Hi all first post here. Been flying the P4 for a few weeks now and all apears to be going ok. However, today on my second flight I used the auto take off and immediately lots of bleeps began but no message on the iPad mini 3 and as soon as I pushed the left stick she acended just as before and all the beeps stopped. Just wondered if anyone had experienced something similar and if this will be recoded in the system log. Not sure how to get into the log so any help here would be great. Thanks.

coulda been your obstacle avoidance picking something up, mine does it once in a while if its pointed @ me when I take off

Make sure there isn't any obstacle in front of the drone and clean the OAS.
