Available subscriptions on rejoined session

[HansHabraken]

Hi Team

I observed that resubscribing to a topic is not needed when the client rejoins an existing session where a subscribe call has already been taken place. How can the client know which subscriptions are active for the rejoined session?

Upon successful connection to the broker, a OnConnectionSuccessReturn object is returned, but this object does not contain any information about the already active subscriptions.

Thanks in advance.

Kind Regards
Hans

All of your subscriptions will be active if you rejoin a session.

Oke, but lets say I want to know what the active subscriptions were. Is this communicated from the broker to the client?

No, MQTT does not provide that information.
