Please post some details about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

@zerojay I didn't try disabling Wifi (I don't have wifi disabled now and its good) I tried every mode, for hours and they just weren't working.

Apparently this is an issue with the SN30 Pro itself. I got it working. Here's what I did: Deleted /etc/udev/rules.d/99-bluetooth.rules Deleted SN30 Pro from registered Bluetooth devices Powered on SN30 Pro with Start+B (Android mode) and held Pair button (top of controller) for 3 secs to immediately go into pairing mode. While in pairing mode selected Register and Connect Bluetooth Devices in RetroPie-Setup Script >> Setup >> Configure Bluetooth Devices Selected 8Bitdo SN 30 Pro from list and finished config Did NOT set up udev rule Now the controller is working perfectly; I'm able to open Launch Menu or go straight into games ... no sitting at black screen for ~40 secs. Also no waiting required to navigate script menus either. I did have to reconfigure controller layout ... and the L/R triggers are actually recognized now as well.

@mitu said in Problems connecting bluetooth controllers: Glad you found the solution, this issue will probably be fixed with the next Raspbian package update for the pi-bluetooth package. Package has been updated, with the fix referenced in the Raspbian forums.

Drivers are usually not installed in the image, you have to install them - such is the xpadneo driver.

ok so that may not have been my problem but i did get it paired but the only change i did was for something else which was turning off hardware acceleration cause it would crash when trying to scroll through games. dont have any idea how there connected though. but after that paired just fine.

Awesome! This worked like a charm. Thank you!

@mitu Awesome, thanks!

Can you provide some more details here for the SN30 and how you paired it. I think I am getting lost. I currently have it in switch mode, and all buttons except a few are working right now. I will try pairing it another way to see where I get.

4.2 is very old release, you should update to a more recent RetroPie version, as we cannot continue supporting such old version.

@quicksilver I did not know that. Sorry, but I can't change that now.

@gordonfreemanjr do you have any other controllers plugged in? Did you map your keyboard as a controller? It may be worth going into RetroPie-setup and resetting your mappings and then remapping just to see if that fixes the light issue.

@mitu OK thanks

where do i put this pairing code?

thanks again Mitu, didn't even know there was one, will try again. Thanks for helping with my issues.
