This is a common choice for applications.· Service Discovery Protocol the Service Discovery Protocol (SDP) is used to locate and describe the services provided or available by bluetooth devices. The application is mainly used when it is set to communicate with another bluetooth device.· The Host Control Interface the Host Controller Interface (HCI) driver encapsulates high-level modules for commun

Thus, Microsoft has provided a voice gateway service to support Bluetooth headsets, so what we want to do is to enable the Voice Gateway Service (AG).3How does the Bluetooth headset work? Here's how the Bluetooth

I recently focused on Bluetooth headsets and made a simple process analysis.After decoding, the audio data is written to the device in AudioFlinger. Here we mainly look at the android_audio_h1_c and liba2dp. c In AudioFlinger, AudioPolicyManager, external/bluetooth/bluez/audio.

Time to learn the next JavaScript and jquery event design, the harvest is quite large, summed up this paste, and you share. (i) Several ways of event binding There are 2 ways in which JavaScript binds event handlers to the DOM: Binding in HTML documents and binding in JS code.

First of all, figure out what is the event in JS, and how the event model is designed in JS. What is event bubbling?What is "event bubbling"? Suppose there is a glass of water, and the water is divided into layers of different colors in some magical way. At this point, a bubble emerges from the bottom, and the bubbles

Early events, as a means of sharing server computing load, are specific interactions that occur in real documents or browser windows, such as click Buttons, drag and drop files, and so on. We can use listeners to schedule events and respond when an event is released, a pattern called the Observer model. Event FlowThe event flow is the order in which events are re
