Android Bluetooth Example - Stack Overflow
Oct 02, · This version of android Bluetooth chat by using original google source code example of android Bluetooth chat. This is for easy understanding and quickly integrating Bluetooth capabilities in Jun 14, · Android provides a default Bluetooth stack that supports both Classic Bluetooth and Bluetooth Low Energy. Using Bluetooth, Android devices can create personal area networks to send and receive data with nearby Bluetooth devices. In Android and later, the Android Bluetooth stack provides the ability to implement Bluetooth Low Energy (BLE) You can base BluetoothChat example to send the data over. If you look at the code, text message string is converted to byte[] before being sent over bluetooth. So convert your data to byte[] and then send it over. – Win Myo Htet Nov 22 '13 at

Code plugins are a powerful feature of Bluetooth Developer Studio. The code plugin framework allows you to generate code based on the profile you are working on in the Profile Designer. The Generate Code window allows the user to choose a specific Plugin to use. This plugin will process the data and produce one or more output files.
Depending on the plugin, these output files can form the basis for your application or your Bluetooth hardware device, or implement the complete solution for client or server. We maintain a list of third-party plugins on our site. Go here to review and download the ones you like. To run a plugin that is already installed you must first load a Profile into the Profile Designer.
There are two types of plugin: Client and Server. Select an option from the Generate Code For drop down and the screen will filter the available plugins. In the dialog above, the two enumeration plugins will do just that: enumerate all the objects in your model. Next, choose a plugin by selecting it from the list. Then choose an output path by typing into the Save To box or by selecting Browse. Please note: your plugin can only reference files contained android bluetooth example code download this sandbox.
When you android bluetooth example code download selected a Plugin and specified an output path, you can choose Generate. This will load and execute the plugin and pass it the data that is loaded in the Profile Designer. The Plugin will then perform its actions and while doing so, the Code Generator window will show the progress.
If you would like the application to open the output location for you, select the Open output location when finished checkbox before selecting Finish. Installing a Plugin for Bluetooth Developer Studio assumes you have an already prepared Plugin. If not, see Developing a Plugin for more information on how to create one. Inside this folder, there will be a Plugins directory, which is where the application looks for plugins. Create a folder inside the Plugins directory and name it accordingly.
If you already have a prepared plugin inside a named folder, you can just copy the folder and its contents into the Plugins directory. The only required file for a Plugin to be recognized is a Plugin. js file. Either copy an existing Plugin.
js file subsequently modify it based on the guidance below or create a new file and name Plugin. js and add to it the GetInfo and RunPlugin methods described in the following section. Visit the Bluetooth SIG website here to access additional plugins developed by various partners, including chip, module and OEM suppliers. Plugins are JavaScript code files allowing you to implement behavior for both server and client on specific manufacturer chipsets and specific Bluetooth Smart Ready platforms like Android and iOS.
You can write your own plugins or use any valid plugins provided by Bluetooth partners and third parties. For Bluetooth Developer Studio to recognize a valid plugin, that plugin must provide two methods:.
The GetInfo method must set some properties on the supplied parameter. This parameter is mandatory. IncludeDefaultServices — Whether GAP and GATT services should be included even if they are not added to the project. Once you have modified the GetInfo method to provide the correct information for your plugin, save the file and re-launch Bluetooth Developer Studio. Now you can modify the RunPlugin method to execute the functionality you wish to provide in your Plugin.
NOTE: For a more detailed understanding of how the objects in the model associate with each other, please review the ENUMERATE ALL plugins for a detailed example. Note: FileManager is sandboxed. You can only read files from within the plugin directory, and you can only write to the output location.
For more details, see Calling the FileManager. This section describes some of the common tasks you may want to perform when writing a new plugin for Bluetooth Developer Studio. When implementing a Plugin, you pass in a PluginProfileData object as a parameter to the RunPlugin method. The PluginProfileData object looks like this:.
The ProfileData object also android bluetooth example code download a Services field. This field contains a list of Services defined in the Profile. You can iterate over the services with indexing using the following code.
