Periodically discovering Bluetooth

[razebond86]

Hi to all..

I'm developing a application, that searching a particular device via bluetooth. If the device found, then i'll do the process. If the device not present, then the application 'll do another process. So i want to start bluetooh discovery mode periodically. Any replay 'll appreciated.

Thanks
Raz

Do this Search discovery of available bluetooth devices in a worker thread in a Do while(true) loop and after every search, make this thread sleep for the interval of time after which you want to search again.

Thanks for your replay ekta..

Here, could you please tel which part of the code want to write inside the thread. Did you tried with thread. Can we create the discoveryAgent again and again?

Another approach:

Use javax.bluetooth.DiscoveryAgent.startInquiry(int accessCode,
DiscoveryListener listener);

see Interface DiscoveryListener API methods
void deviceDiscovered(RemoteDevice btDevice, DeviceClass cod)
Called when a device is found during an inquiry.
void inquiryCompleted(int discType)
Called when an inquiry is completed.

When the Inquiry is Completed you get a callback in inquiryCompleted(int discType) where you can sleep for predefined time using a Thread and then startInquiry() again.

In deviceDiscovered is called back, everytime it finds a new device, do what processing you need to do.

deviceDiscovered

public void deviceDiscovered(RemoteDevice btDevice,
DeviceClass cod)
Called when a device is found during an inquiry. An inquiry searches for devices that are discoverable. The same device may be returned multiple times.
Parameters:
btDevice - the device that was found during the inquiry
cod - the service classes, major device class, and minor device class of the remote device
