Bug Description
Hello,
I have recompiled Bluez from source following https:/
I have a Korg nanoKONTROL Studio MIDI controller which connects either USB (works fine) or Bluetooth.
Before recompiling, bluetooth would connect the controller in a stable manner but no MIDI signal would be available, which is why I recompiled.
After recompiling with MIDI enabled, it connects and then disconnects after a few seconds. I must be a step further, but what's next ?
Below information as requested on https:/
