Description
- [x] Bug exists Release Version 1.2.5 ( Master Branch)
- [x] Bug exists in MQTTv3 Client on Snapshot Version 1.2.6-SNAPSHOT (Develop Branch)
- [ ] Bug exists in MQTTv5 Client on Snapshot Version 1.2.6-SNAPSHOT (Develop Branch)
The method **_Token.waitForCompletion()_** will only handle the type of message that has a response, and will not work on the type publish message because it has no response
I looked through the code again and found that the **_qos=0_** message was to be sent using **_MqttTopic_**. Whether this is ambiguous to the consumer, it is recommended to adapt **_MqttClient.publish()_** to the _**qos=0**_ message
