Self-updating ( from WEB server HTTP ) OTA firmware for ESP8266


#41

That is your problem. Needs to be < 50%.

Which MCU are you using?


#42

@iBK: ESP12E


#43

In board settings you should be able to increase flash size to 1MB.


#44

@IBK: That is means flash size 4MB(1MB SPIFFS) right.


#45

Yes, but it will only give 1MB max sketch size. You should then be good to go.
