The blueooth packages are part of the OS (Raspbian) - they can be upgraded if a new version is released by the upstream Raspbian project and can be installed with the apt utility, or just choosing to update your OS packages from RetroPie-Setup when you do an upgrade.
Unfortunately, the fix suggestion that you provided didn't work in this situation. I have seen people online saying that they have used "alternative ps3 drivers" but not sure what these are or where they are to be found. Any other suggestions?
I'm having this exact same issue with ps3 controller. I went over to other thread to try and figure out own my on, but I'm very new to this and it is very hard to understand how to add the input.cfg.
I don't know where to even access that from. can you please help me and give some step by step guide?
You said you copy and paste a file? Can you please show me how to do that?
