Also, something is broken on the cyton daisy board, probably the bluetooth module(bluetooth is not working) and that is why I am using WiFi board. @wjcroft @retiutut

I am not exactly sure, but they ordered the whole set of OpenBCI (wifi, bluetooth, etc) atleast 3-4 years back. It was ordered by university and I am using it now in the Robotics lab

re: dongle. Yes, if your computer has built-in Bluetooth, it should work without the dongle. Although the dongle is inexpensive and allows support of older computers / operating systems.

Another question I have is if I got the Ganglion, would I still need the dongle if my computer supports Bluetooth 4.2?

the firmware will not send EEG data over the Bluetooth radios."

I've seen that the max sampling rate is 250 Hz over Bluetooth, but over WiFi, it can go as high as 16kHz. Is it possible, then, for us to disable Bluetooth, and instead save our data to an SD card sam

Unfortunately the Ganglion wireless data stream (via Bluetooth), is already at capacity. In fact the 4 channels of data are already highly compressed just to fit in the available bandwidth. See:

Modify the source code to sync via bluetooth different data streams (ganglion + IMU's). This is probably a much difficult and complex project.

Then you are NOT using Wifi Shield, but the original Bluetooth-Gazelle radio protocols. So that makes the spikes you are seeing even more unexplainable. Many of the clone makers are shipping nested bo

Yoosung is trying to decode the Bluetooth data stream bytes.

Actually the BEST way to decode the stream is to use the Brainflow library. Decoding it by yourself may lead to errors and is not recommended. Additionally, the Brainflow method allows you to talk to

Yes, you can use the native Bluetooth on newer Macs. The OpenBCI_GUI uses Brainflow library under the hood. Brainflow supports TWO device classes for Ganglion. 'Ganglion', which uses the dongle serial

Is it possible to use the builtin Bluetooth in my Mac instead of the USB dongle?

I'm receiving raw data values directly via bluetooth.

Although my audio outputs/inputs have not changed since I last had the GUI working, I currently am using Bluetooth headphones (Sony WH-1000XM4) as output and sometimes also input (I also have Microsof

If you have an authentic Cyton, it comes with a USB dongle, that allows a "Bluetooth-like" connection between the Cyton and dongle. Thus you do not need to use the unreliable Shield, and you

Are you saying that the data stream interruption ONLY happens within your booth? This might indicate that the Bluetooth reception is compromised between the Cyton and the dongle. Although the Daisy sh

The BCI data that flows locally over the Bluetooth connection is not explicitly encrypted. But you could easily encrypt the data stream yourself using the Brainflow library to read the stream and appl
