esptool.py Fatal error when connecting
Posted: Fri Nov 18, 2016 3:30 pmHello,
this is my first topic in this forum. Please excuse if I'm probably not familiar with general usage.
Since some days I started to make some experiments with an ESP 8266 12E.
Unfortunatelly I still have some trouble with this board. Arduino topics are quit new for me as well but I have experencies in Linux even more complicated stuff.
The intention now is to set-up a WifiShield for my Arduino UNO.
For this purpose I bought the mentioned shield which You find for example here:
Since I wasn't able to run the board ontop of my UNO I started to attach it directly to my USB-Serial converter. Like this I was able to use an serial terminal software and I could change the Wifi oder TCP/IP settings.
However, I cannot program the board through the Arduino IDE although there the json file for the ESP was included and additional things where installed.
Also writting binary files using the esptool.py was not successfull.
The error is:
I'm aware that this error message is discussed often in internet but I did not find any solution for me.
I have:
Do You have any hints for me?
Thank You in advance.

Connecting...
A fatal error occurred: Failed to connect to ESP8266I'm aware that this error message is discussed often in internet but I did not find any solution for me.
I have:
- Arduino IDE 1.6.12 with the ESP extensions

Do You have any hints for me?
Thank You in advance.
