@exatropix If BRLTTY is selectable in NVDA's list of braille displays, this means the BRLTTY API is running, otherwise it would not show up as a selection. Please check the following:

• Do you see more than one brltty.exe process in Windows Task Manager? If so, multiple instances are somehow active. Exit them all and start just one
• Does BRLTTY show the startup message to the display? If not, the connection between the display and BRLTTY might not work and you need to fix that first
• A log from the BRLTTY side might also be helpful here besides the NVDA logs, could you please post those to this issue so we can investigate further?
