I don't think you can wireless upload sketches to the Arduino using a ESP-01.I would like to be proven wrong.
And i need something more detailed than use this firmware :S Any for dummies tutorial just to add wireless to an arduino to upload sketches will be great.
Depending on your project you may be even better off by replacing the whole Arduino by an ESP8266 based board, like the NodeMCU or WeMOS mini.
@wvmarle , yes i mentioned it and i have a thread about it. But i dont want that thread to influence this one.
So now you know why we want all info about a project in a single thread. I don't think I read that thread, so didn't know this, and as a result you got useless advice. That's a waste of time. It's the same project, so of course things WILL influence one another.
What do i have to upload an sketch to the Arduino using wireless.
