Overview
Drive lah runs a car-sharing service in Singapore. We built the React Native application that connects a renter's phone to the car's device over Bluetooth Low Energy: sending commands, managing the connection, authenticating, and encrypting the traffic with AES-CBC with CRC checks, together with the back-end API that supports it.
What we built
- React Native app for iOS and Android
- Bluetooth Low Energy connection to the in-car device: commands and connection management
