3.2 Functional requirements for the Receivers
3.2.1 Bluetooth Profiles Used and Required
The receiver functionality developed is using the Bluetooth Headset Profile, Headset Role and the
Hands-free Profile, Hands-free role, as described in reference [3] and reference [4]. It also support
the Advanced Audio Distribution Profile acting as an Audio Sink, see reference [2].

The unit may be interfaced over Bluetooth to external devices (e.g. phones) supporting the Bluetooth
Headset Profile, Audio Gateway Role or the Bluetooth Hands-free Profile, Audio Gateway Role.

3.2.2 General Module Interface
On the receiver there are 3 input pins, volume+ (VOL-UP), volume- (VOL-DOWN) and a multi-
function input (MULTI-FUNCTION) used as the main user inputs (later called VOL+, VOL- and MF
inputs). These may be used in different combinations to initiate different actions. Some actions may
be initiated by keeping an input activated for a certain amount of time.

There is Talk Indicator input pin (TALK-IND, later called TI), which must be generated by the host
electronic on the receiver. The TI shall move from inactive to active when the receiver user starts to
talk. The TI shall move back from active to inactive when the when the user stops to talk AND when
no sound is heard in NF Out left and NF out right.
electronic on the receiver. The TI shall move from inactive to active when the receiver user starts to

no sound is heard in NF Out left and NF out right.
A Mute output pin (NF-MUTE) is used to mute the sound when required. When active the sound
shall be muted by the host electronics.
shall be muted by the host electronics.
Two LED output pins (red and green) and the ability to generate sound on the sound output are used
as indicators. It uses both LED combinations and blinks respective the sound to indicate multiple
modes and other indications.
