Bluetooth failed / Permission Denied

[vantseattle]

Good evening all,

I had purchased an 8bitdo a while back and attempted to get it working on my RetroPie before but to little success. Over the last week I have jumped back into the project and my attempts are a little further but now I'm coming across something that is making me sign up and reach out to the experts here. To get the nitty-gritty out of the way I have already updated RetroPie to 4.1.5 and updated the firmware on the 8bitdo. When I use "hcitool scan" from the terminal I am able to see the controller. When using the bluetooth script it will get stuck at the "Scanning..." dialogue and not progress or find any devices. I have left this for many minutes at a time. It would have at least found some bluetooth device in my house.

I started to check the logs and found that I'm getting permission errors when it's trying to launch the service. The log is copied below.

Something else that I will note, when I launched the bluetooth configuration script from the RetroPie-Setup script I received two prompts requesting to overwrite/replace existing scripts. I chose 'yes' at these while the default would have been 'no.'

A few months prior, before the updates, I would have been able to see devices on the bluetooth script.

I'm possibly wondering if those scripts that I overwrote caused this issue.

Thanks in advance for any insight!

@vantseattle did you install the ps3 driver?

[vantseattle]

@BuZz Would the PS3 driver be needed if I'm not using a PS3 controller?

I installed that driver anyways, went back to the RetroPie-Setup script and tried searching for Bluetooth devices again. Still stuck at "Searching..." dialogue with no progress.

@vantseattle The reason I asked, is that installing the ps3 driver disables the bluetooth daemon and gives an error like you were seeing. Uninstall it and see if it helpers (as that resets the permissions again so it should load).

[vantseattle]

@BuZz Ha! Okay that makes a little more sense then. I'll try that now.

[BuZz]

@vantseattle If that doesn't help you can try removing/re-installing the bluetooth stack (making sure ps3 driver is removed first) sudo apt-get remove bluez; sudo apt-get install bluez

@BuZz Thanks for the insight here. So installing then uninstalling the PS3 drivers had fixed the permission issues. I was able to attach the controller and configure the inputs. Thanks!! We can mark this one solved.
