UDP Output

Note: This feature is implemented in Silent Wings 1.08. It will not work with earlier versions

Silent Wings can output various flight data to a configurable UDP socket. This can be useful for add-on developers and cockpit builders. Specifically, we support the Simkits protocol for output of flight data to SimKits instrument panels. In addition, we support the Condor format and our own binary format.

use_output_udp      = false
output_udp_protocol = simmeters
output_udp_address  = localhost
output_udp_port     = 6060
output_udp_rate     = 30

• • Simkits Protocol **

• • Condor Protocol **

• • Binary Protocol **

The binary protocol is the most compact, and gives the best precision, but can be harder to program and debug.
