Have not used in a while . Went to update to current version today. The ST16 updated fine but the drone will not because of the older version. can anyone link me to older firmware versions? Thanks in advance!
Your system will update without requiring an intermediate update version. The notice is just telling you what version of firmware has to be installed in the aircraft and camera in order to take advantage of what's now in the -16.
In all probability what you are experiencing is a condition where the -16 is no longer recognizing the aircraft auto pilot. Put the -16 into team mode and go search the system again to "see" and bind it.
