esptool.py -p /dev/tty<SERIALPORT> write_flash 0x00000 0x00000.bin 0x10000 0x10000.bin or with newer versions of esptool (e.g. 0.4.6 on debian): esptool -ca 0x00000 -cf 0x00000.bin -ca 0x10000 -cf 0x10000.bin

How to flash .lua files

For people who enjoy GUIs:
Use ESPlorer tool. Its user friendly and powerful with integrated editor and lots of commands.
Supports NodeMCU and MicroPython.
Needs Java and works on all major PC Plattforms

If you like commandline tools:
Use for example the nodemcu-uploader: nodemcu-uploader -B 115200 upload *.lua

Beware: The tool will not tell you that lines are too long and can not be uploaded but instead throw some error messages you do not understand and exit... The solution is to remove the comments at the beginning of the file before uploading or split them up.

Todo

• Add schematics of current setups for elektrinkkammerl and scannerraum
• Add more doku on how to flash and import the scripts
• Design a breakoutboard with standardized connectors for I-button, and relays
