The Type 1SC module is the world’s smallest Cat. M1/NB-IoT module with global certification. It supports GPS/GNSS, OpenMCU, and Integrated SIMS.
Connect the UBC Cable to the EVK kit.
Connect the LTE antenna
Insert the Monogoto SIM
Use the USB to connect your computer to the AT CMD port of the EVK Kit
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
.
For some firmware versions, you need to click and hold the SW1
button in order to send AT Commands to the module.
Check the status of the SIM card. The correct response should be: +CPIN: READY
+CPIN: READY means that the SIM is ready for use and does not require any PIN entry.
Execute various commands based on the software version you are using. Make sure to execute the commands that correspond to your version.

When using Non-Terrestrial Networks, data can only be sent using UDP.
In order to send data using UDP, 4 AT Commands needs to be sent:
Create UDP socket
Activate socket
Send UDP data
Close UDP Socket
Example message: AT%SOCKETCMD="ALLOCATE",1,"UDP","OPEN","34.192.142.126",12345
Example response: %SOCKETCMD:1
Example response: %SOCKETCMD:1
Example message: AT%SOCKETDATA="SEND",1,13,"48656C6C6F2C20776F726C6421"
Example response: %SOCKETDATA:1,13
Make sure to exactly count the number of characters you send, or you will receive an error.
Request info UDP Socket
Example response: %SOCKETCMD:"ACTIVATED","UDP","10.22.243.30","34.192.142.126",12345,7
End your UDP session by closing the UDP socket.
Expected response: OK
To quickly test if UDP messages are successfully sent, you can use a platform like Ubidots.

Keep the AT Commands manual next to you for more details about the commands. to download the latest version, and scroll down to Documentation and Resources to find the AT Commands Manual.
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 .
Great work on connecting the Murata LBAD0XX1SC-DM to Monogoto! Have a look at the Things logs in the to find more details about the established connection.
