# Internet and Bluetooth Requirements

## Bluetooth is required for all mobile app activities. Internet is required for syncing and firmware updates, but is not required for other app activities.

#### Bluetooth

Bluetooth is required for all app activities for both the Proxxi Voltage App and the Hub App. Bluetooth is how your mobile device connects to the wristband.

#### Internet

An Internet connection is required to initially download both mobile apps. An internet connection is also required submit a Support ticket or to access the online knowledgebase for both apps.

For the Proxxi Voltage App, an internet connection is required for initial login and some in-app functions such as syncing data and updating firmware. Internet is not required for other in-app functions such as muting the wristband, adjusting settings, powering down the wristband, or pairing/unpairing with a wristband. 

For the Proxxi Hub App, an internet connection is required for app installation and for all in-app functions (data syncing and firmware updates).

In all circumstances, the Internet connection can be WIFI or mobile data.
