Where are bluetooth MAC addresses and other such configs stored?

My WiiU controller always connected great until I updated RetroPie + kernel the other day. But now every time I boot up ES I have to go to Bluetooth settings and tell it to connect to all registered devices (while pressing buttons on my controller) to get it linked up. That's my main problem in case you have any tips for me, but I'm trying to solve this thing on my own, so I'm trying to purge my system of all trace of the controller to start fresh.

I deleted all mentions of that controller in es_input.cfg and es_temporaryinput.cfg.

I checked bluetooth.cfg (in configs/all) and the only thing it said was 'connect_mode="default"', so I left that there.

Where are the other bluetooth options/configs stored? Like MAC addresses and security modes and udev rules all that?

@brimby The associations are stored in /var/lib/bluetooth, but you can use the Bluetooth menu from the RetroPie setup and 'forget' all registered controllers.

@mitu Thank you! Do you happen to know which scripts are directly responsible for "keeping an eye out" for incoming bluetooth connections? I feel like maybe something got overwritten on mine when I updated. I only suggest this because, after I updated, my snes/retroarch.cfg got a bunch of overrides written in it that weren't there before. So I'm wondering if the same thing happened to one of the files responsible for bluetooth configuration. To reiterate, I can connect my WiiU controller fine if I manually go to bluetooth settings in the GUI and tell it to connect to all registered devices, but I used to be able to just turn on my controller and autoconnect, which I greatly miss being able to do. Thanks again.

I don't think RetroPie has it's own handling of registered devices, it just relies on the OS (Linux) for the available/registered devices. You might be stumbling upon a bug in recent Linux kernels - see the 1st pinned topic in this category.
Re-register the Wii U controller, without any special connection mode selected, and see if it re-connects automatically on power on.

@mitu I had already tried de/re-registering the controller multiple times to no avail. But I'm going to run that firmware downgrade mentioned in the sticky, and if it fixes things I'll post in the sticky about my experience so that people will know if it affects WiiU controllers too.
