Abstract: A Bluetooth internet protocol packet transmitting device and method are provided. The device includes a Bluetooth protocol stack, a Bluetooth controller and a host control interface. The Bluetooth protocol stack is configured to store an internet protocol stack and a host control interface driver. The Bluetooth controller generates at least one data packet based on an internet protocol packet, wherein the at least one data packet corresponds to an asynchronous connection data format. The Bluetooth controller transmits the at least one data packet to the host control interface driver. The host control interface driver determines whether the at least one data packet is an asynchronous connection data packet. When the host control interface driver determines that the at least one data packet is the asynchronous connection data packet, the at least one data packet is transmitted to the internet protocol stack.

Abstract: A Bluetooth network establishing system and method are provided. The system includes a plurality of node devices and a gateway device. The gateway device is used to connect a Bluetooth network to an external network and broadcast a first connectable undirected advertising packet.

Abstract: A Bluetooth network establishing system and method are provided. The system includes a plurality of node devices and a gateway device. The gateway device is used to connect a Bluetooth network to an external network. A first node device of the node devices broadcasts a first inquiry operation. In response to the first inquiry operation, the gateway device in a first inquiry scan state sends a first extended inquiry response and executes a first page scan state. The first node device executes a first page operation, wherein the first page operation determines whether to establish a first communication connection with the gateway device to join the Bluetooth network according to the first extended inquiry response. After the first node device joins the Bluetooth network, the first node device executes a second inquiry scan state.
