Couple of days ago I received Typhoon H PRO version (with RealSense) EU version. Yestarday I only started ST16 and typhoon H to see how things are working and everything seems to be fine, telemetry is received , camera working ok. I haven't done GPS calibration, Accelerometer and gimbal yet. Today I downloaded firmware for the ST16 , this new firmware available for download and succesfully uploaded to the ST16. But after this upgrade ST16 not wanted to connect to the camera or aircraft. Ok so i switched off both and again ON. Now after while camera finally showed picture on the screen but there is no telemetry data from the aircraft. Nevertheless ST16 is showing Typhoon H version firmware. But when I go to Bind screen it is showing that aircraft is not connected. So I figure that maybe I need to do Typhoon H firmware upgrade so I did and it went successfuly too, ST16 showing new firmware on the aircraft but again, there is no connection to the aircraft at all, only camera showing video feed but is not controlable. Any advice what am I doing wrong after upgrades ?
