Why does the app require location information in order to find ekey bionyx devices?

The location information is needed to search for devices that use BLE wireless connections. After Android 6.0 was released in 2015, Google introduced new authorization requirements for BLE wireless connections. Android 6.0 or higher requires apps to ask for authorizations before an app can use system data and functions.
If the location services and/or the location authorizations for the ekey bionyx app are deactivated, the Android smartphone and the ekey bionyx app cannot find the hardware matching of the ekey control unit. This means that no connection can be established between the ekey bionyx app and the ekey control unit and that activation thus cannot be carried out.
