The Challenge

This project went through two stages of evolution: the first stage included a technology that the client developed inhouse using Bluetooth LE and a Raspberry Pi, which required the project to integrate this technology and custom design within the android app development and ios app development cycles. The second stage, it’s current form, came from the limitations of said technologies, evolving into an Envoy Station with microcontrollers.

All throughout the two stages of the project, managing real time data is a crucial part of the development cycle. This was also the company’s first time using Bluetooth LE technology, adding a learning curve to the project.

The Solution


The project requires a mix of fast and efficient communication, both external and internal, as well as our inherent adaptability to new technologies. This approach, as well as using alternative technologies to speed up the software development process, pushes the project forward and allows for the team to understand what are the best solutions for the job.

This is how we came to use microcontrollers over a Raspberry Pi, and integrating AWS Lambda for capturing real time data.
