Patent ID: 10104147

Abstract:
A method for wirelessly transmitting audio signals based on the Bluetooth protocol from a Bluetooth audio source to a computer device (audio sink). An audio signal is converted in the Bluetooth audio source into an audio data packet. The audio data packets are converted into L2CAP data packets in the Bluetooth audio source based on a protocol with access to the L2CAP layer, and wirelessly transmitted. The Bluetooth audio source suppresses renewed transmission of L2CAP data packets which were erroneous or which were not received by the sink. Real-time transmission or reproduction of the audio stream or the audio signal can thus be effected. The audio stream or an audio signal on the L2CAP layer may be transmitted with a reduced repetition rate in respect of erroneous data packets. Access to RFCOMM or another data transport protocol with access to the L2CAP layer can be provided from the application layer.
