Hi there!

Yesterday was the first time flying my Spark after July's FW update. I hadn't had any problems this far apart from the Bluetooth interferences which were solved by simply turning it off on the iPhone.

I went to my usual flying spot and after getting the GPS lock and taking off I noticed the RC and the Spark were communicating via 5.8Ghz instead of 2.4 as before. Everything seemed fine until after a couple of minutes and when the Spark was 100m away from me I suddenly lost connection to the aircraft and it automatically initiated a RTH manouver.

On its way back to me I regained connection and lost it several times. At no point did I get a low signal or interference warning. Luckily I managed to get it back with no issue but now I'm concerned to fly it, to be honest.

Here's the flight log: http://healthydrones.com/main?fl ... ENERALNotifications

I tried to report the .DAT file from DJI Assistant 2 but it would complain about the phone number format when submitting the form and wouldn't let me.

Any suggestions would me much appreciated!

Thank you very much, I have forwarded the data files to engineers for further analysis, will get back to you  when we get the result.
Appreciate your support!
