The first article of the new year. Recently, I am working on a small Bluetooth Lock project. There is always a problem when the mobile phone is connected to the single-chip microcomputer, and the connection to the mobile phone is also unstable. I have read many bluetooth documents, I made a summary about the Bluetooth connection.

Recently do an Android application, with Bluetooth signal control an instrument, through a Bluetooth to the serial port device, send Bluetooth signal, and then converted to serial command sent to the instrument. The Bluetooth device is as follows:How do I get this

1, Bluetooth is a short-distance, low-bandwidth point-to-point communication protocol. Bluetooth is one of the most widely used wireless communication protocols, mainly for short-distance communication, the advantage is low power consumption, transmission speed is relatively fast. But the disadvantage is also obvious, is the transmission distance is relatively short.Bluetooth is almost every mobile phone st

In recent projects, you need to implement the function of transmitting the apk via Bluetooth, which allows you to search for nearby bluetooth mobile phones and share files. From the perspective of demand, the Bluetooth transmission module provided by the android mobile phone can meet the needs, and the implementation i

This article describes the android BLE Bluetooth 4.0, that is, API level >= 18, and Bluetooth 4.0 mobile phone can be used, if the phone system version API level First send the official demo, interested in the past to see: http://developer.android.com/guide/topics/connectivity/bluetooth-le.html.

This article describes the android BLE Bluetooth 4.0, that is, API level >= 18, and Bluetooth 4.0 mobile phone can be used, if the phone system version API level first send the official demo, interested in the past to see: http://developer.android.com/guide/topics/connectivity/bluetooth-le.html.

Android ble bluetooth 4.0, which means that the API level >= 18, and Bluetooth 4.0-enabled mobile phones can be used.BLE is the core profile of Bluetooth 4.0, the main feature is fast search, fast connection, ultra-low power to maintain connectivity and transmission of data, the vulnerability is low data transmission r

Preface This chapter is about android. bluetooth. javasthclass, which is a part of Android bluetooth. It is used to describe the type, characteristics, and other information of a remote device. The getthclass () method is used to obtain the thclass object that represents the property of the remote device.

Recently on the Bluetooth operation of Android devices to do some research, the following to do some summary, version is 4.4, the list of solutions are mostly from the network, thanks to the powerful netizens:The operation of Bluetooth can be divided into regular operation, and unconventional operation. The so-called normal operation, is the interface is prompted

Generally, Android phones use the client role to actively connect to the SPP protocol device (connect to the digital sensor of the bluetooth module). The connection process is as follows: 1. Use registerReceiver to register BroadcastReceiver to obtain Bluetooth status, search for devices, and other messages;2. Use BlueAdatper for search;3. Obtain the

There are a lot of tutorials on using WiFi to connect Android devices to debug apps, but you need to use Bluetooth to communicate in your project. So it involves using Bluetooth to call ADB.1. Pairing your computer's Bluetooth with your phone (Control Panel, devices and printers, adding devices)2. Set on the phone (set

Android Bluetooth developmentrecently do Bluetooth car, need the Android side to control the movement of the car, this article records the development process. Use HC-06 wireless Bluetooth serial pass module. This is also true for other
