Programming your ESP8266 OTA
This recipe is going to demonstrate how to upload a sketch to an ESP8266 board over the air. We will upload a simple LED blinking program onto our ESP8266 board using OTA and implement some OTA routines to ensure safety during the upload.
Getting ready
In this recipe, we will need the following components:
