    I have a Raspi3 with HifiBerry running on max2play 2.52.
    I activated my license and installed bluetooth support. I was able to connect my cellphone (OnePlus 7 Pro, Android 10) once but I never was able to hear any music. When I disconnect and connect again, the connection is established but immediately dropped. Can you help me?

    Here is the Bluetooth DEBUG output:

    Hi Clarenze,

    Thank you for the debug info. In order to narrow down the problem, please answer the following questions: Have you enabled direct streaming to the sound card or installed streaming to the Squeezebox Server? Do you use a bluetooth dongle or the integrated bluetooth? Do you use our stretch image or buster?

    17. Oktober 2020 at 10:10 #49854


    It is configured to „direct streaming to the soundcard“.
    I intend to use the integrated bluetooth adapter.
    The Debian version is 9.4. It is the image provided by you (I bought a pre-installed max2play package).

    Hi Clarenze,

    Please make sure you have followed the steps for direct Bluetooth streaming on our wiki:

    If the problem persists, please try to download a new stretch image from our download page and burn it to the SD card. Then try the Bluetooth connection again.

    I tried that now, but it still does not work. I think the bluetooth feature never worked. I tried on a different device one year ago and had exactly the same problems. Also back then support was not willing to do anyhting beyond recommending to reinstall. This is a big disappointment. Every 50€ bluetooth speaker can do this.

    Hi Clarenze,

    I tested bluetooth streaming again and could not reproduce the problem. So I am assuming that there is a configuration error. Can you connect your mobile phone to the Pi via the plugin? Can the Pi find any Bluetooth devices in the area?

    It sometimes works when I click connect within the max2play frontend. Connecting from the phone never works. It connects and immediately disconnects again.
    Does a USB bluetooth dongle work better than the built-in one?

    Hi Clarenze,

    A Bluetooth dongle can help, but the Pi’s integrated Bluetooth should also work as long as nothing interferes with the signal. Did you install the Pi in a case and did you connect the Pi to the internet via WiFi? In this case the Bluetooth signal may be disturbed.

    I started yet another attempt to get bluetooth streaming working on the max2play/rapsi3 device.
    I installed a bluetooth dongle now, as you suggested (1mii Bluetooth Adapter PC), but max2play still uses the built-in adapter.
    I tried activating the USB device by hand, but I get an error message:

    How can I activate hci0?

    Hi Clarenze,

    You can deactivate the built-in Wifi in the Raspberry settings. Your wifi dongle may still need a suitable driver. You can install it with the following commands, provided your dongle is connected and recognised by the system:

    sudo wget -O /usr/bin/install-wifi
    sudo chmod +x /usr/bin/install-wifi
    sudo install-wifi

    Restart your system afterwards.

    My question was regarding bluetooth, not wifi.

    4. November 2021 at 14:26 #51775

    I am very sorry. I do not know what I have read there.

    Nevertheless, the internal Bluetooth can be disabled via the Raspberry settings. Apart from that the BT dongle should be detected automatically. The error with hci up could be caused by an outdated kernel. Maybe a kernel update (also available via the Raspberry settings) will help.
