That is part of the Over The Air update option for ESP (basicly uploding your sketch over the WiFi network instead of plugging it into USB) - see here for example C++ Blynk (Legacy) - Code Examples for Basic Tasks - #2 by Gunner Nothing to do with Timers 
Thanks again @Gunner I realize that I don’t need to code this in my case, 'cos I using ethernet shield 
I’ll try to use this code to my project and see if it’s work for me.
This is my code, but still have issues, please help me!!!

Works fine for a time, then wen the advanced input timmer run out it crash everything and lost conection.
