Firmware Upgrade Brings New Features to Attero Tech’s unD6IO-BT Bluetooth Wallplate

July 17, 2018... The latest firmware upgrade for the Attero Tech unD6IO-BT  introduces a variety of new features that bring even more functionality to the already adaptable, commercial-ready device. Listed below are the newly available features and the applications they serve.

Bluetooth Call Bridging Mode

In addition to the standard A2DP (standard Bluetooth streaming media connection) mode that was previously supported, the unD6IO-BT now offers a “Bluetooth Call Bridging” mode for bridging cell phone audio into a Dante audio system via Bluetooth.


This feature aims to provide a straight-forward option for integrators looking to provide a seamless solution to an industry-wide issue. Even with the complex capabilities often found within enterprise networked audio conferencing AV systems built around open architecture DSPs, conversations may need to be taken offline to a cell phone call, or an executive administrator may be running late for a meeting and needs to join their call from a cell phone into the conference. With the unD6IO-BT addition of a configurable option to allow call bridging, the unD6IO-BT now offers even more flexibility in a time where Bluetooth has become a technological norm for communication and media consumption.  

Configurable Re-Connect Upgrades

One of the unique and differentiating features of the Attero Tech Bluetooth audio wall plates is the intentional limiting of Bluetooth reconnections.  This is intended to limit errant connections in public spaces where multiple users will stream audio media over Bluetooth. However, as these products have found their way into other applications such as luxury homes, multi-dwelling units (apartments/condos), private offices and operating theatres, the need for a similar user experience as found in cars and consumer Bluetooth speakers/headphones is desired where these devices reconnect to previously paired devices without user intervention.

The unD6IO-BT now offers a solution to this problem by allowing flexible pairing/connect options to the integrator tasked with tackling their clients’ Bluetooth audio connectivity needs.

Integrators now have the option to choose from three different Pairing/Connect modes for applications involving Bluetooth connectivity:

Default Mode

In the default pairing mode, a user must press the pairing button every time he or she wants to pair with the unD6IO-BT, even if they’ve paired with the device before.  This is the factory setting for the unD6IO-BT.

Reconnect Mode

In this mode, a previously paired device will be permitted to reconnect when in range of the unD6IO-BT without requiring the front panel button to be pressed.

(This mode applies to both A2DP and Bluetooth Call Bridging modes mentioned above.)

Exclusive Connect Mode

In this mode, the exclusively paired device will be permitted to reconnect when in range of the unD6IO-BT without requiring the front panel button to be pressed but is limited to a single device and is intended for restricted/personal use of the product.

AVRCP - Remote Transport Control

The unD6IO-BT has been upgraded to support Audio Video Remote Control Protocol (AVRCP) pass through for source control of a connected Bluetooth audio media device.

The unD6IO-BT can “bridge” the following transport control commands over the network so that a connected device can be operated without the user needing to be at the device.  Supported commands include Play, Pause, Stop, Next Track, Previous Track, Volume Up,Volume Down, and Mute.

Many installed AV systems in both residential and commercial markets feature control products with customizable user interfaces.  With a connected Bluetooth audio device as a source, the control system can access the device information and source content (artist / album) for display to the user.  

Application Example:

A user pairs and connects their device to the audio system through the unD6IO-BT.  They leave their device charging in the room where the device was connected and walk to another part of the venue/home but want to change songs on their device.  Instead of walking back to manually change songs on their phone. They use the AV system control panel located on the wall to select their phone as the source device and use the virtual transport controls to shuffle through songs and control the input volume level.  The panel shows the name of the connected Bluetooth device, and the currently playing song / artist / album.

unIFY Control Panel Update: Dante Domain Manager Support

The unD6IO-BT plugins for unIFY Control Panel (UCP) and Q-SYS Designer have been updated to include integrator options for real-time media transport control and monitoring of the connected device metadata (artist/album/song/device name). The device plug-in has also been updated to support DDM compatibility.
