Abstract
A dual-signal wireless transceiver is provided, comprising: a first wireless transceiver circuit configured to transmit and receive first signals using a first protocol; a second wireless transceiver circuit configured to transmit and receive second signals using a second protocol; and a control circuit configured to generate control signals to control operation of the first and second wireless transceiver circuits, wherein the first wireless transceiver circuit is configured to disable second transmission operations by the second wireless transceiver during first transmission operations by the first wireless transceiver circuit through the use of a shutdown signal. In this method, the second protocol allows the second wireless transceiver to retransmit first signals whose transmission was disabled by the shutdown signal. Furthermore, the second protocol is a Bluetooth protocol, and the first protocol is a wireless protocol other than the Bluetooth protocol.
