Connecting to the drone
Connection profiles
Harlock uses connection profiles saved locally. Each profile contains:
- Protocol (UDP / TCP)
- IP address and port
- Descriptive name
SIYI connection
The default SIYI profile connects to the SIYI datalink (192.168.144.20:19856, the standard address for HM30/MK32 links) through the internal relay. Enable it from the SIYI profile's connect button in Connection settings.
Multi-GCS sharing (integrated relay)
The SIYI profile uses an in-app MAVLink relay that lets multiple ground stations share the same SIYI link at the same time. Enable the SIYI profile on each station: the nodes automatically elect a single master (the sole client of the SIYI link) that fans telemetry out to the others. No external process and no manual peer configuration are needed. See the Multi-GCS relay guide.
