Pairing Dualshock 4 (PS4) controllers on the same Pi but with 2 differend SD cards
I have one Raspberry Pi 3 Model B+. With that Pi I use 2 SD cards one 32 GB Recalbox image "burned" to it and one 64 GB Retropi image "burned" to it.
I paired my 2 Dualshock 4 wireless controllers via Bluetooth in Recalbox (I had to do it in bash with bluetoothctl - see https://github.com/recalbox/recalbox-os/wiki/Connect-bluetooth-controller-manually-(EN)#user-content-using-bluetoothctl). Everything works great. If I reboot they repair themselves and all is good.
Then I switched SD cards and started my 64 GB one (with Retropie). This card is an all Playstation image and I can pair the controllers OK without any "hacks". If I reboot they repair themselves and all is good.
When I switch back to the 32 GB card with Recalbox the controllers can't pair anymore.
Can't I use my controllers with 2 images?
@oak-leaves no, just as you couldn't use your controller with two different playstations, pairing means what it means and it is saved on sd.
you must reset your controller and repair them everytime you change sd
Ahhh :( I'm somewhat new to Bluetooth... The only other Bluetooth stuff I have are portable speaker / headphones and I can pair them with many devices (but can only use with one at the time) and I don't have to configure each time.
@oak-leaves yes there are several mode of bluetooth synchronisation
