388 388  We use the Mosquitto MQTT client to simulate MQTT messages, acting as a virtual device. First, install the Mosquitto client on your computer from [[this link>>url:https://mosquitto.org/download/]]. The Mosquitto client publishes messages to the MQTT broker (HiveMQ) on a specified MQTT topic. ThingsBoard subscribes to these messages using the same topic.
389 389  
390 -The Mosquitto client publishes messages on the topic v1/devices/[device_name]/telemetry. The [device_name]placeholder can be replaced with any device name, for example, 'S31B-NB'. Then, the MQTT topic would be v1/devices/S31B-NB/telemetry.
505 +The Mosquitto client publishes messages (payloads) on the topic **v1/devices/me/telemetry**. Of course, you can use any topic for testing.
391 391  
392 -On the ThingsBoard side, we configure the MQTT topic subscription as v1/devices/+/telemetry. The + wildcard represents any device name and allows ThingsBoard to automatically create (provision) a device with that name, such as S31B-NB, for example.
