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

, 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

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

Recently in a customer to the master-slave module, based on the S130, a little farther away from the connection will appear immediately after the phenomenon of disconnection,Traced the reason, given the HCI Error code is 0x003e, for the moment do not know what the ghost, check out a post on the Internet, explained as follows:Disconnect reason 0x3e Hci_error_code_conn_failed_to_establish I use TI CC2640 master machine, mobile phone do from the mach

Accessibility-Accessibility/Accessibility Accessibility indicates the Accessibility of the webpage. W3C Web page accessibility is defined as follows: "Webpage accessibility is accessible to people with disabilities. More specifically, the availability of web pages means that people with disabilities can perceive, understand, manipulate, interact with, and contribute to webpages. Web Accessibility also benefits non-Persons with disabilities, including the elderly who are weak due to a

In the process of Bluetooth enable, multiple threads are created and the threads are bound to the queue.

To achieve the goal of separating the data from the hardware device, NetApp extends virtualization technology from the device level to the application level to enhance virtualization, while launching new versions of VFM 6.0 and snapdrive software to further the virtualization technology. NetApp founder, executive vice president and strategy director James Lau says storage virtualization is still the main a

: High reliability, security: In the case of hardware failure, data misoperation, power outages and so on, the data needs to be fully protected, can provide a complete data backup and achieve rapid recovery to ensure that the newspaper published on time. The deployment of new storage systems, so that departments distributed, independent data centralized management, to achieve data sharing, effectively reduce total cost of ownership. Excellent performance: The entire storage system should prov

files are required. For this big data file "service", wafl uses the upper-layer inode to point to the lower-layer inode. For example, when the file size is small to less than 4 kb, the file can be directly stored in inode. Save space. Thinking: in fact, Microsoft's inode only contains the address of the first data block of the file, and then the first data block contains the second data block. Therefore, inode does not need to be so large. You only need an inode of the normal size. Why does waf

To achieve the goal of separating data from hardware devices, NetApp expands virtualization technology from the device layer to the application layer to enhance virtualization functions, and also releases new versions of VFM 6.0 and SnapDrive software, let the virtualization technology go further. James Lau, Founder and Executive Vice President of NetApp, said that storage virtualization is still the main a
