In this way, if the Bluetooth controller receives too many broadcast packets in a short period of time, it is easy to concentrate on sending too many event packets to the Bluetooth host in a short period of time, resulting in the Bluetooth host not processing data in time, and even Blocking, which in turn affects the stability of the system

The invention provides a method of a Bluetooth controller for processing broadcast packets, the Bluetooth controller and a Bluetooth device. The Bluetooth controller comprises a link layer and an HCIlayer. The method of the Bluetooth controller for processing the broadcast packets comprises the steps of adding one to the number of the broadcast packets when the link layer receives a broadcast packet; if the number of the broadcast packets is beyond a preset threshold value, discarding the newly received broadcast packet and subtracting one from the number of the broadcast packet by the link layer; otherwise, pushing the received broadcast packet to the HCI layer by the link layer; organizing the broadcast packets in a preset number into an event packet and subtracting the preset number from the number of the broadcast packets by the HCI layer, wherein the preset number is smaller than or equal to the preset threshold value. According to the method of the Bluetooth controller for processing the broadcast packet, the Bluetooth controller and the Bluetooth device, provided by the invention, as the number of the broadcast packets in the Bluetooth controller can be controlled, the number of the event packets can be controlled, and the blockage possibility of a Bluetooth host can be reduced.
Description
technical field [0001] The present application relates to the field of Bluetooth technology, and in particular, to a method for a Bluetooth controller to process broadcast packets, a Bluetooth controller and a Bluetooth device. Background technique [0002] Distinguished by the initiative to create a connection, Bluetooth devices include Bluetooth master devices and Bluetooth slave devices. The Bluetooth master device can actively connect to the Bluetooth slave device, and the Bluetooth slave device sends a broadcast to be connected by the Bluetooth master device. In the Bluetooth specification, a Bluetooth master device can connect with multiple Bluetooth slave devices. Among them, the Bluetooth slave device is discovered by the Bluetooth master device by sending a broadcast (the broadcast contains its own relevant information), and the Bluetooth master device determines whether to establish a connection with the Bluetooth slave device after discovering the Bluetooth slave...
