Custom Android application development with BLE integration

The Challenge

Temperature and environmental conditions are critical when it comes to vaccine storage and transportation in the supply chain. Measuring, reviewing, and auditing temperature data during storage and transport is a full time job. The objective behind CX Gateway is to reduce the time and effort of tracking temperature for vaccines by creating a gateway that can readout many different Bluetooth Low Energy (BLE) data loggers and store this information in the cloud.

"What has impressed me the most is AndPlus' ability to understand and internalize the needs of our customers"

- Erich Roth, Director of Software Engineering, Onset

 

Product Map Sprint

During the Product Map Sprint, AndPlus worked with Onset to evaluate different methods of retrieving data from many different data loggers and sending and storing that data to the cloud. Through research and rapid prototypes, we landed on a "headless" Android solution (which could use slightly refactored code from the Onset HoboMobile Android app) that would be the basis of the Gateway software. 

The Bluetooth radio in the average smartphone wasn't built to simultaneously communicate with 50 data loggers, but the engineering team at AndPlus developed a way to make it happen. Our initial prototype achieved a 96% success rate with constant, accurate communication. With a successful proof of concept, we knew that an even more robust product was attainable to help ensure correct temperature regulation of vaccines during transport and storage.

Agile Approach

The development team at Onset already had a vision in mind. We worked closely with their engineers to create an Android application that utilized their existing technology while introducing new features. Pushing the limits of smartphone Bluetooth capabilities while maintaining near 100% reliability was a challenge we were excited to take on.

Our engineers developed within a 'Reactive Framework', which allowed them to troubleshoot and solve issues as they arose - maximizing solution reliability and effectiveness. This was important in order to create medical-grade software where reliability is essential. Now in its initial Beta release, Onset customers are providing positive feedback and we are excited to continue our co-development with this fantastic partner.

The Result
Onset and AndPlus collaborated to create an IoT solution that utilized BLE in order to continuously connect to many CX400 data loggers in succession, pull data from individual loggers, and send that data to the cloud. The CX Gateway requires little to no interaction from the end user. Individual loggers are configured in order to set the rate of which data is pulled from the CX Android mobile app (which was built with AndPlus and Onset collaboration). CX Gateway users are also able to interact with the data using Onset's HOBOware software in order to understand trends, alerts/alarms, and analytics.
The project required 50 precise readouts per hour and push updates to Onset's cloud platform, InTemp Connect. The application is used throughout the shipping process and ensures confidence that all vaccines remain at their proper temperature at all times.
 
Through our collaborative effort with Onset we accomplished just that and built compatibility for Android 4.4 and up, providing years of backwards compatibility.
