Howdy! I've just purchased a KCC and am unable to get it to connect to my Fettec AIO. Upon loading of the FC, the KKC says I need to update and displays a QR code. I've updated the KKC to latest FW 1.35 but it still will not connect to my Fettec AIO running FETTEC_FC_G4-1.3RC47m. Is there a different KKC firmware I should use? Thank you.
