I can’t give you any information about Bluetooth. I tried again connecting it via Bluetooth, it’s still not working. It shows up in Windows, but not in intiface. I have no idea what is wrong there and why it’s not showing up. But @Falafel 's review covers it.
I enabled serial connection, but how do I connect it? Under what name is the SR1 in “Protocol Type”? And what do I need to full in the other entries Port Name, Baud, Data Bits, Parity and StopBits? I used the same numbers as it shows in Multifunplayer, but it’s not working.
