Reply To: Tutorial: RetroPie with DualShock 4 and Bluetooth

[exonerated]

Hmmm. I previously had a PS3 controller synced with bluetooth. I try to remove that because it is the only bluetooth device displayed in hciconfig. Could this be the problem? Having a PS3 controller synced before? I try to remove it and get hit with this:

pi@raspberrypi ~ $ bluez-simple-agent hci0 00:02:72:D6:9E:96 remove

I can’t remove the PS3 connection. Anyway to remove it completely and do a clean install of the DS4?

Here is what hciconfig outputs (This is my PS3 controller MAC which I no longer have, not my DS4 MAC):

pi@raspberrypi ~ $ hciconfig
