Rewrite whole project as a Arduino IDE project
The lua flashing never really worked and I had so many problems flashing the hardware. The Arduino IDE does it much better so this is now written in thes Arduino language which looks like C++. Still need to explain the hardware setup.

It expects a credentials.lua file with content like this:
|
Open the esptmp.ino file in the Arduino IDE.
|
||||||
|
|
||||||
SSID = "myssid"
|
It expects the credentials for your WiFi in the file like this:
|
||||||
PASSWORD = "mypasswd"
|
|
||||||
|
|
||||||
Copy the credentials.lua.example file into credentials.lua and change
|
const char* ssid = "myssid";
|
||||||
it so et matches your wifi credentials.
|
const char* password = "mypass";
|
||||||
|
|
||||||
|
Change the credentials in esptmp.ino so it matches your wifi credentials.

To put the code onto the ESP8266 you need the luatool which is
|
1. Under File -> Preferences set as Additional Boards Manager URLs:
|
||||||
included as a git submodule.
|
http://arduino.esp8266.com/versions/2.3.0/package_esp8266com_index.json
|
||||||
|
2. Chose under Tools -> Board the "Node MCU 1.0 (ESP12-E Module)"
|
||||||
|
3. Press the Upload button
|
||||||
|
|
||||||
Use flash.sh to flash it via /dev/ttyUSB0

ESP8266 mDNS responder sample
|
||||||
|
|
||||||
|
This is an example of an HTTP server that is accessible
|
||||||
|
via http://esp8266.local URL thanks to mDNS responder.
|
||||||
|
|
||||||
|
Instructions:
|
||||||
|
- Update WiFi SSID and password as necessary.
|
||||||
|
- Flash the sketch to the ESP8266 board
|
||||||
|
- Install host software:
|
||||||
|
- For Linux, install Avahi (http://avahi.org/).
|
||||||
|
- For Windows, install Bonjour (http://www.apple.com/support/bonjour/).
|
||||||
|
- For Mac OSX and iOS support is built in through Bonjour already.
|
||||||
|
- Point your browser to http://esp8266.local, you should see a response.
