Dual 8Bitdo Bluetooth controllers

[stahl80]

Hi.
In my setup i have dual 8bitdo bluetooth controllers. With retro pie 3.... i never had any issue with that. But now after updating to the latest retropie 4 (clean install) I'm having issues using both controllers. If i have one connected everything is fine. But is i connect both (yes both a connecting fine) and trying to play Tekken 3 for example some functions stops working. start + slelect won't exit the emulator and on one controller A,B, X & Y does nothing. But with one controller connected all those functions are there. I can see when starting an emulator it sees two connected controllers on different "ports".

Any help would be appreciated!

Thanks!

In $ cd /opt/retropie/configs/all/retroarch-joypads I have one file named 8BitdoNES30Pro.cfg

And the content of that file is:

input_device = "8Bitdo NES30 Pro"

Hi,

I had a similar problem to the one you described here. The problem I found is that I had one older 8bitdo controller a new one. The old when had older firmware (v 2.7). Once I upgraded the firmware to version 3.x and followed the retropie 8bitdo guide everything worked fine.
