Abstract: Methods and systems for processing data are disclosed herein and may include compressing audio information on-chip within a Bluetooth® transceiver chip utilizing an audio codec implemented within the Bluetooth® transceiver chip. The audio codec may be a low complexity sub-band codec (SBC). An audio stream with the audio information may be generated outside the Bluetooth® transceiver chip. The audio stream may be generated via an audio/video distribution transport protocol (AVDTP) external to the Bluetooth® transceiver chip. A data channel may be established by the Bluetooth® transceiver chip between a Bluetooth® enabled device and a peer Bluetooth® device, for communicating the established audio stream to the Bluetooth® transceiver chip for compression. The data channel may be established utilizing a logical link control and adaptation protocol (L2CAP) and/or an advanced audio distribution profile (A2DP).

The processors and/or circuits may be operable to determine a transmitted signal power level based on the determined maximum input level. The processors and/or circuits may be operable to transmit subsequent signals via a distinct Bluetooth connection based on the determined transmitted signal power level. The data rate for signal transmission via the distinct Bluetooth connection may exceed the data rate for signal transmission via the BR connection and the data rate for signal transmission via the EDR connection.

Abstract: A method of communicating data in a Bluetooth™ low energy (BLE) module is provided. The method includes modulating an outbound communication signal into a modulated signal with a particular modulation scheme based on a modulation type, and transmitting the modulated signal to a remote device via a wireless communication connection associated with the modulation type. The method also includes receiving an inbound radio frequency (RF) signal, determining if the inbound RF signal is associated with a modulation type, and demodulating the inbound RF signal with a particular modulation scheme based on the modulation type if the inbound RF signal is determined to be associated with a modulation type. In some aspects, the inbound RF signal and outbound modulated signal have symbol rates of 2 Megasymbols per second. In some implementations, the method includes switching between a legacy BLE system and an enhanced rate BLE system.

Abstract: Methods and systems for enabling coexistence of multiple potentially interfering wireless components in a device are provided. A device may include a wireless module using a proprietary protocol and one or more modules using standardized protocols. The device further includes a coexistence arbitration module configured to arbitrate access to a shared communication medium among the wireless modules based on assertion of medium access requests by the modules and the associated priority of the asserted medium access requests. When multiple medium access requests have the same priority, precedence for access to the shared medium is determined based on additional criteria. The coexistence arbitration module may be a separate module or may be integrated into another module or distributed among the modules. The device may include a host processor for altering transmission characteristics of a module to increase the likelihood that another module can receive data within a reasonable time period.
