I've been search for a way to upload "settings.h" to an ESP8266 with having to flash the chip.
I have found where we can Post files to SPIFF but have yet to find how I can POST a file to where it can be used as an "include" file in the Sketch.
I tried #include </data/settings.h> but that yields an error.
The idea is that in operation the chip will be physically installed in a place that is hard to get at. In order to update the chip with configuration settings for ht e application, I put all those settings in an Include file.
What I want to do is to replace the Include file (Setting.h) using a call to the ESP8266.
I was following this but I could not figure out how to get the file to anyplace but in /data inthe SPIFF:
