add the call to BluetoothAdapter.SetContext(this) in the onCreate method of the activity.add the btsim.jar to the libraries of the project.add the necessary permissions for the bluetooth AND for internet access (required by the bt simulator).My preferred workflow, at this point, is: Then you can create a new android project. You need to install the application because it will handle the system activities of the bluetooth, like switching on/off the radio and start a discovery. there is an already precompiled jar in dist, execute java -jar btsimserver.jar -help to see some options (if you don't have the adb command in your path, you will need to set the adb.path variable).The jar library is provided as convenience in the dist-shared directory The application need all of them, but for the library jar you just need to compile the main one ( src). there are 3 source directories, src, src-sysactivities and src-testapp.a precompiled version of the application is provided in the dist directory.compile and install into at least 2 android emulators the android-bt-simulator application.call BluetoothAdapter.SetContext(this) at some point (the onCreate method is fine) in your activity/service.There is a slight modification to the code, in order to use the simulator: What you need to do in order to use the simulator instead of the android API, is to change the import from android.bluetooth to dk. (and also add the INTERNET permission in the android manifest file). It's a tcp-based implementation of part of the android bluetooth API.Īs for now, you can communicate between different emulators using the RFComm protocol, you can start a discovery phase and enable/disable the bluetooth.
