Networking with LSL makes GUI crash, why?
Hello guys!
I have a problem to run OpenBCI_GUI. When I select to send packages through LSL, the GUI freezes and the following trace is shown:
...
LSL selected from Protocol Menu
openBCI_GUI: startButton was pressed...starting data transfer...
startRunning...
DEBUG: start data transfer

What is the correct sequence to perform the transmission via LSL? "Start Data Stream" -> "Start" LSL or the reverse? (same problem in two configs). I also set the print of the configuration screen:
I am on Linux Debian 9.0.
Thank you!
