Failure at gdx.read() at Python examples

[duodenum96]

Hello,

While trying to run the gdx_getting_started_usb.py with select_sensor([1]) and start(50) arguments, I get the following error:

Traceback (most recent call last):

File "C:\Users\user\Desktop\brain_stuff\josh\godirect-examples-main\python\gdx_getting_started_usb.py", line 36, in
measurements = gdx.read()

File "C:\Users\user\Desktop\brain_stuff\josh\godirect-examples-main\python\gdx\gdx.py", line 302, in read
if gdx.devices[i].read():

File "C:\Users\user\miniconda3\envs\hipokrat\lib\site-packages\godirect\device.py", line 181, in read
return self._GDX_read_measurement(timeout)

File "C:\Users\user\miniconda3\envs\hipokrat\lib\site-packages\godirect\device.py", line 401, in _GDX_read_measurement
return self._GDX_handle_measurement(response)

File "C:\Users\user\miniconda3\envs\hipokrat\lib\site-packages\godirect\device.py", line 416, in _GDX_handle_measurement
sensors = self._get_sensors_with_mask(sensor_mask)

File "C:\Users\user\miniconda3\envs\hipokrat\lib\site-packages\godirect\device.py", line 272, in _get_sensors_with_mask
sensors[i] = self._sensors[i]

KeyError: 2

Does anyone have any idea related to the reason of this?

Hello,

What happens when you run the example program without adding the arguments to select_sensor() and start()? It should provide you with a list of sensors to choose in the console, as well as allowing you to set the sampling period in the console. Can you choose a single sensor and set the sampling period in the console and run the program without the errror?