As part of your Plugin you may wish to read files that you supply alongside your Plugin. For android bluetooth example code download You want to read a text file that contains a template of a file you want to produce as part of your output. You can read the file in and change the template parts with the data you are reading. The file must exist in the same folder as where the Plugin is installed.
Plugins are sandboxed and are unable to read files from outside of its installation folder. Bluetooth Developer Studio will generate source code that android bluetooth example code download be used on a device or by an application to connect to a device. The first parameter in the CreateFile method is the name of the file, android bluetooth example code download.
This will be created relative to android bluetooth example code download output location specified by the user. While your Plugin is executing you may want to output some information for the user to see as your plugin progresses, android bluetooth example code download.
Or similarly you may want to output the details of any errors that may occur. You can do this by calling the log method provided by the Plugin API. Anything that is passed to the log function will appear inside the Code Generator window and also appear in the log files provided by the application.
The code below iterates over the services within a profile and prints out the name of the Service to the log file. NOTE: There is currently no way to distinguish between an informative log entry and an error log entry. A future version will provide a way to specify the verbosity of the log entry. For example, a basic template that outputs all the properties inside the service characteristics:.
Hence, the template above would output something like this depending on the properties being considered :. If you want to add in a line break into your output you should add a carriage return newline combination i. There is no guarantee that a value may contain data so you should check if fields are null before you use them. The FileManager class has the following methods available that you can call:.
Please note: Attempting to read or write to a location outside of the sandbox is not allowed and will cause an error. This creates a file and populates it with the provided contents.
If the file already exists it will be overwritten. All plugins will be different and there are some cases where the output you wish to produce is in a complicated format, android bluetooth example code download. Bluetooth Developer Studio supports basic templating as a way to cut down on the amount of JavaScript code you need to write. This templating functionality provides a way for you to set up a template in a specific format and pass a data object to the template and have the response contain the information from the data in a way the template defines.
A simple example: we want to output a new line for every service and display the name and UUID of a service on each line. The sample below shows a complete working template file that achieves the above:. The template file above defines the format of the file we want to output and includes properties that we want to be replaced with information coming from the Profile within Bluetooth Developer Studio.
This template is expecting to receive the root object that is passed android bluetooth example code download RunPlugin method of your Plugin. We can then access properties from that object directly within the template. Using {{ProfileName}} android bluetooth example code download the same as accessing the ProfileName property of profiledata directly in JavaScript.
Now that you have a template file you should save the file in the same location as where you are developing your Plugin, android bluetooth example code download. Next, you can make use of the template by executing the ProcessTemplate method and pass in the template along with the data you want the template to use, android bluetooth example code download.
See the example code below. The above example takes the template file you created and runs it through the ProcessTemplate method, passing in the Profile object. It then creates a file with the data passed back from the ProcessTemplate method.
The object model for profiles, services etc. expose UUIDs at multiple points. You will need to validate the UUID format to check whether it is bit, bit or follows some other convention, android bluetooth example code download. In the Bluetooth spec these are defined in the characteristic. xml files. A PluginProfileBit contains a NameIndex and size field all as strings with an additional key value pair collection that also has an additional required field. Check the details of any exception or error messages that are displayed on screen when the plugin is generated.
The templating functionality of Plugins is a subset of the functionality provided by the Liquid templating framework. Liquid templating support comes via the dotliquid library. This is not exactly the same as Android bluetooth example code download itself.
For the full definition of the supported syntax, as well as differences between the liquid syntax in Bluetooth Developer Studio and Ruby Liquid, please see the dotliquid developer wiki, here.
Here are some key differences between the Bluetooth Developer Studio liquid implementation using dotliquidand Liquid itself. NOTE: This documentation is not exhaustive. Please share with us if you find any Liquid- or templating-related issues not described in this document.
To suppress the line break that would normally follow the end of a tag, android bluetooth example code download, you can use a hyphen "-" just before closing the tag.
