Open Source SDK for iOS, macOS, watchOS and tvOS to communicate with X-Plane flight simulator via UDP interface. The SDK is written primarily in C++11 to be kept mostly platform independent.
FKTConnection- Objective-C wrapper to establish a connection to Xplane from any Apple OS platform.XplaneConnection- Main C++ component for establishing a network connection to Xplane.DataRecording- Stream listener for capturing flight data in a Sqlite database.
X-Plane offers a simple UDP data stream interface. A reference of the data format can be found here. To start sending
and receiving data in X-Plane, go to Settings --> DataOutput and check Send network data output. Enter an IP to send data to (the computer listening to the data
stream) as well as the port to send to. To start reading data as it comes in, open a FKTConnection via - (nonnull id) initReceivingOn:(NSInteger) inPort.
To be able to send data to X-Plane you will further have to make sure that the Port we receive on in Settings --> Network is set to 49000 or make sure that you call
- (nonnull id) initReceivingOn:(NSInteger)inPort sendingTo: (NSInteger)outPort with outPort set to the port next to Port we receive on.
To let FlightKit actively request aircraft data from X-Plane (recommended), you can use
- (nonnull id) initWithIP:(nullable NSString *)ip receivingOn: (NSInteger)inPort sendingTo: (NSInteger)outPort. The IP you enter will be the IP
of the computer running X-Plane, inPort the port set in Data Output and outPort the Port we receive on in Network.
Once FlightKit has connected to X-Plane, it will trigger a sound snippet in the flight simulator to indicate the connection.
