In iOS 7, Apple supports system wide HID over GATT so a BLE peripheral can act as an input device and send key events to system. For camera app, it will take volume button action to capture picture so letting your BLE peripheral send volume event should technically give you the same result - capture picture. you can check here for profile define: https://developer.bluetooth.org/gatt/profiles/Pages/ProfileViewer.aspx?u=org...

Hello, I seen some messages regarding this topic but I did not fully understand what is really possible to do with a PURE BLE solution (without MFI program)

Use case: Using a BLE (CC2540 tag) to take a picture using the native iOS app Questions: - Is it possible ? - Mode to be used by the BLE firmware (peripheral or manager) ? - Profile to be used on the iPhone / iOS stack ? - How to control the native iOS Camera app ?
