OVERVIEW:

The project aims at improving efficiency of an infrastructure by monitoring and improving 3 major factors:

• Human Comfort (Implemented on low power node 1) : Achieved by monitoring humidity and air quality Index values.
• Effective Space Utilization (Implemented on friend node) : Achieved by monitoring the noise level and the number of people in an area.
• Energy efficiency ( Implemented on low power node 2): Achieved by using artificial lights based on the amount of luminous intensity.

This repository contains code for Low Power Node 1 described above , implemented by Puneet Bansal

FEATURES:

Features:

• Configuration of the nodes as LPN and successful friendship establishment
• Integration of CCS811 gas sensor and on board Si7021 humidity sensor.
• Ability to send valid sensor data using level model to the friend node.
• Ability to send type of sensor data using on_off model to the friend node.
• Use of persistent data.
• Use of state machines for the sensor interfacing.

ECEN 5823 Bluetooth Mesh Skeleton Project

This project contains skeleton code used for coursework in University of Colorado ECEN 5823 IoT Embedded Firmware.

Below is an overview of the sequence used to generate this repository:

• The project was generated starting with the new project Wizard built into Simplicity Studio 4.
• The AppBuilder project was used with application type "Bluetooth Mesh SDK" with version 2.11.2.0 and Bluetooth SDK 2.9.3.0, application stack "Bluetooth Mesh SDK 1.4.1.0"
• The SOC- BT Mesh Empty project application was used.
• Board and part were configured for BRD4104A Rev 00 and EFR32BG13P632F512GM48 respectively
• Configurations were setup to target GNU ARM 7.2.1.
• Simplicity project Workspace paths were setup to pull in emlib functions needed for display support, including middleware/glib directory and glib/glib glib/dmd directories
• Relevant emlib project files were copied from SiliconLabs\SimplicityStudio\v4\developer\sdks\gecko_sdk_suite\v2.5\platform as needed and added into the respective directories at the root.
• The main.c file in the root folder was renamed gecko_main.c. Contents of the main while loop were moved into functions and the main() function was #ifdef'd out.
• The src subfolder was added to contain code specific to the ECEN 5823 course and source files were added to support ECEN 5823 and the simplicity studio exercise assignment.
