OBD2 ELM327 Dashboard

This application will request data from an OBDII Bluetooth adapter connected to a vehicle using basic parameter IDs (PID). Once you've found and connected your OBDII device to the app, the app will start collecting data from the vehicle in real-time by sending PID codes.

An OBDII-connected device provides the value by identifying the PID as one for which it is responsible. The responses for each PID are then converted into useful information and shown in the app.

Why does the app need access to the phone's storage?

The storage permission is an optional permission you only need to enable when exporting the sensor data to a CSV file.
