The app asks for permission to enable Bluetooth as well as location and mobile data services. Are they necessary to connect with the locker?

Yes, because the mobile app connects with the locker via Bluetooth as a communication method. Therefore, the user must allow connection via Bluetooth and enable location, as well as make sure that mobile data (internet) is turned on. Bluetooth connectivity requires the user to be close to the locker. At the same time, only one person can use the DPD Pickup Station locker.
