Abstract

An integrated cordless telephone system and Bluetooth compliant dongle are taught. The cordless telephone operates in accordance with the Bluetooth specification in both of a voice communications and data communications mode of operation. In the data communications mode, a cordless handset portion of the cordless telephone is interconnected to a computing device and performs the function of a Bluetooth compliant dongle. Multiple cordless handset are supported within a single Bluetooth piconet, and thus the cordless telephone piconet can provide Bluetooth compliant wireless interconnectivity among a plurality of computing devices. In addition, telephony based features are implemented within certain computing devices by application of the present invention.

Claims

1. An apparatus, comprising:

a cordless telephone transceiver;

a Bluetooth circuit coupled to said cordless telephone transceiver;

a serial port coupled to said Bluetooth circuit, and

wherein said Bluetooth circuit is operable to couple serial data between said serial port and said cordless telephone transceiver, thereby communicating said serial data according to the Bluetooth radio communications protocol.

2. The apparatus in claim 1, and wherein said serial communications port is a Universal Serial Bus compliant serial port.

3. The apparatus of claim 1, further comprising a software means executable on a separate computing device enabling the coupling of data signals between said separate computing device and said Bluetooth circuit, though said serial port, for coupling said data signals via the Bluetooth radio communications protocol by said cordless telephone transceiver.

4. The apparatus of claim 1, further comprising:

a memory for storing user data coupled to said Bluetooth circuit, said Bluetooth circuit operable to couple data signals with said memory, and

a software means executable on a separate computing device for synchronizing data stored in said separate computing device with user data stored in said memory via said serial port while said separate computing device is coupled to said serial port.

5. An integrated Bluetooth dongle and cordless telephone, comprising:

an audio circuit, having an audio signal interface coupled to a microphone and an earphone;
