[Sr Huang]

www.microsoft.com/.../universal-foldable-keyboard Why microsoft BT keyboard have 3 mode to support IOS, Android, Windows? But we only have 1 sample for HID_keyboard. Can Nordics provide specific samples for IOS, Android, Windows?

@Sr Huang: We don't know what exactly Microsoft does with the button. But I guess it's could be some optimization for each OS as well as the function keys customization. It's described in the keyboard's spec: download.microsoft.com/.../TDS_UniversalFoldableKeyboard.pdf

Thanks. I really hope Nordics can detail study Windows7 as well.

@Sr Huang: What do you mean ? Windows 7 doesn't support BLE natively.
