Abstract
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.
