reading Ganglion BLED112 dongle on OS serial port

Friends,
Apologize in advance as it may be a silly question.
My understanding is that Ganglion transmits/receives data to PC (openBCI GUI) via Bluetooth BLE Dongle that is corrected to serial port (in my case COM3).
Can I read data from serial port directly (using any serial port monitor program or with my own program)? Or is it mandatory to use openBCI GUI to stream? If it is mandatory, then I am trying to understand the reason why normal serial port reader programs not even detecting raw data on the serial port?
thanks
Shanti Kumar

Shanti, hi.
The Ganglion uses a BLED112 usb serial port dongle. This dongle is unusual, in that it speaks Bluetooth on the radio side, but usb serial COM port on the other. Thus the serial stream is highly technical and geared towards Bluetooth communications API.
What you are looking for is the Brainflow library and examples. This can receive from Ganglion without the GUI. And in fact the GUI uses this same library to talk to the Ganglion.

Hi William,
Thank you so much for the information. I will try with Brainflow libraries.

Hello, @shantikumar, I've been having the same issue related to you question. Have you gained any new insight on this matter?
@lugabiel, hi.
You need to use Brainflow library to talk to the BLED112 dongle. See above links.
