Hi all,

I wrote a Python script to listen to the socket where the P3Speller would write its output. I edited the matrix to be a 3x3 one with these associations:

( Dispaly, Enter )
1 ( , 0 )
2 ( Avanti, avanti )
3 ( , 0 )
4 ( Girasx, girasx)
5 ( , 0 )
6 ( Giradx, giradx )
7 ( , 0 )
8 ( Indietro, indietro )
9 ( , 0 )

I ran a session with mouse click selection. The script listened to the socket for 30 seconds but, despite 4 successful selections, not a single "P3Speller_Output"-type output was written in the socket. Instead I found in the log file of my script output of this form:

Running 1

Recording 1

SourceTime 483

StimulusTime 491

The summary written by P3Speller at the end of the session reports correctly the 4 selections.

Where am I wrong? ^^'

It seems you are reading from the UDP port used by the AppConnector to write its data to.
You should make sure that the P3Speller uses a different UDP port than the one specified in the ConnectorOutput parameter.

Thank you very much! It helped a lot!
