1. A method of communicating between a central device and a peripheral device in a Bluetooth network during a sniff interval, wherein a plurality of packets are transmitted by the central device to the peripheral device during the sniff interval, the method comprising:
transmitting a first packet from the central device to the peripheral device using a previously negotiated transmit power; and
transmitting, from the central device to the peripheral device, at least one of the plurality of packets remaining to be transmitted using a transmit power lower than the previously negotiated transmit power, after a response to any of the plurality of packets has been received from the peripheral device.
