Connection failed while using bluetoothAPI

[manojkumar.m]

Dear friends,

I am using JSR82 for bluetooth connection.

According to the application requirement,

I have to get the remote device address and have to connect to it send the data.

I am getting the bluetooth address of the remote device and getting the url of the remote device using
ServiceRecord.getConnectionURL(ServiceRecord.NOAUTHENTICATE_NOENCRYPT, false);

Here I am using uuid value as 0x0001.


I am getting the url as :
btl2cap://001dbec20fd0:1;authenticate=false;master=true


and when I am using this url to establish connection with remote device,

it is giving the exception as
BluetoothConnectionException:SymbianOS error = -5: General:

I dont know why I am getting this error.

so which uuid value I need to use to make a connection with remotedevice.

Actually I tested it on E61I device. and the remote device is MotorolaRazr. ( its service is btl2cap).

How do I need to do to make a connection with this device.
please help me.

and for the above application,
ServiceRecord.getConnectionURL(ServiceRecord.NOAUTHENTICATE_NOENCRYPT, false);

when I supply true as second arg to the above function,

I opened a connection like:
StreamConnection conn = (StreamConnection)Connector.open(url);

then it is giving an exception as
java.lang.IllegalArgumentException.


I dont know why it is giving like this. For the Connector.open() function, I am supplying the arg as output of
sr.getConnectionURL(ServiceRecord.NOAUTHENTICATE_NOENCRYPT, false);


its urgent. please help me.

Hi sowmitri,

I am sorry to say that I cant help you in that particular task ( sending file from mobile to pc using bluetooth) because I never tried that. I can help you from mobile to mobile.

manojkumar_m and sowmithrii, does this discussion help?

By the way if you are new to J2ME, MIDlets and Bluetooth, I recommend to start with a book or tutorials rather than code examples as you will have to debug a lot on your own. There are a lot of bugs, tweaks and lessons to be learnt. Bluetooth is complicated. I do not have a good J2ME book at hand right now, however, start with the references of this one for JSR-82 (perhaps your library has its previous edition) or read at least the PDF coming with the specification. If you like to start with tutorials, continue here…
