BLUETOOTH DEVICE, PROJECTION DEVICE AND DATA TRANSMISSION METHOD

摘要

A Bluetooth device used for data transmission between first and second peripheral devices is provided. The Bluetooth device includes a processing circuit and a Bluetooth chip configured to be capable of being operated in a transmitting mode and a receiving mode for data transmitting and data receiving, respectively. In the transmitting mode, a first communication link is established between the Bluetooth chip and the first peripheral device through a first communication protocol. The processing circuit establishes a second communication protocol. In the receiving mode, a second communication link is established between the Bluetooth chip and the second peripheral device through a third communication protocol. The second peripheral device transmits a data to the Bluetooth chip through the second communication link and the Bluetooth chip transmits, based on the second communication protocol, the received data to the first peripheral device through the first communication link simultaneously.

主权项

1. A Bluetooth device used for data transmission between a plurality of peripheral devices including a first peripheral device and a second peripheral device, the Bluetooth device comprising:
a processing circuit; and a Bluetooth chip, electrically connected to the processing circuit and configured to be capable of being operated in a transmitting mode and a receiving mode for data transmitting and data receiving, respectively, wherein when the Bluetooth chip is operated in the transmitting mode through a control of the processing circuit, a first communication link is established between the Bluetooth chip and the first peripheral device through a first communication protocol, wherein the processing circuit is configured to establish a second communication protocol and the second communication protocol allows the Bluetooth chip operated in the receiving mode to perform a data synchronous transmission, wherein when the Bluetooth chip is operated in the receiving mode through a control of the processing circuit, a second communication link is established between the Bluetooth chip and the second peripheral device through a third communication protocol, wherein the second peripheral device transmits a data to the Bluetooth chip through the second communication link and the Bluetooth chip transmits, based on the second communication protocol, the received data to the first peripheral device through the first communication link simultaneously.
