I’m using Fedora 38, which doesn’t compile Bluez with MIDI Bluetooth enabled (which would be appreciated btw), so I compiled it myself installing the dependencies, downloading the source code from www.bluez.org, I configured it like this
sudo ./configure \
--enable-midi \
--enable-sixaxis \
--enable-cups \
--enable-nfc \
--enable-mesh \
--enable-hid2hci \
--enable-testing \
--with-systemdsystemunitdir=/etc/systemd/system
then I did sudo make
sudo make install
and rebooted.
After that when I connected my MIDI keyboard over Bluetooth it started showing up on aseqdump -l
but when I do aseqdump -p <port_of_midi_keyboard>
there doesn’t seem to be any communication going on.
