Dear Client Thank you for contacting DJI.

We recommand you use real phone instead of virtual simulator.

Hopefully our solution can help you. Kindly Regards, DJI Developer Support

Dear Client Thank you for contacting DJI.

I think some of the low level hardware related functions influence so the simulator cannot provide it.

Hopefully our solution can help you. Kindly Regards, DJI Developer Support

Hello @dji-dev !

I have encountered quite a few of these posts all over the Internet regarding this issue. May I suggest that DJI should develop a proper virtual simulator for hardware drones. Basically you would run it as a separate process that would simulate real drone via USB connection. This would help developers tremendously with developing new applications as currently the only way to debug and test functionality related to drone code is via real phone. As you can imagine this is quite cumbersome as it has to install the app every time. In the end it would save us all a lot of time and help development experience being more enjoyable.
