BT issues

protheval

Dear all, so far I’m having a blast with my Batocera PC, thanks a lot to all contributors for the amazing work.

I have an issue though: tried several BT USB adapters including the one from 8BitDo and a Broadcom BCM20702A0 which seems pretty common and I can’t use bluetooth whatever I try.

lsusb output: Bus 001 Device 002: ID 0b05:17cb ASUSTek Computer, Inc. Broadcom BCM20702A0 Bluetooth

When I try to launch bluetoothctl I have had this output with my three different dongles: Waiting to connect to bluetoothd…

What am I doing wrong?

thank you for your help

Which controller do you want to connect via bluetooth?
What happens, when you put your controller into pairing mode and then go to Controller Settings, “Pair A Bluetooth Controller”?

I have a bunch of BT controlers, PS4, 8BitDo… Anyway when I click on the ES menu to pair a BT controler, nothing happens at all. It almost looks like as if the service was not launched during boot, don’t know why.

Happened on the latest stable version, issue still here with beta (OS version: 5.27.2 2020/09/22 23:35). On Ubuntu I would know where to look, but I must admit I’m a total noob with Batocera.

Found that error in dmesg output: [ 3.057205] bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0b05-17cb.hcd failed with error -2

Edit: also found Bluetooth: hci0: BCM: Patch brcm/BCM20702A1-0b05-17cb.hcd not found

Clicking on the ES menu to pair a BT controller is the second step.
The first step is to put your controller into pairing-mode (for PS4-controllers you have to press and hold the ps- and the share-button together for about 5 seconds, until the LED is flashing. for 8bitdo controllers it depends on which 8bitdo controller exactly you are using. for the most 8bitdo controllers you have to press and hold start+b or y or x (depending on which mode you want to use) to start the controller and then press and hold the pair-button for 2-3 seconds, until the LEDs are blinking).
Did you do that before?

yes I did, same, nothing happens, clicking on the menu does not trigger any action. I am not sure but the output of the batocera-bluetooth-agent command seems a bit odd to me, as if no bluetooth service was running:
Traceback (most recent call last): File "/usr/bin/batocera-bluetooth-agent", line 318, in <module> adapter = bluezutils.find_adapter(None) File "/usr/lib/python2.7/bluezutils.py", line 14, in find_adapter return find_adapter_in_objects(get_managed_objects(), pattern) File "/usr/lib/python2.7/bluezutils.py", line 9, in get_managed_objects manager = dbus.Interface(bus.get_object("org.bluez", "/"), File "/usr/lib/python2.7/site-packages/dbus/bus.py", line 243, in get_object follow_name_owner_changes=follow_name_owner_changes) File "/usr/lib/python2.7/site-packages/dbus/proxies.py", line 250, in __init__ self._named_service = conn.activate_name_owner(bus_name) File "/usr/lib/python2.7/site-packages/dbus/bus.py", line 182, in activate_name_owner self.start_service_by_name(bus_name) File "/usr/lib/python2.7/site-packages/dbus/bus.py", line 280, in start_service_by_name 'su', (bus_name, flags))) File "/usr/lib/python2.7/site-packages/dbus/connection.py", line 653, in call_blocking message, timeout) dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name org.bluez was not provided by any .service files

then i guess, that your bluetooth dongle is not recognized/supported.
try with another one.

for me those usb bluetooth dongles do work:

Asus BT21 / Trust USB BT dongle
Hardware-ID: USB\VID_0A5C&PID_2148
Broadcom 2046 Bluetooth 2.1+EDR USB Device

Logilink BT0007 / inateck USB Bluetooth 4.0
Hardware-ID: USB\VID_0A12&PID_0001
CSR8510A10 (Cambridge Silicon Radio) Bluetooth Chip

Ok, tried with a Ugreen adapter, reported to work, and it doesn’t work either. Tried 4 different usb BT adapters known to work on Linux (and, for some users, on Batocera) with no success, so I’m giving up.

@joinski , thanks a lot for trying your best to help, much appreciated. Will update if I ever find a solution.

that’s strange.
you are the first one, in several years, i heard of, which has such problems with bluetooth.

maybe you can come to the discord channel and report your issue there to one of the devs? they can surely help you
