EXTENDED BLUETOOTH COMMUNICATION MODES

摘要

A method and system for an improved communication mode for Bluetooth wireless devices is disclosed. Packets used in the improved communication mode are encoded using a convolutional encoder and transmitted with a particular modulation index such that the improved communication mode provides an improved link margin with respect to a communication mode specified in a Bluetooth wireless communication protocol. In this regard, the improved communication mode allows Bluetooth wireless devices to continue to communicate when a communication link between the Bluetooth wireless devices degrades, whereas otherwise the connection would be dropped. Furthermore, the Bluetooth wireless devices seamlessly switch between the improved communication mode and other Bluetooth communication modes without renegotiating the connection.

1. A method for communicating between a first wireless device and a second wireless device over a communications link, the method comprising:
by the first wireless device:
establishing a connection with the second wireless device over the communications link;communicating with the second wireless device in a first mode of communication having a first instantaneous data rate;detecting a loss of signal quality in the communications link;initiating a transition to communicate with the second wireless device in a second mode of communication having a second instantaneous data rate, wherein the transition to communicate with the second wireless device in the second mode of communication does not cause a renegotiation of the connection with the second wireless device; andcommunicating with the second wireless device in the second mode of communication.
