Android BLE pairing with windows 10

Question

I am facing the folowing problems when trying to pair my Androids BluetoothGattServer and BluetoothLeAdvertiser with Windows 10. My BluetothGattCharacteristics are protected with PERMISSION_READ_ENCRYPTED_MITM / PERMISSION_WRITE_ENCRYPTED_MITM.

1) When pairing windows, the I have to insert a constant pin "000000". That seams very unsecure compared to the passkey variant that is used pairing the same device with Bluetooth Classic.

2) Android 5 introduced rotating MAC addresses. Windows fails to reconnect to the paired device somehow.

Any ideas? Thanks in advance.

EDIT

Bluetooth Manager is showing "Driver Error" and the Device Manager reports "Windows has stopped this device because it has reported problems. (Code 43)" on this device.

Answer 1

Just reported this Problem to Microsoft and Android.
