There are multiple threads in the Bluetooth process, where the HCI thread is responsible for processing and sending and receiving the Bluetooth host side and controller.This article analyzes the process of data processing for this thread.1. HCI-related interfacesFirst look at the related interfaces of HCI: in HCI_LAYER.C: const hci_t *hci_layer_get_interface ()

Dsads1. OverviewHCI supports four types of grouping: Command group commands Packet Asynchronous data grouping asynchronous Packet Synchronous Data Packet Events Group Event Packe The grouping type is a byte value before the HCI group. The packet type has the following values: Packet Packet Type command 1 asynchronous

Data Structure 1, hci_event Indicates the hardware status of the Bluetooth controller. Enum hci_event { Device_up, device Enabled Device_down: Disable the device. The device_error device has an error. }; Header file: bt_hcip.h2. hci_type Indicates the data packet type. enum HCI_TYPE { Command_packet = 1, command package Data_packet_acl = 2, access control list data Data_packet_sco = 3, connection-oriented data synchronization Event_packet = 4, event Etype_finish = End mark of 5 packets }; Header

, and traverse tasklet_actionThe tasklet_vec linked list calls each tasklet function to complete the Soft Interrupt operation.That is, call hci_rx_task () That is, when urb exists, hci_rx_task () is finally called () When the package type is HCI event, call hci_event_packet ()In hci_event_packet (), the system determines the event and processes it. The following uses hci_ev_disconn_complete as an example to see how the event is processed. This event i
