SDK Bridge is a developer tool that provides a bridge to connect an under development app running in the iOS simulator to a DJI product's remote controller. It's the missing link for a better workflow to create or debug your DJI Mobile SDK based apps. To use: 1/ Connect an Apple device to your remote controller 2/ Launch SDK Bridge 3/ Note the IP Address 4/ Transfer it to the parameter of the enableBridgeModeWithBridgeAppIP: method in DJISDKManager From then, your app behaves just like if it was connected directly to the physical remote controller.
