Max2play Bluetooth – Use Echo and fire TV as sources

Just an update to echo problem. As someone on the the forum mentioned, i did the below steps:

1. Connect Echo. Sound Still comes from echo and not from connected M2P device.
2. I asked Alexa to disconnect Bluetooth and Connect Bluetooth.
3. Magically, when i ask anything to Alexa now, sound comes from M2P device !

Its just annoying to disconnect and connect alexa everytime to ensure alexa can act as a source to m2P device ! Any fix for this ?

Also I am still unable to connect Fire TV Stick to M2P device via Bluetooth.

Also, to add, If i am able to connect Fire Tv Stick, can M2P automatically switch the between echo and Fire TV based on whats playing ?

Finally I got it working !!! I was able to connect my Fire TV Stick to M2P Bluetooth Receiver.
I followed the original instructions from
https://www.max2play.com/en/forums/topic/using-pi-as-bluetooth-speaker-make-pairing-easier/ but unable to setup successfully.

As mentioned in above post, I did set the class to 0x00041C as below:

sudo hciconfig hci0 class 0x00041C

However whenever i try to make the bluetooth adapter in M2P discoverable it gets reverted back to 0x0c0000

So, I added the below line to /etc/bluetooth/main.conf in Default device class section.
Class = 0x200414

so it looks like:
# Default device class. Only the major and minor device class bits are
# considered. Defaults to ‚0x000000‘.
#Class = 0x000100
Class = 0x200414

and then run
sudo systemctl status bluetooth.service

I used 0x200414 as my device class and it worked perfectly. I included more classes below that you can test ! i generated them using
http://bluetooth-pentest.narod.ru/software/bluetooth_class_of_device-service_generator.html

================================ Device Classes ====================================
Major Service Class | Major Device Class | Minor Device Class | Bluetooth Code
——————– ——————– ———————– —————-
Audio Audio,Video Loudspeaker 0x200414
Audio, Video Portable Audio 0x41C
Audio Audio,Video Portable Audio 0x20041C
Audio Audio,Video HiFi Audio Device 0x200428

======================================================================================

Also i ssh’ed into M2P device, and then

sudo hciconfig -a (check whether its showing the new class)
sudo bluetoothctl (to go into bluetooth prompt)
discoverable on
pairable on
agent on
default-agent on

Now Start Fire TV, and scan for bluetooth devices, Your M2P should definitely show up, Pair it and also ensure you fill in the prompts you get on bluetoothctl prompt on your M2P device. Thats it Enjoy
the Fire Tv sound on M2P connected Speaker !!

If you connected Bluetooth Speakers, make sure to set the soundcard of your audioplayers to bluetooth as audio output! You need to restart your Audioplayer if the Bluetooth Device changed.
If you connected a Smartphone to stream to Squeezebox Server, NO further setting to your soundcard is needed (do NOT set your soundcard to bluealsa)!
