[Solved] Can I pair a PS4 Dualshock controller with two Pi 4s?
-
Oh. I guess it needs to be written more like this.
bluetoothctl remove 40:1B:5F:BA:D5:A0 bluetoothctl scan on sleep 5 bluetoothctl scan off bluetoothctl connect 40:1B:5F:BA:D5:A0 bluetoothctl trust 40:1B:5F:BA:D5:A0When running that as an executable in Emulation Station, it just hangs in Discovery Mode and doesn't progress any further.
Sorry, I don't know how to code.
Any help at all please?
-
Do you need to do the scan on/ off though? since you already know the device you want to pair with, seems unnecessary
-
Yeah.
Say for example, my controller is currently paired with my PlayStation 4.
I'm just trying to easily switch it over to the Raspberry Pi.
It's not at easy as one would think. :)

Oh. Sorry.
Yeah, the controller is already a registered device on the Pi.
It won't connect though, with any commands that I know of, unless I delete it and rescan the controller again for some reason.

according to this article:
https://www.linux-magazine.com/Issues/2017/197/Command-Line-bluetoothctl14. trust <DEVICE-MAC-ADDRESS>
Sets the device to re-pair automatically when it is turned on, which eliminates the need to pair all over again.I would just try this:
bluetoothctl trust 40:1B:5F:BA:D5:A0
By itself, if that doesnt work, then maybe:
bluetoothctl remove 40:1B:5F:BA:D5:A0
sleep 5 (you might not need this, not sure, test with and without)
bluetoothctl connect 40:1B:5F:BA:D5:A0
bluetoothctl pair 40:1B:5F:BA:D5:A0 -
It's already trusted.
So my Dualshock controller is currently paired with my Playstation 4.
I would now like to connect it to my Pi 4 that it already knows and remembers.
pi@retropie:~ $ bluetoothctl paired-devices Device 40:1B:5F:BA:D5:A0 Wireless Controller pi@retropie:~ $ bluetoothctl pair 40:1B:5F:BA:D5:A0 Attempting to pair with 40:1B:5F:BA:D5:A0 Failed to pair: org.bluez.Error.AlreadyExists pi@retropie:~ $ bluetoothctl connect 40:1B:5F:BA:D5:A0 Attempting to connect to 40:1B:5F:BA:D5:A0 [CHG] Device 40:1B:5F:BA:D5:A0 Connected: yes Failed to connect: org.bluez.Error.FailedWould deleting the file org.bluez.Error.AlreadyExists help any before trying to pair the controller back again with the Pi 4?
I'm asking since I don't want to delete anything and possibly make it all worse.

bluetoothctl pair 40:1B:5F:BA:D5:A0Once that MAC address is removed, it's no longer available until you scan on again.
Unless there's some special command to add it back which I haven't found.
Nice idea though. :)

I don't think that's a file - I think you should remove the device before attempting pairing it again.

Finally got it! :D
I have this as an executable file under Ports in Emulation Station.
bluetoothctl remove 40:1B:5F:BA:D5:A0 timeout 10 bluetoothctl scan on bluetoothctl scan off bluetoothctl connect 40:1B:5F:BA:D5:A0 bluetoothctl trust 40:1B:5F:BA:D5:A0Last question and I'll be all done.
Where can I insert these commands when Emulation Station begins to load?
I only need for it to run just once when the Pi is initially turned on.
Please and thank you.

EmulationStation is loaded fro the
autostart.shscript - https://retropie.org.uk/docs/FAQ/#how-do-i-boot-to-the-desktop-or-kodi. -
Thank you so much!
End result:
/opt/retropie/configs/all/autostart.sh
sudo bluetoothctl remove 40:1B:5F:BA:D5:A0 sudo timeout 6 bluetoothctl scan on sudo bluetoothctl connect 40:1B:5F:BA:D5:A0 sudo bluetoothctl trust 40:1B:5F:BA:D5:A0 emulationstation #autoNow I can easily pair my controller back to the Pi on system startup without even having to plug it in using USB and navigating through all of the menu options.
So happy! :)
