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 present application provides a method for processing broadcast packets by a Bluetooth controller, a Bluetooth controller and a Bluetooth device. The method for processing a broadcast packet by a Bluetooth controller provided by the present application, the Bluetooth controller includes a link layer and an HCI layer, and the method includes: when the link layer receives a broadcast packet, adding one to the number of broadcast packets ; If the number of broadcast packets exceeds the preset threshold, the link layer discards the latest received broadcast packets, and reduces the number of broadcast packets by one; otherwise, the link layer pushes the received broadcast packets to the HCI layer; The HCI layer organizes a preset number of broadcast packets into event packets, and subtracts the preset number from the number of broadcast packets, wherein the preset number is less than or equal to the preset threshold. The method for processing broadcast packets by the Bluetooth controller, the Bluetooth controller and the Bluetooth device provided in the present application can control the number of broadcast packets in the Bluetooth controller, and further control the number of event packets, so as to reduce the possibility of Bluetooth host blocking.
Description
technical field [0001] The present application relates to the technical field of bluetooth, in particular to a method for processing broadcast packets by a bluetooth controller, a bluetooth controller and a bluetooth device. Background technique [0002] Distinguished by the initiative to create a connection, Bluetooth devices include Bluetooth masters and Bluetooth slaves. 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. Wherein, 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 decides whether to establish a connection with the Bluetooth slave device after discovering the Bluetooth slave device. [0003] In t...
