Connect fail to the board in the GUI
Opened this issue · 4 comments
Hi everyone!
I can't connect the software to the board on GUI mode. When I click on the "Connect Board" buttom, the follow message show on the terminal:
$ python openbci_lsl.py
Detecting board settings...
/dev/ttyUSB0 False-------INSTANTIATING BOARD-------
Connecting to V3 at port /dev/ttyUSB0
Traceback (most recent call last):
File "/home/rhubner/BCI/OpenBCI_LSL/lib/gui.py", line 298, in connect_board
self.lsl.board.disconnect() #close the serial
AttributeError: 'StreamerLSL' object has no attribute 'board'
The configuration in the GUI seems correct. My port is /usb/ttyUSB0 and daisy is set to 'false'.
The error showed doesn't related to the 'self.lsl.initialize_board(port=port,daisy=daisy)', but the line 298 (self.lsl.board.disconnect() #close the serial). So, I couldn't understand why the 'initialize_board' fail and why the object 'self.lsl' lost the reference.
294 try:
295 self.lsl.initialize_board(port=port,daisy=daisy)
296 except:
297 self.lsl.board.disconnect() #close the serial
298 self.console.setText(" Error connecting to the board")
299 print("Error connecting to the board")
300 return
Which did you enter in the "Port" field - "/dev/ttyUSB0" or "/usb/ttyUSB0"? Double check to make sure that the port you're entering is the correct one. I was able to recreate your error when I typed the wrong port into the GUI.
Otherwise, could you check if the program works for you in Command Line mode? Type python openbci_lsl.py --stream to check.
I realize that the try/except statement is a little problematic in this bit of code, thanks for bringing that to my attention.
I review this yesterday...
The command python openbci_lsl.py --stream works fine. I think the problem occurred only GUI interface.
The error appears because the object "port" is a <class 'PyQt4.QtCore.QString'>. I changed it to <type 'str'> and solve it, but I got another problem... The object "self.outlet_eeg" isn't found in the "send" method at the streamerlsl.py.
I think when you're going pass the "self.send" method to run in the thread, the "self" member is missing references...
Look my trace:

bump. i have exactly the same problem. has there been any solution?
Hello @alt0xFF
This problem is only the first!
I've been trying to fix all the problems until it was possible to execute ...
But finally, at the time of execution, the graphics do not appear... Then I gave up! There are also many problems with style, etc. I think this module has been abandoned!
