  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.
--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.
++The Mosquitto client publishes messages (payloads) on the topic **v1/devices/me/telemetry**. Of course, you can use any topic for testing.
--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.
++(% id="cke_bm_37386S" style="display:none" %) (%%)The MQTT payload format is as follows, which is common for all **~-~-NB** and **~-~-CB** series devices. The **IMEI** field is mandatory and is used to provision a new device with the name assigned to it in ThingsBoard.
--
--**The new device is created the first time the MQTT topic is received. For subsequent MQTT topics with the same device name, no duplicate devices will be created.**

--For example, if you send two MQTT messages with different device names in the topic:
--
--1. v1/devices/**S31B-NB**/telemetry
--1. v1/devices/**LDS25-NB**/telemetry
