601 -Now, let's experiment with sending data to ThingsBoard using a real NB-IoT device. For example, we will use the **TS01-NB**.
602 -
603 -First, configure the NB-IoT device with the necessary MQTT settings using AT commands. Below is a list of AT commands you can use.
604 -
605 -
606 -**AT Commands**
607 -
608 -* **AT+PRO=3,3    **~/~/ Use MQTT to connect to ThingsBoard. Payload Type set to 3.
609 -* **AT+SUBTOPIC=<MQTT subscribe topic> **
610 -* **AT+PUBTOPIC=<MQTT publish topic> Eg: TS01-NB**
611 -* **AT+CLIENT=null**
612 -* **AT+UNAME=<MQTT Username>**
613 -* **AT+PWD=<MQTT Password>**
614 -* **AT+SERVADDR=<Broker address, Port>**
615 -
616 -Test your uplink by pressing the ACT button for 1 second.
617 -
618 -
619 -
620 -The following image shows the uplink payload of a real Dragino device. The publish topic is **TS01-NB**, and the device name is **861275077962896**, which is represented by the **IMEI**.
621 -
622 -{{info}}
623 -The ThingsBoard uses the device's IMEI number included in the payload to create a device in the Devices section.

372 +If the integration was performed without errors, after the transmission of the first telemetry, a new device with the name “S31B-NB” will appear in the Devices → All. Also, you can verify the input and output data, respectively, before and after conversion in Data converters → UDP Uplink Converter NB/CB → Events.
