I am developing a BLE peripheral with GATT servers on the windows platform, but I found there is no windows API to set custom data to Scan Response(or Scannable, I am not quite sure about the difference between Scannable and Scan Response). Can you please provide the API to implement this, It would be helpful to provide some code examples, thanks

Universal Windows Platform (UWP)

    Hello,
    Welcome to Microsoft Q&A!

    but I found there is no windows API to set custom data to Scan Response

    Scan response data are not directly controllable from the App. I have to say it has no such method for writing scan response data directly, you need refer ADVERTISING AND SCAN RESPONSE DATA FORMAT to make scan response data manually. If the App wants more space, they can consider enabled extended advertisement (only available on systems that have radios that support this on both sending and receiving sides). They can use BluetoothLEAdvertisementPublisher.UseExtendedAdvertisement Property (Windows.Devices.Bluetooth.Advertisement) - Windows UWP applications | Microsoft Learn

    Thank you.
