As we wanted to focus on the integration, we confirmed that the simulated mobile application that I implemented can be installed on Max’s Android phone. Because a Bluetooth library can’t be used in the Expo environment, we decided to eject Expo (deployment platform). We found that there are two available Bluetooth libraries and determine which one is better to use for our application. The integration task will be continued, and once we have a stable application environment, the front-end UI will be completed.
