multiple usb bluetooth dongles

[ikookal]

Hi Everybody,

I'm trying to create a system where, eventually, I can play 4 wav files (or mp3) simulatiously on 4 different bluetooth headphones.
For starters I'm trying to get this to work on two devices but I seem incapable to do so.
Since I dont believe it's possible to achieve this from one bluetooth dongle I am using a dongle per audio "track".
Right now I am able to pair with the two different bluetooth headsets independently from each other. I can play wav files one after the other on both devices and I can do this from two different bluetooth usb dongles. the only link missing is "simultaniously".

using lsusb I am able to see both my dongels.

Code: Select all

Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 004: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 001 Device 005: ID 0b05:17cb ASUSTek Computer, Inc.
Bus 001 Device 007: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

this is what my /etc/asound.con looks like:

Code: Select all

pcm.bluetooth {
    type bluetooth
    device FC:58:FA:7E:EE:3F
    profile auto
}

ctl.bluetooth {
    type bluetooth
}

pcm.bluetwo {
    type bluetooth
    device DF:57:34:00:2D:B8
    profile auto
}

ctl.bluetwo {
    type bluetooth
}

besides that it might be handy to mention that I compiled the latest version of bluez (5.37).
It also might be worth mentioning that I have been able to play 3 audio files at the same time on two usb soundcards and the on board analog audio jack.

does anybody know if this is possible with bluetooth to begin with and if so how i could achieve this.

thanks in advance,
