I use a DJI Osmo and I have a rode filmmaker microphone attached.  The microphone works well some of the time.  But when my phone starts searching for networks (I presume this is what causes it as it does similar in the car) I get beeping noises on my recorded sound.  How do you get around this?  If the phone was in airplane mode it would work fine but obviously I need the wifi for connection to the osmo.  (I use an iphone 6s)

Any help hugely appreciated.

Thanks

Hi Kirk, it's the WiFi microphone, and easy to be affected by the interference, please try to connect another WiFi  frequency band.
