TOPIC ID


  • We use QoS 1 and saw that the Topic Registration ID has changed.

    1. What is the criteria for assgining the Topic Registration ID ?

    2. Why there is no error if using a non existing Topic ID



    1. Due to limited number of possible Topic ID’s the assigment is dynamic. Therefore it is needed to REGISTER each time after new connection.

    2. The reason for that is that it would be possible to make Topic Scan. By doing this the creation of Topic profiles would be possible which should be avoided
