Cannot view when streaming PPG ACC GYRO #161

Open danielemarinazzo opened 3 years ago

danielemarinazzo commented 3 years ago

Hi

I am on Ubuntu 18.04.

When I just stream EEG, I can correctly view it in another terminal.

If on the other hand I stream also PPG, AAG, and GYRO, I get

Streaming EEG PPG ACC GYRO... but when I run muselsl view on the other terminal I get

Looking for an EEG stream...

Are you sure the stream was running while you started the view command? If you are sure the stream wasn't closed accidentally, try increasing the timeout. I've had an instance of this error when for some reason it took the resolve_byprop() function call longer than usual to resolve the stream.
