Today the first flight after the firmware update. Just switch-on the H, the audible alarm started to sound continuously (but with intermittent beep). Switch-Off and on, no abnormal sound signal. The CGO3 + gives Initialization error, but the video streams are normal, both towards ST16 that towards the microSD. The disappointment is that after every take-off, the wi-fi has lost the connection (always a few tens of meters), catching it after about 1 min. The interruption of the wi-fi did not interrupt the recording, but, of course, prevented to rule the video. After the firmware update, I have not made any calibration (in GUI seemed all right), but, I think, the wi-fi problems should be independent from the calibration. I using the European version of fw; by the various threads, I understand that in the European version, the wi-fi, there have been not great improvements. To you, the wi-fi connection, how it works ? Thanks for any response.
