Like, any sample codes or tutorial/ procedure/instructions will be very helpful. The Bluetooth implementation automatically creates a service record when your application creates a connection notifier, either a StreamConnectionNotifier or an L2CAPConnectionNotifier. This class allows the client to initiate and cancel device and service discovery. The Bluetooth Manager is a set of java APIs which is designed to streamline all the hard work of dealing with unstable by its nature Bluetooth protocol. MIDlets can thus use the PushRegistry class to set themselves up to be launched automatically, without user initiation, if the underlying implementation supports push operations. To debug the sample and then run it, press F5 or select Debug > Start Debugging. The relay is a Normally Open (NO) device, so the contacts at pins 7 and 8 are not connected until the relay is activated.

This samples shows how to: Initialize and publish a custom service/characteristic . sure to unzip everything to access shared dependencies. Handling L2CAP connections is more involved than handling stream connections; developers must deal with maximum message sizes ( maximum transmission unit, or MTU), and with breaking up and reassembling long messages. Java Code Examples for javax.bluetooth.DiscoveryListener. I have been unable to find any Java library to . Press F6 or use Build > Build Solution to build the sample. There are two categories of hardware requirements: the requirements of the Java ME device and the requirements of the Bluetooth subsystem in the device. To retrieve already known or cached devices the client calls the DiscoveryAgent method retrieveDevices(): RemoteDevice[] retrieveDevices (int option); The client initiates a device discovery cycle by calling startInquiry(): boolean startInquiry (int accessCode, DiscoveryListener listener); To receive discovery notifications from the DiscoveryAgent the client application must implement the DiscoveryListener interface and its four discovery callbacks deviceDiscovered(), inquiryCompleted(), servicesDiscovered(), and serviceSearchCompleted(), as illustrated in this sample class: The helper method btInitiateDeviceSearch(), which can be called in response to a user request, retrieves any cached or previously found devices, then kicks off an inquiry: Let's take a more detailed look at two callbacks the DiscoveryAgent invokes, and see how the client should process discovered devices: Once nearby devices have been discovered, the client can search for services of interest.
