I try to figure out how cayenne works in MQTT communication. So i look for MQTT API page. Before doing “coding” i tried to check MQTT API using MQTT lens. Everything was OK, client can connected but somehow every time i publish as API manual, it lost communication.
Here i tried publish topic “v1/my-username-123/things/my-client-id-1234/sys/model” and put “Wemos Mini D1” as value.
Can you help me what’s going on? Either i try another, connection always lost.
