MIDI over Bluetooth

Is is possible with the current software to use Bluetooth MIDI devices? I would like to use a BT MIDI connection the an iPad. I’m not aware about the technical details, but I would guess it is just a serial connection over BT.

As long as the USB dongle is accepted by the underlying Linux, it should work. How about latency in BT?

The RBPi3 has an integrated BT interface, but it’s disabled by default in Zynthian for compatibility problems with the standard serial port:


If you don’t need the standard MIDI serial ports, you could re-enable the integrated BT interface (be aware that if your zynthian case is metallic, you would have a weak signal outside).


So the MIDI implementation just uses the serial port? There is no additional driver needed? I’ll test if I can get this working.

The serial port baud-rate is adjusted for fitting the MIDI specification. It’s a kernel “hack” for the RBPi that you can enable from the “/boot/config.txt”. I never tried to do it in a desktop PC.


@jofemodo, in case if we use usb bluetooth le dongle, the problem will stay the same — it will not live together with MIDI ?

Hi @dhrupadiya!

MIDI over bluetooth is not currently supported by zynthian. We need to do some research, test the raw technology on Zynthian and finally, integrate everything for easy use and configuration.

Documentation about it is scarce because the implementation is quite recent, so we will be surfing the cutting edge, but i would like to see that integrated on zynthian, of course!!

These are the more useful links i’ve found:

And the code itself:

As you can see, we need to learn how to use and integrate this “bluez” thing :wink:

@dhrupadiya, you could start by creating a “feature request” in our issue tracking system:

I’m pretty sure that somebody will catch the task and earn some zynthian reputation points :wink:
