When starting the Bluetooth, note that the Bluetooth cannot be started normally, because during normal start, the bluetoothintent will be returned. enabled_action: intent. When an exception occurs during startup, no intent is returned. Android uses the callback function to solve this problem. The following is the Enable (iblustmthdevicecallback callback) process

This article is a summary of the implementation of the Bluetooth anti-loss device project, the principle of Bluetooth anti-loss device, the implementation of Bluetooth BLE interface with the Android client programming. Here is the focus on how to use the BLE interface to carry out the project, for BLE protocol, the BLE
We mentioned in the previous two articles about the Android platform Bluetooth pairing, discovery, enabling and other operations, this article began to create a socket with Bluetooth communication through the Bluetoothsocket class. Starting from Android 2.0 to support this feature,
In viewAndroidThere are few examples of Bluetooth development, and there are also few examples of Bluetooth development, so the information is not comprehensive.
Android supports Bluetooth development only from sdk 2.0, and simulators are not supported. Testing requires at least two mobile phones, which restricts the d
In the past two days, the communication between PC and Android mobile phones is limited to the level. There are two methods available: socket based on data packets and Bluetooth. Although it looks simple, it has been adjusted for more than two days. I tested the socket. The latency in the indoor WIFI environment is about 0.1 s. The latency in 3G networks is as high as 3 s, and the port seems to be disconnec

Last time, we introduced how Android uses a microphone to collect and display analog signals. This collection method is applicable to scenarios where no I/O control is required and signals are read. If the sensor itself needs to contain a control circuit (for example, the acquisition of blood oxygen signals requires infrared and infrared emissions), then the sensor it
I recently worked on a project in the lab and used Android Bluetooth development. There are many pitfalls in this project, so I still hope to write down these things and share them with you, so I don't want to go on my own.
Let's talk about the background. I am an APP that develops mobile phones and smart devices with Bluetooth (such as
I. Introduction to ANDROID low power Bluetooth (BLE) APIfrom Android 4.3 (API 18) to support the core function of Bluetooth low power, ble, ble Bluetooth protocol is the GATT protocol, BLE related classes are not many, There are several classes in the Android.bluetooth pack
When using the mobile phone, Bluetooth communication brings us a lot of convenience. So how does Bluetooth develop on Android phones? This article illustrates the knowledge of Android Bluetooth development in a practical way.

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
A collection of characteristic. For example, a service called "Heart Rate Monitor", which may contain multiple characteristics, may contain a Rate called "Heart measurement characteristic".

The following two permissions are required by ScanBle (you can choose one)
Note: Standard Bluetooth and low power consumption are required to be scanned in Android
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
