In any event, this is completely weird, and again, a symptom of something odd going on with the LSL stream. Your best bet is to use the Matlab binding for Brainflow, to directly read the samples from

issue. But instead some lossage is happening via LSL or Matlab. Suggest you stream directly using Brainflow+Matlab calls and avoid using LSL and GUI entirely.

I'm using Cyton board to do surface EMG study. I stream my data via LSL to MATLAB with the sample code provided here. The streaming works well for the channels, but the recorded time gave me negative

Your best bet is to just use the LSL stream provided by the HackEEG hardware. For example with OpenViBE or other LSL friendly app.

Hello, thank you for everyone's assistance so far. Right now, I decided to settle using LSL to stream data from the OpenBCI GUI to Unity (i.e. the concentration/relaxation state), and I'm able to get

For external triggers, can I use LSL to label the data, and if it can work, need i to input the LSL library to Cyton board?

You may still be able to use the 'fork' he made of the GUI. But since it is so badly out of date, lower your expectations. LSL input was never a feature implemented in the OpenBCI maintained GUI.

Thank you for your suggestions. I selected OPENBCI because the GUI is very friendly. I will try other LSL programs later.

Since he mentions that his device can output LSL, there are MANY other LSL compatible programs that could display your data. Such as OpenViBE, etc.

No, that is not true. LSL is still available in the Networking Widget. See documentation for that widget.

I am also looking into the LSL in OPENBCI, which is used to stream data to other software.

Right now I'm directly streaming the data from my Cyton to Unity using Brainflow, but indeed I'm still rather lost on the signal quality validation within the Unity proper. I checked the documentation

that I can send the filtered data via an OSC/UDP/LSL/Serial connection, but I was wondering if it would be possible using bluetooth.

We designed a classifier to recognise some EEG actives useing the saved data files, and we successfully connected between openbci GUI and MATLAB using LSL, the data appears on the run time on the Comm

OpenBCI_GUI can stream out LSL, and you can also directly stream from OpenBCI boards to LSL.

We have completely refactored the Networking widget with GUI v5.2.1. This resolves nearly all issues with streaming out TimeSeries data over UDP, LSL, and OSC. We were seeing issues with multiple Java

Try GUI 5.2.1 and UDP or LSL. We've done a major refactor of the Networking Widget.

If all else fails, it also appears that I could set up the OpenBCI GUI with the above settings, then stream via LSL to OpenVibe.
