Colorado: 802.11.4 concentrator on Raspberri PI

STEAM Colorado project logo
Colorado (river) project is addressed to develop a concentrator software stack coded in Java running on Raspberry PI hardware (Raspbian OS) using 802.15.4 communication for accessing to its litems by integrating a Digi XBee 802.15.4 module.

The objectives of the project are, in order:
  1. Supporting the role of a 802.15.4 PAN coordinator, ie, creating a 802.15.4 star network and granting access to 802.15.4 end nodes (litems).  
  2. Developing the STEAM litem protocol (from the concentrator side) to allow the concentrator-litems integration
  3. Developing the STEAM concentrator protocol (from the concentrator side) to allow the concentrator-manager integration.
The code is located in the subdirectory SteamProject/software/concentrators/802.15.4/raspbian/colorado/ of the GitHub repository.

Colorado river is closely bound to the state of Colorado. For that reason, the above icon has been selected to represent graphically this project. This icon is shared with the "Elbert" 802.15.4 litems project.

Current status

The project has completed Task 00 (Provide project infrastructure) and therefore the milestone M00 (Project infrastructure available) has been reached.
