Abstract
Described are techniques for modifying the data rate used to transmit audio data from a master device to slave devices. After receiving a signal, each slave device requests transmission of one or more packets and reports an individual error rate. A cumulative error rate may also be determined based on the individual error rates and the retransmission requests. If any individual error rate or the cumulative error rate exceeds a maximum threshold, the data rate used to transmit the audio data is decreased. If an individual error rate is less than a minimum threshold, the data rate may be increased. If an error rate exceeds a critical threshold, the data rate may be reduced to a minimum value supported by the devices.
