Development

===========

Preparation

-----------

Install the USB driver for your ESP8266 and find out on which

port your device is avaible. For convinience you can save that

information in your `~/.bashrc` or `~/.bash_profile` file.

.. code: bash

    export MOS_PORT=/dev/cu.SLAB_USBtoUART

If you don't wanna do that, you have to add the port to each 

command.

.. code:: bash

    mos --port /dev/cu.SLAB_USBtoUART COMMAND

Build

-----

You need to install Docker to build it locally.

.. code:: bash

    git clone https://github.com/vergissberlin/coffee-bin-mqtt

    cd coffee-bin-mqtt

    mos build --platform ESP8266 --local --verbose

    mos flash --esp-erase-chip --esp-baud-rate 115200 --esp-flash-params "dio,4m,40m"

Debugging and configuration

---------------------------

.. code:: bash

    mos wifi --port /dev/cu.SLAB_USBtoUART WIFI-SSID WIFI-PASSWORD

    mos console --port /dev/cu.SLAB_USBtoUART

Upload files

------------

.. code:: bash

    mos put --port /dev/cu.SLAB_USBtoUART fs/init.js
