The beeping is from the sensors warning you that there are obstacles.

That is indeed the sensor telling you that there are obstacles. Your front and back sensors are on.

Sounds like typical sensor warnings.  I get the same warnings until I get the drone up and away from sensed obstacles, then all quiet.  

I also have this issue… I fly with the sensors off 90% of the time, but it still beeps at my as soon as I take off, until I get out away from obstacles? Is there any way to completely turn off the beeping? It’s incredibly annoying! I don’t exactly want to mute my phone because I’d still like to hear other info or warnings, but I don’t want to hear that beeping every time I take off or land…

Thank you for keeping us posted. With regards to this safety feature. It is not advisable to disable the notification for the sensor for safety reasons, the beeping sound comes from the mobile device. You can try to lower the volume of your mobile device. But you need to always pay attention to the messages that pop up on the app and keep it safe. Thank you.
