I need an Android application that pairs with an ELM327 Bluetooth OBD-II adapter and performs a very limited set of diagnostic tasks. The goal is to give me a clean, lightweight tool rather than a full-blown scanner.
Core behaviour • When the user taps “Connect”, the app must discover and bond with a standard ELM327 device and keep the link alive. • Once connected, it should read live PIDs for engine RPM and battery voltage/status and refresh them smoothly on screen. • A single button should read any stored trouble codes and, when pressed again, clear them. No additional graphs, logging or fuel-consumption features are required.
Tech notes I am comfortable with you writing the project in either Kotlin or Java inside Android Studio; please use the standard Bluetooth APIs (or a lightweight library if it speeds development). PID queries can be hard-coded—no dynamic command builder is necessary. The interface can be minimal: two large numeric fields for RPM and battery, plus the read/clear button.
Deliverables Full Android Studio project with well-commented source. One signed release APK I can load directly onto my phone. A short README explaining how to pair the adapter and which PIDs you used.
Acceptance I will test by pairing the app with my own ELM327 dongle; connection must succeed within 10 seconds, RPM values should update at least twice per second, and clearing codes must return the standard success response.
If this sounds straightforward to you, let me know your timeline and any questions you have.
