Work in Progress
Hardware
8266 can be programmed as every other arduino or in lua langage if you have the right firmware.
- There is plenty of ESP8266 boards available.
- The "ready made", brain free ones are devboard like nodemcu or wemos D1 mini. Their extra button put the thing in program mode.
- it's 3.3 V board.
- it's 3.3 V board.
- it's 3.3 V board.
- It won't work and you may damage it if you connect stuff that is running under 5V
- It's a tiny board, with almost no memory, nice at home, but if you want reliable internet behavior, send the data to a real server.
Software
- Basically there is 2 main firmware paradigms Arduino/Lua
- How to talk ? You can use a terminal i.e : screen /dev/tty.USB0 9600
- Esplorer is great but use java.
- 9600 is classical for nodemcu.
- 115200 is classical for Wemos D1 mini
Arduino
- you want speed, realtime or love arduino
- get the ESP8266 library for arduino and program the thing as usual.
Lua
- you prefer the easy path : get one with lua firmware or upload it !
- luatool is in python and just works with a lua firmware. Download source. You need pyserial : sudo easy_install pyserial
- to flash the thing it's esptool : tutorial
- lua firmware can be found
