I read about SPIFF option as a good way, so I installed the tool for sketch data upload in the IDE, which is done.
The problem is that when I try to use this, I get the error message "SPIFFS not Supported on ESP8266".
I have the board defined as NodeMCU 1.0 (ESP 12E Module) as the Lollin site says.
Try IDE 1.8.6, and 1.8.8 with the same answer.
I can not find the solution on the network for this.
In the other hand, I can use other options to get a similar result from my webservers but I would like to resolve this, at least to get the knowhow.
Does anyone have an idea of how to solve this issue?
