Sync call without receiver

Hello,

we want to set up a scenario, that is more a PING on XI than a real scenario:

In detail:

a special application should send a SYSC request, to check if XI is online.

XI sould response sync with a message.

Because of a missing receiver, I am not sure how to set up this scenario.

Do I have to use the sync-async bridge with BPM or do you have any workaround?

Regards Mario
