Here is the progress so far
In this post, I present the final wearable and submission. It is important to package the contents into an ergonomic wearable and make it serviceable. The final challenge is to create something presentable and usable.
The Complete Design Review
The four modules were segregated for design reuse and I designed and printed all enclosure using Fusion 360 and a Cel Robox. The idea is to create a wearable meant for safety and one that uses all Texas Instruments parts. The MSP432 is the hero of our design and runs TI-RTOS and a number of tasks for all the functions. BLE communication is handled by the TI CC2650 which reduces the BOM and power consumption. The BQ25570EVM is used in conjunction with a solar panel and a SuperCap to power an MSP430 and Sharp96 Booster Pack from TI. Information is relayed via serial communications to provide a visual indication of status and data display. The Qi Charging Power Pack is designed around the E14 and TI Fuel Tank Booster Pack and WE and TI Wireless Charging Kit to provide power to the main components.
All the above components are mounted in a jacket as explained in the proceeding sections.
One More TI Part
Since we are using BLE and it's a wearable, I decided to put in one more part. I had a CC2640 LED module from a previous challenge and design an enclosure around it. It is powered from another Fuel Tank adhering to my policy of using all TI parts.
This module adds another layer of visual indications that can work directly with the BLE app.
The Wearable Electronics
Creating an ergonomic wearable was a challenge that was taken up by my better half. Using ribbons, thread, and other accessories, she assembled all the parts into the final wearable.
The Final Product
My better half has done an excellent job in creating the final product.
The solar panel sits comfortably at the back exposed to light sources and the Sensors Booster Badge is mounted on the front along with the LCD. The LED light is converted into the badge with it's power source in the adjacent pocket. All the wiring is hidden inside going towards the Core module which is in the left pocket. The exposed headers under the jacket allow for mouting of the power pack with ease.
The Video Demonstration
A picture is worth a thousand words and in this case, I needed lots to explain the functioning.

I promised a code upload and to download the code please visit https://github.com/inderpreet/Project-SafetyJacket
The 3D models can be downloaded from https://pinshape.com/users/29645-inderpreet-singh-ip
I managed to stick to my original plan and created a working Wearable with all TI parts. I am happy with the result and though I am not an Android Programmer, I have started the process of working with Java. The project works and can be expanded depending upon requirement. The intent was to be able to have two way communication and the proof of concept is presented thought the software part is still a bit rough. Hopefully this is an incentive for me to work on other skills.
