Connect two Wiimote-Controller

[Leon0402]

Hello everyone,

I followed the tutorial https://retropie.org.uk/docs/Wiimote-Controller/ on how to set up Wiimote-Controllers. I used his shellscript:

#!/bin/bash
sleep 1 # Wait until Bluetooth services are fully initialized
hcitool dev | grep hci >/dev/null
if test $? -eq 0 ; then
    wminput -d -c  /home/pi/mywminput 00:19:1D:92:90:38 &
    wminput -d -c  /home/pi/mywminput 00:19:1D:84:EF:33 &
else
    echo "Blue-tooth adapter not present!"
    exit 1
fi

Of course I used different mac addresses. The problem is that I can pair both controllers, but not at the same time. The reason for this might be that as soon as one controller is connected, my computer cannot pair with another bluetooth device.
If I'm already connected with one controller and try to connect with another one (through the script or manually) I get a socket connection error. As soon as I disconnect the bluetooth connection, I can pair again.

Dolphin says this " Do not pair the Wii Remote to your computer through its native Bluetooth settings." in their docs. This sounds to me like my computer is not allowed to actually pair with the controller the way it does it now. As if there is any trick making it possible to connect actually with two bluetooth devices.

I am running retropie on my computer on debian.

Thanks in advance!
