Can you connect Ganglion board to PC/MAC using wires?
Will it have any benefits (faster rates - more data)?
In any case I want to test it - if not for the fact that currently brainflow is super buggy when connection is lost (it just hangs).
So I would like to know if it's possible?
I have Arduino Uno - I can wire it up to that I guess - but what I need to wire?

No.
No - why?
Isn't this open source - can you explain why your answer is so firm?

There is no support for wired connection in the Ganglion firmware. Yes, you could rewrite that firmware. But not recommended as it will likely preclude using the Ganglion with the OpenBCI_GUI, and make contact with customer support more difficult. As troubleshooting for customer support would be challenging without their ability to duplicate your situation.
If you have Brainflow issues, please join the Slack. Andrey the developer of Brainflow answers questions quickly. There is likely a way to detect if radio connection drops.

Yo - you got customer support - you guys are so cool!
You can email customer support at (contact at openbci.com). This OpenBCI Forum is not the same as customer support.
Ah ok.
Well I'm not doing anything commercial (where it's risky to break things).
If the GUI currently detects broken Ganglion radio connection, that means there is some workaround to determine this yourself with your own calls on Brainflow.
Regardless - but I just checked out the code:
https://github.com/OpenBCI/OpenBCI_Ganglion_Library/blob/master/OpenBCI_Ganglion_Library.cpp#L982
It seems that I only need to connect the rx/tx pins in this picture:

And I'm potentially good to go.
@wjcroft So the breakout pins connect directly to the SPI of the biosensing chip, right?
The Simblee microcontroller / cpu on the Ganglion is acting as SPI bus master. Only one master per SPI bus.
