Class wraps all the Android bluetooth internals needed to establish and maintain a serial communication with bluetooth. So I figured Id compile a set of the major points you need to know to get the Bluetooth Serial Port Protocol SPP working on an Android app.

Please note that the Bluetooth module used in this tutorial is not compatible with iOS devices - instead you will need a Bluetooth LE Low Energy module or an Arduino-compatible with onboard BLE. The RFCOMM Radio Frequency Communication bluetooth protocol is made on top of the L2CAP Logical link control and adaption protocol protocol Provides emulated RS-232 serial ports and is also known as the serial port emulation. The Serial library requires Android OS 20 or above API level 5 or above.

Pin number 2 and pin number 3 will be used as the Serial Port which will be defined in the programming. Choose the HC-05 device under Device that will use the COM Port drop down and then click OK. Find the modules serial port name in devices and printers.

This tutorial covers the Serial library. Connect to a Bluetooth Serial Device with XamarinAndroid April 27 2014 NET Android Bluetooth Hardware Xamarin. We are going to use the RFCOMM Bluetooth protocol for the communication between the Raspberry Pi and the Smart Phone.

The example below does it using an anonymous inner class. The COM port is something that exists only on the microcontroller not the Bluetooth device attached to it. Arduino Bluetooth Module Programming.

We will build a simple chat example which allows two connected devices to send text messages. A simple Android library for implementing Bluetooth Serial Port Profile SPP communication. The Bluetooth devices connection to the micro is via the TX and RX lines.

The Bluetooth device does not even know which COM port the microcontroller used to connect to it. This library allows you to connect with other Bluetooth devices using virtual serial ports RFCOMM. BL-819 or BL-830 Enter the Bluetooth Pairing PIN number.

Uses a callback to send data receive via bluetooth to your activity. Open SENA BTermSettingsBluetooth Management. This goes in yourAndroidManifestxml file.

After you have installed Android Studio you need to download this JAR file which contains the driver to access FTDI Serial devices. I have learned quite a bit about Bluetooth on Android and decided to write up a short description on how to. Now just select the Get Visible button to turn on your visibility.

In the Add COM Port dialog select the Outgoing your PC initiates the connection radio button.

The Bluetooth module Tx and Rx pins are connected with the Arduinos pin number 2 and pin number 3. Now what type in the textbox on the Android device will show up in the serial monitor window for the Arduino and what you type in the serial monitor window will show up on the Android device. Android Bluetooth Serial.

To run the app from Android studio open one of your projects activity files and click Run icon from the tool barIf your Bluetooth will not be turned on then it will ask your permission to enable the Bluetooth. Return to the Bluetooth Serial Terminal app and click on Refresh List. While the VCC and GND pins are connected with the Arduinos 5v and GND.

In the Arduino IDE choose serial port of Bluetooth module mine is COM10 Open the serial monitor as normal to view incoming information. Arduino and HC-05 Bluetooth Module Tutorial Android Smartphone Laptop Control - YouTube. In this case FTDI 232 chips.

You just need to implement the BluetoothSerialMessageHanler callback. After creating the new project it. Now open Android Studio lets begin by creating a new project.

First your app needs the BLUETOOTH and BLUETOOTH_ADMIN permissions. Blue2Serial is available on the jCenter repository.
