====== Project OrBit ======

This project's aim to develop an automation network to [[monitor/control]] a variety of device in home or office environment.
The network is structured as a decentralized [[stack|mesh network]], using wired and wireless links.
Multiple level of interface are accessible to use and administer the network.

This is a rather large project, the main goal is to provide a standardized interface for communication and data gathering. 
----
===== Presentation =====
[[Boards:]] will consist of a [[nodes:core]] and [[boards:|module(s)]].

All [[nodes:core]] will be the same to facilitate developpment, but [[boards:|module]] will change depending of the usage. 

A smart implementation of [[https://en.wikipedia.org/wiki/Mesh_networking|mesh]] inspired network will allow device to interract with each others, wheter it be [[https://en.wikipedia.org/wiki/RS-485|wired]] or [[http://www.silabs.com/Support%20Documents/TechnicalDocs/EZR32WG330_DataSheet.pdf|wirelessly]] 

----

===== Synthesis of objectives ===== 
  - [[boards:|Module]] should be able to upgrade their firmware using existing network capability
  - Automated task should be customizable via an interface
  - Network communication must be transparent to user application

----

===== Goal and expected results ===== 
  - Automate task based on environmental or time-based trigger
  - Create task with a dedicated user interface
  - Firmware upgrade propagation through the network
  - Node interconnection available even without direct access (mesh)

----

===== Planning ===== 
  - Project requirement and goal
      - Basic Wiki for documentation
      - Happy gecko test for user introduction 
  - [[boards:mantle|Mantle]] version 1.0
      - Firmware upgrade from auxiliary memory
      - Basic wireless communication
      - Basic RS-485 communication
  - More later
