I want to update software on multiple of my esp8266 devices that are currently sending data to my firebase database. I found this tutorial (Over-the-Air Arduino firmware updates using Firebase, Part 1 | by Matt Welsh | Firebase Developers | Medium) for ESP32 and tried adapting it to work with ESP8266 however it writes no binary and "gives up". I am lost as too where to even find the solution.
I have attached part of my code below and the output I get in serial monitor. I am able to connect to wifi and send data to firebase.
