Obviously your device doesn't seem to have the PROEDITION firmware with AttitudeControl feature installed. You can check this by connecting your AR7210BX to the computer or smartphone using the USB2SYS/BLE2SYS interface. In the StudioXm app you can see on the device overview page which features are installed on the device. Use StudioXm to upgrade the firmware to PROEDITION.
