help for making script ota

hi i want some help to make this script update ota i tried the example with no results .
can you help me - guide me through ? this is the original code
any help will be greatly appreciated
thanks in advance

Full instructions on how to set up OTA with example code (and a lot more interesting information about how to deal with the ESP8266 processor) you can find in Pieter's starter guide. OTA is in chapter 10.


Oh... A ] got lost :slight_smile: Fixed.
