Problem with bluetooth

[pablovara]

Hello experts:

I made a program in j2me for my nokia 6630 using the bluetooth API for communicate two phones and send phrases like a chat, but when i try the program in the phone i have a problem that in the emulator i did not have.

This problem is "Symbian OS error:-44" and i check that it is in the next line:
if (!localDevice.setDiscoverable(DiscoveryAgent.GIAC)) {
throw new IOException("Can't set discoverable mode...");}

I dont know how solve it and neither the reason why it happens.

Thank you very much your help. Bye.

Thank you very much for your help peterblazejewicz.

1. I have the bluetooth tool switched on when i try the program.
2. I never try any other bluetooth program in my phone.

In your phone model, it is not possible to change Bluetooth visibility from within a MIDlet.

Thank you Traud, but one more question:

If I could not change the visibility with the MIDlet, can I eliminate the next line of my program, having the same funcionality??

if (!localDevice.setDiscoverable(DiscoveryAgent.GIAC)) {
throw new IOException("Can't set discoverable mode...");}

Bye.
