Both Bluetooth and Wifi allow to connect coffee machine and mobile phone, so you can control it remotely.
The difference is that:
- Bluetooth relies on the Bluetooth technology to connect and communicate with the coffee machine locally without the aid of the Cloud (hence you don't need to create a user DeLonghi account in order to use it). Bluetooth technology has a small range, for this reason you must stay close to the coffee machine to control it remotely
- WiFi instead relies on the internet connection and to your Home Wi-Fi network to communicate with the cloud and the coffee machine, so you need to create a user DeLonghi account in order to login into the app and then control your WiFi machine. Moreover you can control Coffee Machine from a wider distance.
