Hi,
I'm trying to get bluetooth up and running on a headless RK3399 running Ubuntu. The kernel certainly seems to see it:
mitchekl@firefly:/usr/bin$ dmesg | egrep -i 'blue|firm' [ 0.000000] psci: PSCIv1.0 detected in firmware. [ 0.211503] Bluetooth: Core ver 2.21 [ 0.211590] Bluetooth: HCI device and connection manager initialized [ 0.211626] Bluetooth: HCI socket layer initialized [ 0.211657] Bluetooth: L2CAP socket layer initialized [ 0.211707] Bluetooth: SCO socket layer initialized [ 1.781735] Bluetooth: HCI UART driver ver 2.3 [ 1.785455] Bluetooth: HCI UART protocol H4 registered [ 1.807823] Bluetooth: HCI UART protocol LL registered [ 2.140563] Bluetooth: RFCOMM TTY layer initialized [ 2.143705] Bluetooth: RFCOMM socket layer initialized [ 2.146821] Bluetooth: RFCOMM ver 1.11 [ 2.149865] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 2.152954] Bluetooth: BNEP filters: protocol multicast [ 2.155976] Bluetooth: BNEP socket layer initialized [ 2.159068] Bluetooth: HIDP (Human Interface Emulation) ver 1.2 [ 2.164293] Bluetooth: HIDP socket layer initialized [ 2.215665] of_get_named_gpiod_flags: parsed 'uart_rts_gpios' property of node '/wireless-bluetooth[0]' - status (0) [ 2.215672] [BT_RFKILL]: bluetooth_platdata_parse_dt: get property: uart_rts_gpios = 83.

However, whenever I look for an hci device I find nothing. I've tried the following, all to no avail:
mitchekl@firefly:/usr/bin$ rfkill list all 0: bt_default: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: yes Hard blocked: no 2: brcmfmac-wifi: Wireless LAN Soft blocked: yes Hard blocked: no mitchekl@firefly:/usr/bin$ sudo rfkill unblock bluetooth mitchekl@firefly:/usr/bin$ systemctl status bluetooth ● bluetooth.service - Bluetooth service Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled) Active: active (running) since Thu 2017-04-20 15:38:03 PDT; 3min 46s ago Docs: man:bluetoothd(8) Main PID: 23993 (bluetoothd) Status: "Running" CGroup: /system.slice/bluetooth.service └─23993 /usr/lib/bluetooth/bluetoothd

Any idea what I'm doing wrong, or if there is a more fundamental issue?
Thanks!
