One note at a time, not a full Midi player. Android connects to the MD-BT01 just fine. Appshows a smalll keyboard with which u can plink out a note at a timeand you can watch Midi I/O events via BLE as the DKV plays or keys played.
Somebody needs to write a full BLE Android Midi player app, or adapt an existing one by utilizing the new BLE APIs - similar problem to Windows 10. IMO, not enough demand for mainstream app developers to consider it worthwhile unless a company like Yamaha bankrolled it.
