Failed to start data stream when BDF+ selected and Brainflow File

DashBarkHuss · September 27

If use these settings where I'm using BFD+ with Brainflow File:

I get this error when I click Start Data Stream

Failed to start data stream. Please check hardware. See console Log of BrainFlow Log for more details.

If I change the setting to Brainflow Network (from File), the issue goes away.
Is this expected behavior?

It also happens on Dr. Konkoly's computer.
