    Hi,

    I’m using my PI as airplay and bluetooth streaming endpoint and both work fine. I’ve setup BT in the bluetooth page and I’m using the Bluetooth-Speaker plugin.

    I really like Max2Play and I appreciate all the work that went into it.

    Issue:
    I found it very difficult to pair devices with my pi. The discover-device button sort of reverses the proccess that I expect as end-user. I wasn’t able to pair my firetv at all with the gui.

    How I think it would be great:
    Userstory:
    Goal: I want to to play music from my phone on my pi with bluetooth
    Process:
    – I put the PI into pairing mode by clicking a button on the bluetooth page (alternative PI is always in pairing mode)
    – I scan for BT-devices on my phone and I expect the max2play to show up
    – I connect to the max2play BT and I’m ably to pair with a passcode (or no password at all)

    Workaround:
    Here is how I was able to pair my firetv on the cli:

    – Configure bluetooth device as AUDIO player: sudo hciconfig hci0 class 0x00041C
    – Run bluetoothctl:
    Make the device discoverable and pairable and perform the pairing:

    [bluetooth]# discoverable on
    Changing discoverable on succeeded
    [bluetooth]# pairable on
    Changing pairable on succeeded
    [bluetooth]# agent on
    Agent registered
    [bluetooth]# default-agent
    Default agent request successful
    [CHG] Device XX:XX:XX:XX:XX:XX Connected: yes

    [CHG] Device XX:XX:XX:XX:XX:XX Trusted: yes
    Changing trust succeeded

    Questions:
    – Are there any plans on making the pairing process more user friendly?
    – Shouldn’t the interface be always configured with a device class as audio player?
    – If I set the class and make my bluetooth adapter permanently discoverable in /etc/bluetooth/main.conf will that get overriden by max2play?

    Hi Sebastian,

    Thank you for the detailed feedback!

    Hi Heiner,

    any news regarding this topic?
    I’m also searching for a easier pairing solution …
    It would be very nice to do the pairing from the device you want to pair (e.g. smartphone) without any action required on the M2P device.
    Or at least as Sebastian wrote, after setting M2P into pairing move by a button on the webinterface (or a hardware-button connected to the GPIO).

    Kind regards
    Georg

    Hello Sebastian,

    Thank you for this tip ! I was trying to do the same thing to pair my Fire TV stick with M2P speaker but not not successful yet !

    After making the M2P discoverable and pairable, I turned the agent on and also did default-agent.

    At this time, I start searching for M2P device in Fire TV Bluetooth settings but it doesn’t seem to find it / discover it at all !

    So I am not getting the below

    [CHG] Device XX:XX:XX:XX:XX:XX Connected: yes

    Do you have any suggestion for me to pair my Fire TV to M2P. I bought a new soundbar and would really love to connect it with M2P. It is connected to M2P (Pi 3 with HiFiBerry Digi+ connected to optical input of my soundbar).

    This is the fire stick I am using: Fire TV Stick 4K with Alexa Voice Remote
