I’m having problems with this myself. Maybe your are like me having a missing binding? If you open a terminal on the target and do “sdir list” you get a list of services and waiting clients.
Although how to then bind them correctly to each other I don’t know. According to https://forum.legato.io/t/low-level-messaging-api/2589/2 in the client adef file something like
bindings:
{
*.ClientName -> ServerProcess.ServerInterface
}
Is required, but I haven’t gotten it working yet…
