YSF Direct Protocol[edit]

The target of this protocol is to allow users to connect their SystemFusion YSF-enabled hotspots and repeaters directly to BrandMeister.

YSF Direct is an extension to existing YSF reflector protocol.

Unused characters in callsign field should be filled with NULL or space characters.

Login procedure[edit]

  1. User -> Server: "YSFL" <10 characters of hotspot/repeater callsign>
  2. Server -> User: "YSFACK" <10 characters of server callsign> <4 bytes of salt>
  3. User -> Server: "YSFK" <10 characters of hotspot/repeater callsign> <32 bytes of SHA256(salt + password)>
  4. Server -> User: "YSFACK" <10 characters of server callsign>

In case of failure: "YSFNAK" <10 characters of server callsign> <4 bytes of salt>

Change assigned talk group[edit]

The message can be sent anytime when hotspot/repeater connected and authenticated. So main purpose for it is to change talk group. We suggest a YSF developers to add it into configuration settings as well to Wires-X menu.

  1. User -> Server: "YSFO" <10 characters of hotspot/repeater callsign> "group=" <ASCII string contains a talk group number (NULL-termination is optional)>
  2. Server -> User: "YSFACK" <10 characters of server callsign>

In case of failure: "YSFNAK" <10 characters of server callsign>
