Abstract
A wireless handset or wireless headset includes a Bluetooth transceiver that is coupleable to an external Bluetooth compatible device, that sends the first audio data to the external Bluetooth compatible device and that receives the second audio data from the external Bluetooth compatible device. The Bluetooth transceiver includes a first integrated circuit that includes a memory module that stores a plurality of operational instructions for implementing a plurality of protocol layers of a Bluetooth protocol, a processing module that executes the plurality of operational instructions, and a first interface module. A second integrated circuit includes a second interface module that couples data to and from the first interface module, an RF transceiver that modulates a first baseband signal to produce a transmitted RF signal, and that demodulates a received RF signal to produce a second baseband signal, and a baseband module that generates the first baseband signal based on data received from the first interface module via the second interface module, and that generates data based on the second baseband signal to send to the first interface module via the second interface module.
