I’ve also experience something similar with my capstone project. We had multiple components or call them sensors, in order to finish our final project. Our project’s goal was to measure three different biometrics data (blood glucose, blood oxygen, and activity). The biometric data will then be transmitted to a UI. We distributed the task evenly at first, coding, design and software. Once we got each individual component working, our next task was to make them communicate with each other and send the data to the web. Later we realized that the UI and our sensors were not compatible and it was not possible to write to the UI. We had to go back and research a new way to transmit data using a different code language in order to transfer data.
