I expected this to work out of the box but it does not work well at all. Once the pairing is completed, if I try to connect it it doesn't stay connected. I have checked the dmesg and apparently there is a buffer overflow somewhere. I can pair a bluetooth headset to my laptop and the Dualshock4 pairs with my samsung tablet without problems but when I try to pair the dualshock4 to the laptop, running Ubuntu 19.10, it does not work.
