## Set up the EVK Kit

* Connect the **UBC Cable** to the EVK kit.&#x20;
* **Connect the LTE antenna**&#x20;
* Insert the **Monogoto SIM**

#### **Connect your PC to the EVK Kit**

Use the USB to connect your computer to the **AT CMD** port of the EVK Kit

{% hint style="info" %}
When using Windows, install the driver using the disk or USB stick provided by Murata.
{% endhint %}

Connect to the EVK kit using a **terminal program**. You can use PuTTY for Windows, or Screen, minicom, or Miniterm for Mac or Linux.

Set the baud rate to **115200** Enter **`AT`**, if the connection with the LBAD0XX1SC-DM modem has been established, the board will answer with `OK`.

## Connect the LBAD0XX1SC to Skylo

{% hint style="info" %}
Keep the **AT Commands manual** next to you for more details about the commands. [**Click here**](https://www.murata.com/en-us/products/connectivitymodule/lpwa/overview/lineup/type-1sc) to download the latest version, and scroll down to **Documentation and Resources** to find the AT Commands Manual.
{% endhint %}

{% hint style="danger" %}
For some firmware versions, you need to click and hold the `SW1` button in order to send AT Commands to the module.
{% endhint %}

#### **Reboot the Module**:

```bash
ATZ
```

Check the **status of the SIM card**. The correct response should be: `+CPIN: READY`

```
AT+CPIN?
```

{% hint style="success" %}
+CPIN: READY means that the SIM is ready for use and does not require any PIN entry.
{% endhint %}

### Executing Commands by Version

Execute various commands based on the software version you are using. Make sure to execute the commands that correspond to your version.

**Query device information**

Request the **product type, hardware,** and **firmware** **version**:

```bash
ATI
```

{% hint style="warning" %}

Request the **IMSI** (International Mobile Subscriber Identity):

```
AT+CIMI
```

Request the **ICCID** (Integrated Circuit Card ID), which is the identification number of the iSIM&#x20;

```
AT%CCID
```

Check the **SIM initialization selection policy** is currently using:

```
AT%GETCFG="SIM_INIT_SELECT_POLICY"
```

Expected response:

## Test the connection by sending UDP payload&#x20;

{% hint style="warning" %}
When using Non-Terrestrial Networks, data can only be sent using UDP.
{% endhint %}

In order to send data using UDP, 4 AT Commands needs to be sent:

1. **Create UDP socket**
2. **Activate socket**
3. **Send UDP data**
4. **Close UDP Socket**

### **1. Create UDP socket**&#x20;

```
AT%SOCKETCMD="ALLOCATE",1,"UDP","OPEN","<ip address>",<port> 
```

Example message: <mark style="color:red;">`AT%SOCKETCMD="ALLOCATE",1,"UDP","OPEN","34.192.142.126",12345`</mark>

Example response: <mark style="color:red;">`%SOCKETCMD:1`</mark>

### **2. Activate Socket**&#x20;

```
AT%SOCKETCMD="ACTIVATE",1
```

Example response: <mark style="color:red;">`%SOCKETCMD:1`</mark>

### **3. Send UDP data**&#x20;

```
AT%SOCKETDATA="SEND",1,<length>,"<data>"
```

Example message: <mark style="color:red;">`AT%SOCKETDATA="SEND",1,13,"48656C6C6F2C20776F726C6421"`</mark>

Example response: <mark style="color:red;">`%SOCKETDATA:1,13`</mark>

{% hint style="warning" %}
Make sure to exactly count the number of characters you send, or you will receive an error.
{% endhint %}

{% hint style="danger" %}
It' s not possible to send text to the module, instead we need to send hexadecimal values. Convert possible text string to hexadecimal numbers using a program like [rapidtables](https://www.rapidtables.com/convert/number/ascii-to-hex.html).
{% endhint %}

{% hint style="info" %}
It may take up to 10 seconds for the message to be fully processed.&#x20;
{% endhint %}

**Request info UDP Socket**

```
AT%SOCKETCMD="INFO",1
```

Example response: <mark style="color:red;">`%SOCKETCMD:"ACTIVATED","UDP","10.22.243.30","34.192.142.126",12345,7`</mark>

### **4. Close UDP socket**

End your UDP session by closing the UDP socket.

```
AT%SOCKETCMD="DELETE",1
```

Expected response: <mark style="color:red;">`OK`</mark>

## Test UDP Payload with Ubidots

To quickly test if UDP messages are successfully sent, you can use a platform like **Ubidots**.

Learn more in our Ubidots guide:  [Ubidots](/developer/cloud-integrations/ubidots.md)

{% hint style="success" %}
**Great work on connecting the Murata LBAD0XX1SC-DM to Monogoto!** Have a look at the **Things** logs in the [**Monogoto Console**](https://console.monogoto.io/) to find more details about the established connection.
{% endhint %}
