Start the streaming works fine. $ muselsl stream --ppg Searching for Muses, this may take up to 10 seconds... Found device Muse-XXXX, MAC Address 00:55:DA:B5:06:XX Connecting to Muse-XXXX : 00:55:DA:B5:06:XX... Connected. Streaming EEG PPG...

But whenever try to record PPG, it cannot find the stream.

record --type PPG Looking for a PPG stream... Can't find PPG stream.

--type EEG just works fine. record --type EEG Looking for a EEG stream... Started acquiring data. Looking for a Markers stream... Can't find Markers stream. Start recording at time t=1558332757.922 Time correction: -1.2806500308215618e-05 Time correction: -1.7711998225422576e-05 Done

I changed slightly csl, view, viewer_2 following stepheninx, but still cannot find PPG stream. It seems broadcasting shows 'Streaming EEG PPG...' but not actually streaming PPG.

Can you report which OS and which version of Python you're using.

Also, could you trying adding the --disable-eeg flag to muselsl stream --ppg and see if you are able to record from a PPG stream then?

@jdpigeon Hi, I just tested and confirmed it works when use --disable-eeg. but when the EEG stream starts together, muselsl cannot find PPG stream.
