I told about this issue : https://quality.embarcadero.com/browse/RSP-15489
I try it in Berlin 10.1 on Win 10 but MobileDevices.xml not exist in any place !
at 9 min you provide wrong information. You still not supported BLE in Win10 because can`t discover not paired devices. This issue still not resolved
How long you will ignore that BLE still not worked in Win10. Many users want to create Apps for Microsoft Store but you can`t discover not paired devices! Exist new API that give it but you work about Linux servers !
