I've been able to update the ESP firmware successfully, but I can't figure out (or don't understand) how I can update the SPIFFS area using OTA. I tried the Arduino IDE "ESP8266 Sketch Data Upload" tool, but it seems to only talk to the USB COM Port and not to the ESP8266 IP address selection under Port.
Am I missing something obvious or is updating the SPIFFS with OTA and Arduino IDE not possibe?
Thanks for any help.
