Abstract: A communication device, including a wireless interface including a transceiver unit, and a controller configured to control the transceiver unit when applying a first protocol which is a Bluetooth Low Energy protocol and a second protocol which is suitable for exchanging both audio data and non-audio data. The controller is further configured to apply a first control configuration while the transceiver unit is not used for audio data reception and/or transmission of audio data via the second protocol, and to apply a second control configuration while the transceiver unit is used for audio data reception and/or transmission of audio data via the second protocol. In the second control configuration duration of BLE connection events is limited to a maximum duration shorter than the maximum duration of BLE connection events in the first control configuration.

Abstract: A method of providing hearing assistance to a at least one user wearing at least one receiver hearing assistance device from at least one audio transmission device worn by a another user, involving: automatically pairing and connecting the audio transmission device with the receiver hearing assistance device to form an ad-hoc network for exchanging network and/or control information, estimating at least one of an angular direction of the audio transmission device with regard to a viewing direction of the user of the receiver hearing assistance device and an angular direction of the receiver hearing assistance device with regard to a viewing direction of the user of the audio transmission device, admitting the audio transmission device to a wireless local acoustic area network for exchanging audio signals only if, as a predefined admission rule, the transmission device is within a field of view of one of the users.

Abstract: A communication system maintains a signal processing license within a memory of the communication system. The signal processing license allows the communication system to perform a license-enabled signal processing function on signals received from one or more devices external to the communication system while the signal processing license is maintained within the memory. As such, the communication system detects that an additional communication system is within a transfer range of the communication system, and, in response, performs a transfer operation in which the signal processing license is transferred from the communication system to the additional communication system such that the signal processing license is no longer maintained within the memory once the transfer operation is completely performed. Consequently, subsequent to the transfer operation, the additional communication system is enabled to perform the license-enabled signal processing function while the communication system is prevented from performing the license-enabled signal processing function.

Abstract: A portable communication device having a transceiver unit (30) for establishing a wireless communication link (16) using a digital modulation scheme with a packet-based frequency hopping scheme including at least one advertising channel, an antenna (32), an antenna tuning circuit (34) connected to the transceiver unit and the antenna for tuning the antenna, and a control unit (36) for controlling the antenna tuning circuit. The transceiver unit is adapted to estimate the strength of signals received in the at least one advertising channel and to supply the control unit with a signal representative of the estimated signal strength in the at least one advertising channel. The control unit is adapted to control the antenna tuning circuit such that the antenna is tuned according to the signal representative of the estimated signal strength in the at least one advertising channel.
