Murata Type 1SC-NTN LBAD0XX1SC - Evaluation Kit

Built on 3GPP Release-17 NTN standards, the Murata Type 1SC-NTN module brings satellite IoT capabilities to your devices—without requiring hardware changes. In partnership with Skylo, Murata enables reliable NTN communication for remote and hard-to-reach areas.

This guide provides step-by-step instructions to set up the Murata Type 1SC-NTN LBAD0XX1SC Evaluation Kit using a Velocity IoT SIM, including how to configure AT commands for Skylo Satellite IoT connectivity over Non-Terrestrial Networks (NTN).

How to Connect

Before attempting to connect, ensure your SIM is active in the CMP and that a data plan has been assigned. For any issues related to your account or SIM activation, please contact support@velocityiot.com

  • Connect the USB cable to your PC and the EVK board via the AT CMD port (Mini USB).
  • Insert your Velocity IoT SIM into the SIM slot on the EVK.
  • Connect the Antena

The EVK is now powered and ready for serial communication.

Set Up Serial Connection

  • On Windows, install the USB-to-Serial driver:

CP210x VCP Driver – Silicon Labs

  • Open a terminal tool

Windows: Tera Term or PuTTY

Mac/Linux: screen, minicom, or Miniterm

  • Configure the Terminal:

Baud rate: 11520

Data bits: 8

Parity: None

Stop bits: 1

Flow control: None

  • Press Enter, then Type AT. If the connection is successful, you will see OK

Test The Connection by Sending a UDP Payload

Once your Murata Type 1SC module is registered on the Skylo NTN network and has completed GPS/location setup, you can test end-to-end connectivity by sending a UDP packet using a socket-based AT command sequence.

The module uses a set of AT%SOCKETCMD and AT%SOCKETDATA commands to allocate, activate, send, and clean up a UDP session.


Allocate a UDP Socket

Start by allocating a UDP socket to the IP address and port of your destination server. Replace  <destination_ip> and <port> with actual values.

AT%SOCKETCMD="ALLOCATE",1,"UDP","OPEN","<destination_ip>",<port>

For example, to send to Google's public DNS server (just for test routing purposes), you could use:

AT%SOCKETCMD="ALLOCATE",1,"UDP","OPEN","8.8.8.8",1234

Replace 8.8.8.8 and 1234 with your server’s IP address and port.


Activate the Socket

After the socket is allocated, you need to activate it before sending any data:

AT%SOCKETCMD="ACTIVATE",1

Send a UDP Payload

Now send a test payload using the AT%SOCKETDATA command. The payload must be in hexadecimal format, and you must specify the length of the data in bytes.

AT%SOCKETDATA="SEND",1,,"<hex_payload>"

Example

AT%SOCKETDATA="SEND",1,13,"48656C6C6F2C20776F726C6421"

Verify Socket Status

AT%SOCKETCMD="INFO",1

Close UDP Socket

After your test is complete end your UDP session by closing the socket

AT%SOCKETCMD="DELETE",1
