I'm developing a bluetooth messaging application which sends text messages between devices.
My problem is when I connect more than 2 devices. After sending some data between them (let us say 3 devices) I get this exception:
javax.bluetooth.BluetoothStateException: too mach concurent requests
at com.sun.kvem.jsr082.bluetooth.ServiceSearcher.start(ServiceSearcher.java:67)
at com.sun.kvem.jsr082.bluetooth.DiscoveryAgentImpl.searchServices(DiscoveryAgentImpl.java:226)
at javax.bluetooth.DiscoveryAgent.searchServices(DiscoveryAgent.java:259)
at BSearch.deviceDiscovered(BSearch.java:78)
at com.sun.kvem.jsr082.impl.bluetooth.BTDeviceDiscoverer.run(+268)
requests.
I get it at device inquiry... this means when the application tries to detect other devices.
This is the function that starts the inquiry:
public void startSearching() throws BluetoothStateException{
System.out.println("before inquiry");
LocalDevice localD = LocalDevice.getLocalDevice();
try
{
DiscoveryAgent discoveryA = localD.getDiscoveryAgent();
discoveryA.startInquiry(DiscoveryAgent.GIAC,this);//////
}catch(BluetoothStateException bse){
}
isSearching = true;
System.out.println("dupa inquiry -- waiting");
}
This is the function that restarts the inquiry after 4 seconds:
public void serviceSearchCompleted(int transID, int respCode) {////////////////////////////////////////
pendingSearches--;
if(!isSearching && pendingSearches==0)
refreshServList();
try { Thread.sleep(4000); }
catch (InterruptedException ie) {}
if (isRunning == true)
try {
System.out.println("CONTINUAM CU CAUTAREA");
startSearching();//////
} catch (BluetoothStateException ex) {
ex.printStackTrace();
}
}
The class implemets a DiscoveryListener and when I call 'startSearching()' the thread is stoped then started again.
My application searches for devices every 4 seconds (in a separate thread) and after that updates a List with the names of available devices in the area.
Please someone help on this exception... at least give me a
good hint because I couldn't find the solution anywhere. Thanks.
