Bluetooth controller input not recognized

Norde · December 18, 2019 at 8:57 AM

Hello all Libreelec user and Libreelec team !

First of all thank you for all the work accomplished

I encounter some problem with my Xbox One controller paired in bluetooth : input are not recognized under LibreElec.

The controller is well paired and input are detected under btmon but not with Kodi (under Input devices menu when trying to map controller)., except the "Home" button.

There's no error in log and using the xpadneo driver instead of xpad doesnt help.

I cant figure out where the problem is comingfrom (my knowledge is not sufficient).

This seems to be only related to LibreElec since when installing Kodi on raspbian or using it with other distributions (recalbox), there's no such problem.

Any clue ?

My hardware and software setup :

> Raspberrypi 3B+

> Xbox One controller (v1708) connected via onboard bluetooth

> Libreelec 9.2 (fresh install, no addons and all settings set to default)

> ERTM bluetooth mode is disabled to allow pairing of the Xbox One controller (/sys/module/bluetooth/parameters/disable_ertm set to 1)

Hmmm - I've used a Logitech F710 (Similar to Xbox controller) without issues on earlier releases.

Please provide a full debug log.

How to post a log (wiki)

1. Enable debugging in Settings>System Settings>Logging
2. Restart Kodi
3. Replicate the problem
4. Generate a log URL (do not post/upload logs to the forum)

use "Settings > LibreELEC > System > Paste system logs" or run "pastekodi" over SSH, then post the URL link

Indeed, strange that a similar bluetooth controller works and not this xbox one pad ...

On a fresh install (after adding "options bluetooth disable_ertm=1'" in /storage/.config/modprobe.d/bluetooth-disable-ertm.conf) Xbox one controller was paired and connected in bluetooth.
For the tests I went to the gamepad settings menu for and tried to assign the A , Up then Guide keys to the bluethoot gamedpad.

I might have the same problem, I can no longer get any input to Kodi from my 8BitDo SN30 bluetooth controller.

It's connected and the input shows up with btmon.

And I think this used to work with a 9.2 alpha, but not with the current 9.2 + kodi 18.5.

Maybe some of the input/controller plugins are involved also...

Is there something we can do to help finding the bug/regression ?

I can't really test on nightly right now, but that would probably help narrow down the issue:

There was some modifications related to bluetooth devices in nightly?

No idea, just an idea to narrow it down.

Hi,

did you solve the problem? I had a similar problem with a Xiaomi BT Gamepad and the problem are these lines in the log:

As you can see the gamepad is registered as mouse and as keyboard (for me it was joystick and keyboard) and thus a mouse event and a keyboard event are emitted at the same time. libinput apparently can't handle this and thinks the button bounced and tries to debounce, which does not work. In my case I wrote a udev rule to disable the libinput registration of the keyboard:

Code

ACTION=="add", SUBSYSTEM=="input", KERNEL=="event[0-9]*", ENV{DEVPATH}=="*2717:3144*",  ENV{LIBINPUT_IGNORE_DEVICE}="1"

After that only the joystick was regognized and it works just fine. See Xiaomi bluetooth gamepad not working for further information.
