Cannot connect via Putty

[averri]

I have upgraded the GPy firmware using the Expansion Board 3.0. After the upgrade, I can see the led blinking, but I cannot connect to the board using Putty. I'm using the correct port showed in the Device Manager on Windows 10, and the baud rate of 115200. The Putty screen remains black, no messages are printed.

@averri In Putty settings you should set flow control to None
