle question: when will BLYNK_WRITE_DEFAULT() or BLINK_WRITE (…) be executed ?
will it interrupt the running program at any step if a new event is happening or when Blynk.Run() is called in the main loop?
Thanks
Klaus

When Blynk.run() is executed (which normally happens in the void loop, but you can call it at other times too) then the device asks the server if it has any new info for it.
If the server replies that one or more virtual datastream values have changed the the corresponding BLYNK_WRITE callback functions will be executed.

Pete.
