## BT Dongles
Please report your Dongles and how they work [here](https://github.com/atar-axis/xpadneo/issues/93)
## Bluetooth Low Energy
Some newer controller may work in Bluetooth low energy mode (BLE). One of
those controllers is the XBOX Series X|S controller.
If your distribution supports the command, run `btmgmt info` and look for
`le` in supported and current settings, example:
```
# btmgmt info
Index list with 1 item
hci0: Primary controller
addr 00:1A:7D:XX:XX:XX version 6 manufacturer 10 class 0x100104
supported settings: powered connectable fast-connectable discoverable bondable link-security ssp br/edr hs le advertising secure-conn debug-keys privacy static-addr phy-configuration
current settings: powered ssp br/edr le secure-conn
name jupiter
short name
```
If `btmgmt` command is not available, try `bluetoothctl mgmt.info` instead.
