OpenOBD 0.3.0

Cars the automatic protocol search misses: when the car does not answer, "Try each protocol" tests all nine OBD-II protocols one by one, keeps the one that works and shows what each answered. A command that times out while the adapter is still searching no longer garbles the next one. Clearer advice for diesels built before EOBD (2004).

Installs over 0.2.0 without uninstalling.

OpenOBD 0.2.0

New: adapter check. Vehicle › Adapter › Check adapter tests which ELM327 commands your adapter really supports, version by version from v1.0 to v2.2, like the ELM327 Identifier app.

Many cheap adapters report "v1.5" or "v2.1" but implement much less. Elm Electronics never made a v1.5 at all. The check shows:

• the version the adapter actually behaves like, next to the one it reports
• which commands are missing, per version
• whether every command OpenOBD relies on works
• whether the adapter answers OK even to a made-up command, which makes its claims meaningless

The command table comes from the Version History in Elm Electronics' ELM327 data sheet. The check only sends read-only or temporary settings, nothing that writes the adapter's memory, and puts the app's settings back afterwards. Copy report gives you the result as text, handy for a GitHub issue.

If you try it, please post your result (adapter name plus the copied report) in an issue. It will show which adapters people actually have.

OpenOBD 0.1.0

First release. A small, free Android app for ELM327 Bluetooth OBD-II adapters such as the Veepeak OBDCheck BLE / BLE+. No internet permission, no account, no ads.

• Live: four gauges you choose, every sensor the car reports, CSV logging
• Codes: stored, pending and permanent codes, freeze frame, readiness monitors, guarded clear
• Vehicle: VIN, control units, calibration IDs, on-board test results (Mode 06), adapter settings
• Care: a simple service schedule; reads the odometer from the car where it reports one
• Terminal: send any AT or OBD command
• Demo: try it without an adapter

Android 6.0 or newer. Bluetooth LE needs no pairing; Classic adapters must be paired in Android first.

This is early software, so far tested on one car with a Veepeak BLE+. Reports from other cars and adapters are very welcome: please include the car, year, adapter and what Vehicle › Adapter shows.

Install: download OpenOBD-0.1.0.apk below and open it on the phone. If you installed a copy you built yourself, uninstall it first; the signing keys differ.
