Enter app settings through the three dot menu top right.

Select the paired eChook bluetooth device from the bluetooth devices menu

Select which (if any) data upload service to use from the Data Upload menu (you may need to dismiss the "waiting for throttle" notification to see the 'Upload To' option) Note that the Omni app continues running when exited. To exit the app, select 'Close' from the three dot menu. When running in the background a notification is displayed to inform you.

The app needs a little configuring before it is ready to log data. Open the app and go into the Settings menu.

First select which bluetooth device to log data from. Tap ‘Select Bluetooth Device’ and select the eChook you just paired from the list:

Now enter the car name. This will be added to the log files.

If the car is running gears, enter the number of teeth on the motor sprocket and the number of teeth on each gear on the wheel side. The app will calculate the possible gear ratios and try to identify and log which the car is running on. If the RPM and speed data is too noisy or too low resolution, this feature may not work very well.

While you are here you can enable Location tracking, which will enable logging of GPS speed, location and altitude and is needed in order for the app to detect laps.
