The connection implementation for btspp cannot be found

[Xavier Sarsanedas Trias]

Hi everyone!

I'm developing a project where I'm communicating between an Android mobile
and a computer with ArchLinux ARM Operating System. The objective is having
a serial channel to be able to communicate between this devices.

This project worked me fine. But now, I have had to update the ArchLinux
system and now I have problems with bluetooth communication.

I developed a java program that use BlueCove version 2.1.1-SNAPSHOT.
The problem appears when I try to run the program. The error occurs when
the program executes the bold line code:

LocalDevice bluetoothUMBER = null;
StreamConnectionNotifier connexioNotificador = null;
StreamConnection fluxConnexio = null;

try {
bluetoothUMBER = LocalDevice.getLocalDevice();

bluetoothUMBER.setDiscoverable(DiscoveryAgent.GIAC);
*connexioNotificador = (StreamConnectionNotifier)
Connector.open(URL_SERVEI);*

//THIS IS THE CONTENT OF URL_SERVEI -->
btspp://localhost:0000110100001000800000805f9b34fb;name=RemoteControl

And the error that shows is:

BlueCove version 2.1.1-SNAPSHOT on bluez
[ERROR]: The connection implementation for btspp cannot be found.
javax.microedition.io.ConnectionNotFoundException: The connection
implementation for btspp cannot be found.

BlueCove stack shutdown completed


I'm not sure where is the problem. What does it mean this error?

Before update the system I used the bluez 4, and now I see that the bluez
is updated at bluez 5.24

Perhaps Bluecove 2.1.1 isn't compatible with bluez 5.24?
I'm leaving something important to configure?

Thank you!
