This Christmas, I added a whole bunch of lights powered by 5V power sources. My goal was to switch them on at sunset, and switch them off on sunrise, by using a MOSFET for power control :)
While I was doing this, I wanted to send OTA updates of my Lua files to the ESP8266 via WiFi. For some unknown reason, I couldn’t use luatool.py’s TCP update method.
So, I ended up building my very own OTA update protocol (which turned out to be fun!). To begin, add
ota.lua to your project, and invoke it using
dofile("ota.lua") in your
Then, to use this shiny new TCP endpoint created on your ESP8266/NodeMCU, create a wrapper shell script:
Heads up! Replace
HOST with the IP of your NodeMCU.
The wrapper script will automatically trigger a restart at the end. To use the wrapper script:
$ chmod +x ota.sh $ ./ota.sh file1.lua file2.lua init.lua
And that’s it! OTA update away!
