Describe the bug

At first the controller refused to connect. I could pair and trust it when using bluetoothctl, but it always failed when I tried to connect. Now bluetoothctl won't even detect it.

Steps to Reproduce

1. sudo bluetoothctl
2. scan on
3. Nothing happens

Expected behavior

The controller is detected and connects.

Controller and Bluetooth information

I can't get this because my controller won't connect.

Please run bluetoothctl devices to see if it is listed. If it is, remove it with remove GAMEPAD-MAC. Then try again. If it still doesn't work, stop your Bluetooth services, purge /var/lib/bluetooth clean, and reboot. Important: This clears the trust of all your Bluetooth devices, don't purge the directory if you're a using a BT mouse or keyboard with no alternative.

Ok. After purging /var/lib/bluetooth, it detects it now, but fails to pair

Failed to pair: org.bluez.Error.ConnectionAttemptFailed

[kakra]

Did you disable ERTM? Look at /sys/module/bluetooth/parameters/disable_ertm.

[poperigby]

Yeah, I did.

[kakra]

Maybe you could try following the steps from https://github.com/atar-axis/xpadneo/issues/239 to see if it makes you a successful connection?

[poperigby]

I tried all those suggestions and it said Connected: yes, but the light kept blinking. Then it said Connected: no. Then it stopped blinking and said Failed to connect: org.bluez.Error.Failed.

I had the same issue of @PopeRigby , I updated xpadneo to 0.8 and this was the first time too I attemped this via cli, following @kakra made the day

Story time: I got a brand new controller, and it connected flawlessly to my Linux box. I then did some more experiments with it, connecting it to a Windows box, pairing it to another system, ... Now, that controller is no longer pairing automatically and I need to do the "send bluetoothctl connect at the right time" thing to get it to connect, and sometimes it even disconnects again after 30-60s. I'm quite convinced by now that there's something wrong in the controller itself. It worked flawless when fresh out of the box, and now that it's used for a while and has been paired to different systems, it shows the same problem as everyone is seeing. I suspect some internal state or buffer to be messed up. I'm not sure if it's possible to purge the internal memory back to factory fresh state - but if it is, I suspect it would pair and connect instantly again.

Closing old Bluetooth issues, please report to the bluez project if the problem persists.
