Abstract
A system and method for minimizing Bluetooth packet retransmission is disclosed. The Bluetooth device creates a channel map as is currently done. However, the Bluetooth device also establishes a 'clean channel' threshold. In relatively low noise environments, all of the channels in the channel map may also be considered clean channels, such that all of the channels in the channel map are used for Bluetooth packet transmissions. However, in noisy environments, some of the channels in the channel map may not be denoted as “clean channels”. In this situation, the Bluetooth device may transmit NULL or POLL packets when these channels are scheduled to be used and transmit the actual data packet in the next scheduled slot on a clearer channel.
