TIMEOUT_MS: DDS ping timeout

Description

The time in milliseconds the DDS client will wait for a response from the XRCE agent before reattempting.

Values

• Range: 1 to 10000
• Units: ms
• Default: 1000

Description

This parameter manages the connection timeout for the DDS (Data Distribution Service) interface, typically used for ROS 2 integration.

• Function: The autopilot (DDS Client) periodically pings the companion computer (XRCE Agent). If no response is received within this time limit, the client assumes the connection is lost and attempts to reconnect.
• Usage: Adjust this based on the latency and reliability of your serial or Ethernet link to the companion computer.
• Tuning: If you have a slow or congested network, increase this to prevent spurious disconnects.
