Windows using wrong driver for BT Server

[tartunian]

When connecting to the BT Server example with Windows, the device is classified as a generic BLE device. Are there any drivers known to work on Windows?

On windows Korg-BLE drivers is working fine for me https://www.korg.com/us/support/download/driver/0/530/2886/

On RPI4, I had to compile bluez from source code with --enable-midi option. By default it seems that BT server is just able to deal with audio / network and other device out of midi ones.
In addition, I had to manage the configuration by switching off the authentication & the encryption features.
Then I could achieve to pair and connect my ESP32 device automatically at startup.
