Connect to Bluetooth and USB-C devices

Pair Bluetooth devices

HoloLens 2 supports the following classes of Bluetooth devices:

  • Mouse
  • Keyboard
  • Bluetooth audio output (A2DP) devices

Note

External microphones cannot be used. HoloLens 2 uses its built-in microphone array.

HoloLens (1st gen) supports the following classes of Bluetooth devices:

  • Mouse
  • Keyboard
  • HoloLens (1st gen) clicker

Note

Other types of Bluetooth devices, such as speakers, headsets, smartphones, and game pads, may be listed as available in HoloLens settings. However, these devices aren't supported on HoloLens (1st gen). For more information, see HoloLens Settings lists devices as available, but the devices don't work.

Pair a Bluetooth keyboard or mouse

  1. Turn on your keyboard or mouse, and make it discoverable. To learn how to make the device discoverable, look for information on the device (or its documentation) or visit the manufacturer's website.

  2. Use the bloom gesture (HoloLens (1st gen)) or the start gesture (HoloLens 2) to go to Start, and then select Settings.

  3. Select Devices, and make sure that Bluetooth is on.

  4. When you see the device name, select Pair, and then follow the instructions.

HoloLens (1st gen): Pair the clicker

  1. Use the bloom gesture to go to Start, and then select Settings.

  2. Select Devices, and make sure that Bluetooth is on.

  3. Use the tip of a pen to press and hold the clicker pairing button until the clicker status light blinks white. Make sure to hold down the button until the light starts blinking.

    The pairing button is on the underside of the clicker, next to the finger loop.

    The pairing button is beside the finger loop

  4. On the pairing screen, select Clicker > Pair.

HoloLens 2: Connect USB-C devices

HoloLens 2 supports the following classes of USB-C devices:

  • Mass storage devices (such as thumb drives)
  • Ethernet adapters (including ethernet plus charging)
  • USB-C-to-3.5mm digital audio adapters
  • USB-C digital audio headsets (including headset adapters plus charging)
  • Wired mouse
  • Wired keyboard
  • Combination PD hubs (USB A plus PD charging)

Note

Some mobile devices with USB-C connections present themselves to the HoloLens as ethernet adaptors, and therefore could be used in a tethering configuration, starting with Windows Holographic, version 2004. USB LTE modems that require a separate driver, and/or application installed for configuration are not supported.

In response to customer feedback, we have enabled limited support for cellular connectivity tethered directly to the HoloLens via USB-C. Tethered connectivity only works for devices that support the generic Microsoft RNDIS driver implementation and that don’t require any additional drivers or application installs. Such device, when connected, will automatically appear as a new Ethernet connection in the HoloLens 2 Network Settings UI. Please consult your device’s manufacturer for further details on whether it supports the generic Microsoft RNDIS driver.

  2. On the list of devices that appears, select an available device.

  3. Complete the pairing to begin projecting.

Disable Bluetooth

This procedure turns off the RF components of the Bluetooth radio and disables all Bluetooth functionality on Microsoft HoloLens.

  1. Use the bloom gesture (HoloLens (1st gen)) or the start gesture (HoloLens 2) to go to Start, and then select Settings > Devices.

  2. Move the slider switch for Bluetooth to the Off position.
