Downgraded Ac and RC to previous firmware which is .400 2. Powered on Ac then RC and connected phone with mobile data turned on in the iPhone 3. Drone connected to home point and locked 11 sats (which gps signal bar turned white) in under 2 minutes 4. Turned drone off and removed battery for 2 hours ( watched movies) 5. Turned on drone again then RC and connected iPhone but I turned off the phone mobiles data - Put it into Flight mode- drone connected to 11 sats-turned white and recorded home point in under 2 minutes again 6. upgraded RC to .500 and left drone on .400 firmware- Full sat lock took 3 minutes this time to record the home point. Locked 11 sats again which turned GPS bar to white 7. upgraded drone to .500 (latest firmware) and downgraded RC to previous firmware .400 and drone locked full 11 sats in 53 seconds after being turned off for 2 hours - cold start 8. upgrade both drone and RC to latest firmware .500 and turned on drone then RC with Mobile data on phone enabled and drone took 6 minutes and 36 seconds to locks 12 sats and record home point. 9. Downgraded RC again, left drone on latest firmware and tried after an hour and the drone locked full sats in 1 minute and 30 seconds. How is this possible that the RC when on the latest firmware causes the drone to take longer to register sats. When the drone and RC is on the previous firmware which is .400 the drone only needs 11 sats to register the home point but on the latest firmware needs 12 sats to register. The story about mobile data and using the phones A-GPS has been debunked here but something is not right in the firmware for the RC which should have nothing to do with locking in satellites. One thing I can be 100% sure of is that when I downgraded both the drone and RC to the previous versions I also managed to get alerts again from AirSense. This proves beyond a shadow o doubt that the newest firmware, although gave us all the missing features caused major issues for some, if not the majority of us with GPS and AirSense. I hereby urge Dji to hurry up and produce an update that will gives AirSense back and working GPS times with all the features that we paid for.
