  • Send net_fdm Packet to FlightGear block

Libraries:
Aerospace Blockset / 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

This block does not produce deployable code.

FlightGear net_fdm data packet, specified as a scalar.

Data Types: uint8

Parameters

Destination IP address, specified as a scalar.

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

  • Use 127.0.0.1 for the local computer

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

    C:\> ping andyspc
