When using [SYS] for the F.Port signal, you must connect the BLE2SYS / USB2SYS adapter at the DI2 port in order to use the StudioX app. Here you need the optional adapter from standard servo connector to 5-pin JST. Alternatively you can simply disconnect the F.PORT signal from SYS temporarily, switch off your radio and power cycle your device. It will then enable "normal" SYS operation for programming purpose. Please note that in this case you will not be able to control the system from the radio during setup with StudioX.
