Re: Increase available flash size for sketch
Posted: Thu Apr 27, 2017 11:30 amMaximum skech size is about 1MB (cache area for CPU), but for OTA to work You need twice memory available - try to use ESP.getSketchSize() and ESP.getFreeSketchSpace() . OTA mechanism is described clearly here https://github.com/esp8266/Arduino/blob ... /readme.md (look for Update process - memory view)
