Android 8.0 has introduced a new function which is causing issues when the Tahuna app is in the background. This may lead to the app closing and your E-Bike/sensor connection being dropped (Bluetooth turned off) or the loss of data, eg. an ongoing recording or navigation.

To prevent this from happening, you can enter the settings menu of your phone, find the battery management section and turn off battery optimization for the Tahuna app.

If you are having trouble with the GPS signal, it might be worth trying to explore the solutions below:

– Google’s Play Services app permissions

This app should have permission to use Location services. To enable this, enter ‘Settings’ within the operating system, select ‘Location’ and add the Play Services app to the list.

– Location accuracy (Android 6.0 and higher)

You can set the Location accuracy of applications within the app’s settings (OS settings/Applications/TAHUNA). For optimum performance, TAHUNA’s location accuracy should be set to ‘High’.

TAHUNA needs permissions in order to perform certain tasks. These include the location (to locate you on the map), Bluetooth (in order to connect to sensors), the camera/gallery (to attach pictures to your tours) and storage (to look up/manage GPX and TGPZ files).

If you have a Teasi Core, you will notice that it asks for permissions upon pairing. These are access permissions to your contacts and messages and they are only needed so we can display notifications about incoming calls/messages on the Teasi Core’s screen.

If you have a Teasi Core bicycle computer, you can pair it with your smartphone and activate the Navigation, Fitness and Gadget packages for free.

To do so, please click this link and follow the instructions of the step-by-step guide.

If you have a Fischer E-Bike, you can pair it with your smartphone and activate the E-Bike package for free.

To do so, please click this link and follow the instructions of the step-by-step guide.

If you have a StatCap sensor, you can pair it with your smartphone and activate the Navigation, Fitness and Gadget packages for free.
