The data are stored in a SQLite database located at \sdcard\bt_can\btcan.db.
You can use f.e. SQLite Manager AddOn for webbrowser firefox to access these data also on your pc.
Look at menu Firefox / Web-Developer after installing to access this SQLite Manager AddOn.
The db-data are organized in four major tables:
- SECLOG is used to store data every second.
- ODOLOG is used to store data every km.
- CELL_VOLTS is used to store all cell volts values every minute.
- CELL_TEMPS is used to store all cell temp values every minute.
The app has several screens.
The screen-layout is grouped to a Panel TitleBar at the top, a Panel Overview at the left, a Panel AmpsMeter at the right and a Panel StatusBar at the bottom. The center of the screen is used for the Panel ContentView. This Panel ContentView can be switched via swipe gestures to view 1/12 different contents.
On touching the middle of Overview-Panel a screenshot is made and stored at \sdcard\bt_can\pict_.png
On touching the bottom of OverView-Panel you can define a GPS Altitude Offset, if GPS Altitude has an offset.
On double clicking the ContentView-Panel the content is maximized/restored to the screen.
Via spinner SelectPanel at the right corner of TitleBar-Panel you can jump directly to 1/12 contents.
Via spinner close to the spinner SelectPanel on all history-panels you can select various periods for viewing data, depending on availability in the db at SECLOG for time-values and ODOLOG for distance-values. Trip is a special value for history-panels. Trip uses the start timestamp from the Panel Trip Timer.
The car cames out from factory with 88 or 80 cells. You'll see all cell volts values at Panel Batt Status. The cells are organized in groups of 4 cells. Each group is equipped with 3 temperature sensors. So you'll see on panel Batt Temp 66 or 60 cell temp values.
Panel Trip History shows a bar chart where bars in holo_blue_light represent energy consumption and bars in holo_green_light represents energy regeneration.
Panel Cockpit supports most of controls - some are still missing.
Panel Maps shows the current location and show an inner green circle for half of autonomie (for bidirectional trips) and an outer green circle for autonomie (one way). You can switch between road- and satellite view. You can import POIs in gpx-format to the SQLite-db. It's also possible to reset the table POIS in SQLite-db.
Panel Maps uses Google Maps. So you need sometimes internet connection. Map data are cached locally. So if the needed data are in the local cache, you do not need internet connection.
If the android device is near the obd-ii bluetooth adapter the app connects automatically on startup. Please switch the car on first. If no connection is established, you can touch the red box in the right bottom corner to establish a connection. First of all you have to add the bluetooth-device to your android device via settings / bluetooth / pairing-devices.
