Getting Bluetooth to work on Raspi 3?

Postby aabasobo » Mon Aug 14, 2017 9:29 am

Hi all,
1 have a raspberry 3 with bluez and bluez-utils installed. After starting bluetooth.service, bluetoothctl says, on power on command, "no default controller available".


Here is output of lsmod, seems that hci_uart module is not loaded at boot.

$this->bbcode_second_pass_code('', '
]$ lsmod

')

Bluetooth service runs ok, but I cannot scan with bluetoothctl.

I actually have another arch raspi 3 that has a working bluetooth, but I cannot remenber how i got it working :evil:

Testing things....

I plugged in a usb bluetooth adapter, and voila, bluetooth works without touching anything. No need for modprobe btusb.

I still don't know why raspi 3 onboard bt does not get started same way. Wlan works just fine, though...

Here is output of lsmod with usb bt module:
