    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?

    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.
