dynOBD is an android application that keeps track of statistics about any given car trip. It uses bluetooth to connect to an OBDII dongle that is connected seperately to the car's DLC. Instructions on connecting the dongle to the car can be found here. Alternatively if there is no access to an OBDII dongle then the user can generate simulated data which is explained in further detail down below.
- Ensure that the switch at the bottom of the app.
is ON as shown. - Only the datastream is simulated, so you still need to connect to any bluetooth device before proceeding
- Turn on the Bluetooth to your computer <img src="img/bluetooth_on.png"" width="50"/>
- Pair your phone with you computer
- Launch dynOBD
- Click the
Button - Select your computer from the list of paired devices
- Click the
Button - The data will simulate acceleration to about ~100 km/h and ~2200 RPM and begin to fluctuate around those ranges.
- You can proceed to use the app as normal from this point on
- Connect the Dongle to the Car DLC, for more detailed instructions visit this page
- Ensure that the bluetooth is on, there should be a power button and lights indicating that the device is on
- Start your car
- Before launching the app, pair your phone with the OBDII dongle
- Launch dynOBD
- Click the Button
- Select the device from the list of paired devices
- Click the Button
- Can proceed using the app as normal from this point on
