# Connectivity

With Glass Enterprise Edition 2 you can use wireless protocols such as Bluetooth and Wi-Fi
to stay connected. Read on to find out more about connectivity features.

## Bluetooth

Bluetooth on Glass allows you to exchange data with other Bluetooth devices such as wireless
headphones, keyboards, and barcode scanners. The
[Glass Settings](https://developers.google.com/glass-enterprise/guides/application-integration#settings) application allows you
to search for and pair with nearby devices. If you'd like to implement Bluetooth connectivity in
your applications, use Android's
[Bluetooth API](https://developer.android.com/guide/topics/connectivity/bluetooth).

> [!NOTE]
> **Note:** Before you scan for nearby devices, make sure [Location services](https://developers.google.com/glass-enterprise/guides/inputs-sensors#location-services) are turned on and necessary [permissions](https://developer.android.com/guide/topics/connectivity/bluetooth#Permissions) have been granted.

## Wi-Fi

Wi-Fi allows you to connect your device to nearby networks. The
[Glass Settings](https://developers.google.com/glass-enterprise/guides/application-integration#settings) application provides an
interface to search for and connect to nearby Wi-Fi networks. To implement Wi-Fi in your application,
use the Android [Wi-Fi API](https://developer.android.com/guide/topics/connectivity/wifi-scan).
