++First you need to configure the certificate to the -NB node. Follow the instructions in this **[[link>>url:https://wiki.dragino.com/xwiki/bin/view/Dragino%20NB%20device%20connection%20to%20AWS%20platform%20instructions/#H4.1.2Configurecertificate]]** to configure the certificate.

--
--Now, let's experiment with sending data to Thingseye using a real NB-IoT device. For example, we will use the **TS01-NB**.
--
--First, configure the NB-IoT device with the necessary MQTT settings using AT commands. Below is a list of AT commands you can use.
--
--**AT Commands**
--
--* **AT+PRO=3,3    **~/~/ Use MQTT to connect to Thingseye. Payload Type set to 3.
--* **AT+SUBTOPIC=<MQTT subscribe topic> Eg: TS01-NB**
--* **AT+PUBTOPIC=<MQTT publish topic> Eg: TS01-NB**
--* **AT+CLIENT=null**
--* **AT+UNAME=<MQTT Username>**
--* **AT+PWD=<MQTT Password>**
--* **AT+SERVADDR=<Broker address, Port>**
--
--Test your uplink by pressing the ACT button for 1 second.
--
--
--The following image shows the uplink payload of a real Dragino device. The publish topic is '**TS01-NB' that contains fields in the payload, IMEI, IMSI, Model, temperature, etc**. Note that we have created a device named **TS01-NB** in the **Devices** section in advance.
