ESP8266 Community Forum

- Sun Oct 30, 2016 7:49 pm #57413 I'm building a Neopixel clock and want to be able to download the exicutable later if the hardware (ESP8266 12-E) fails in the future.

I have built some projects in the past and although they worked under the then current compiler and library levels, when I try to recompile them with the now current and updated compiler and libraries.. NO WORK!

I need a way to save the executable then download it later without having to recompile ( and screw it up) later.

Any advise would be appreciated.

Arduino IDE 1.6.11

- Mon Oct 31, 2016 8:52 am #57437 When compiling a sketch in Arduino, the resulting binary is in a temporarly folder, for example un Linux, it would be something like /tmp/build8242249818430550825.tmp where the MySketch.cpp.bin binary will be located.
You can simply copy it elsewhere, and upload it later using esptool or esptool.py

Martin --Thanks, I was able to locate the build file (quite a few internal files under that folder). I'll see where I can find out how to find and use the tools you mentioned.
