Cannot connect patchbox to iPad Pro Bluetooth

[Giedrius]

Recompiling BlueZ is no longer necessary - the packaged version in Raspberry Pi’s APT has MIDI support enabled. So RPi can connect to BT MIDI peripherals out of the box, but the RPi has to be configured as one for other devices like iPads to see it as a BT MIDI device. It’s a bit of a mess, this could have been designed way better. Also, there’s no standard and ready to go BT MIDI service to enable such functionality on Linux yet, but it can be set up, see my short guide here:

Patchbox as BLE MIDI Device?

By default there’s no service running ready to accept incoming BLE MIDI connections. However, looks like if you’d connect the Pi to some BLE MIDI device, an ALSA MIDI port would appear for it. I’ve looked into this, and looks like there’s a btmidi-server program available to accept connections from phone devices. Unfortunately it’s not conveniently available just yet, but can be installed by running these commands: (I probably had many of the libraries this depends on already installed, if you…
