Abstract
The present invention provides a system and method for conserving power consumption of a wireless device such as a BLUETOOTH slave device. A master device polls a slave device in a polling period. The slave responds by transmitting a data packet. If there is an error in transmission of the data, the master device may transmit an ARQ (Automatic Repeat Request) to the slave device in a TIMEOUT period to indicate that the data packet was not received. The slave device may reduce power consumption or power off during that TIMEOUT and receive a retransmit ARQ in a subsequent polling period.
