Send net_fdm Packet to FlightGear

Transmit net_fdm packet to destination IP address and port for FlightGear session

Library

Animation/Flight Simulator Interfaces

Description

The Send net_fdm Packet to FlightGear block transmits the net_fdm packet to FlightGear on the current computer, or a remote computer on the network. The packet is constructed using the Pack net_fdm Packet for FlightGear block. The destination port should be an unused port that you can use when you launch FlightGear with the FlightGear command line flag:

--fdm=network,localhost,5501,5502,5503

The second port in the list, 5502, is the network flight dynamics model (fdm) port.

This block does not product deployable code.

Determining the Destination IP Address

You can use one of several techniques to determine the destination IP address, such as:

Use 127.0.0.1 for "this" computer

Ping another computer from a Windows^® cmd.exe (or UNIX^® shell) prompt:

C:\> ping andyspc
