Xbox One controller via Bluetooth

This thread has 67 THOUSAND views! This seems to be a popular controller, is it just not being used by the people who matter?

Hi peeps, first post on here after getting my Pi yesterday.

So, Xbox One S controllers eh, who knew they would be so much trouble? I've been tearing my hair out since yesterday, but found a solution to my issue, so hopefully someone else will find this post helpful!

It's been well documented that in order to pair or connect a modern Xbox One S controller (bluetooth) you have to disable the ertm option, and I'd had success when running this from the command line after boot up...

sudo bash -c 'echo 1 > /sys/module/bluetooth/parameters/disable_ertm'
cat /sys/module/bluetooth/parameters/disable_ertm
(the second command will return 'Y' when ertm is disabled, and 'N' when still enabled)

However I could not get it to persist using the suggested method i.e. adding it to /opt/retropie/configs/all/autostart.sh directly before the 'emulationstation #auto' line, so I would have to log in with puTTY and run the command manually every single time I wanted to use the Xbox controller! (super annoying).

So, happily I finally found another way to disable ertm for bluetooth.

1. Create a new file using nano...
   sudo nano /etc/modprobe.d/bluetooth.conf

2. Add a single line to the new file...
   options bluetooth disable_ertm=Y

3. Exit nano, saving the file in the process.

For reference, I'm using the latest release of Raspbian Stretch and RetroPie at time of going to press (December 2018), on a Pi 3 Model B+.
