# Satellite NTN Network [**Murata LBAD0XX1SC-DM**](https://www.murata.com/en-us/products/connectivitymodule/lpwa/overview/lineup/type-1sc) 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. ## Set up Murata Kit (LBAD0XX1SC-DM-EVK2) ![](https://3922449203-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M0mPxGpottOEfcucXOR%2Fuploads%2FsdbGp2xXJqGltGlIuFRl%2FMurata.jpeg?alt=media\&token=88973f41-7b9b-4499-a592-68d31fe247ef) ## Set up the EVK Kit * Connect the **UBC Cable** to the EVK kit. * **Connect the LTE antenna** * 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 %} #### **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" %} Example response: Revision: RK\_03\_02\_01\_00\_34531\_001 Revision: RK\_03\_02\_01\_00\_40041\_001 {% endhint %} Request the **IMSI** (International Mobile Subscriber Identity): ``` AT+CIMI ``` Request the **ICCID** (Integrated Circuit Card ID), which is the identification number of the iSIM ``` AT%CCID ``` Check the **SIM initialization selection policy** is currently using: ``` AT%GETCFG="SIM_INIT_SELECT_POLICY" ``` Expected response: `SIM_INIT_SELECT_POLICY:5`. The last digit indicates the Active SIM:\ 0 indicates **External (SIM card)**\ 5 indicates **Internal (iSIM)** **Enable** the External SIM card ``` AT%SETCFG="SIM_INIT_SELECT_POLICY","0" ``` #### **Reboot the Module**: ```bash ATZ ``` ### **Set the NTN Parameter** (enter the commands) Revision: RK\_03\_02\_01\_00\_34531\_001 ```bash AT%SETACFG="radiom.config.multi_rat_enable","true" AT%SETACFG="radiom.config.preferred_rat_list","none" AT%SETACFG="radiom.config.auto_preference_mode","none" AT%SETACFG="ntn.conf.gnss_in_use","egnss" AT%GETACFG="ntn.conf.gnss_in_use" AT%SETACFG="modem_apps.Mode.AutoConnectMode","true" ``` Revision: RK\_03\_02\_01\_00\_40041\_001 ```bash AT%SETACFG="radiom.config.multi_rat_enable","true" AT%SETACFG="radiom.config.preferred_rat_list","none" AT%SETACFG="radiom.config.auto_preference_mode","none" AT%GETACFG="ntn.conf.gnss_in_use" AT%SETACFG="modem_apps.Mode.AutoConnectMode","true" AT%NTNCFG="POS","MANUAL","1" ``` #### Define the NB-IoT NTN ``` AT%RATIMGSEL=2 AT%RATACT="NBNTN",1 ``` **Lock the modem to a specific region/band** ``` AT%SETCFG="BAND","255" ``` {% hint style="info" %} Although the modem may support many different NTN bands, 23 = Canada 255 = L band Global (Taiwan, Australia, New Zealand, Japan) 256 = S band Europe {% endhint %} **Reset** in order for the parameters to take effect ```bash ATZ ``` ### Network Activation **Disable** **radio** ```bash AT+CFUN=0 ``` **Set GPS location** Revision: RK\_03\_02\_01\_00\_34531\_001 ```bash AT%NTNCFG="FIX",LATITUDE,LONGITUDE,40,0 ``` Revision: RK\_03\_02\_01\_00\_40041\_001 ``` AT%NTNEV="POSREQ",1 AT%NTNCFG="POS","STAT","LATITUDE","LONGITUDE","160" ``` {% hint style="info" %} example AT%NTNCFG="FIX",33.998737,-84.095023,40,0 //RK\_03\_02\_01\_00\_34531\_001 AT%NTNCFG="POS","STAT","33.998737","-84.095023","160" //RK\_03\_02\_01\_00\_40041\_001 {% endhint %} **Set the APN to** `data.mono`: ```json AT+CGDCONT=1,"IP","DATA.MONO" ``` **Enable SIB31** reception notification: ```bash AT%NOTIFYEV="SIB31",1 ``` **Report** notification about Timing Advance calculation: Revision: RK\_03\_02\_01\_00\_34531\_001 ```bash AT%TADJEV=1 ``` Revision: RK\_03\_02\_01\_00\_40041\_001 ``` AT%NTNEV="TA",1 ``` **Enable RRC** State notification: ``` AT%NOTIFYEV="RRCSTATE",1 ``` **Send registration status** ``` AT+CEREG=2 ``` **Enable** **radio** ``` AT+CFUN=1 ``` Example response: Revision: RK\_03\_02\_01\_00\_34531\_001 ``` %NOTIFYEV: "SIB31",.... %TADJEVU: "TA",... %TADJEVU: "TAC",... +CEREG: 5,"07ED",.... ``` Revision: RK\_03\_02\_01\_00\_40041\_001 ``` %NOTIFYEV: "SIB31",.... %NTNEVU: "TA","RACH"... %NTNEVU: "TA","TAC".... %NOTIFYEV: "RRCSTATE",... +CEREG: 5,"07D4",.... ``` ## Test the connection by sending a UDP payload {% 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** ``` AT%SOCKETCMD="ALLOCATE",1,"UDP","OPEN","", ``` Example message: `AT%SOCKETCMD="ALLOCATE",1,"UDP","OPEN","34.192.142.126",12345` Example response: `%SOCKETCMD:1` ### **2. Activate Socket** ``` AT%SOCKETCMD="ACTIVATE",1 ``` Example response: `%SOCKETCMD:1` ### **3. Send UDP data** ``` AT%SOCKETDATA="SEND",1,,"" ``` Example message: `AT%SOCKETDATA="SEND",1,13,"48656C6C6F2C20776F726C6421"` Example response: `%SOCKETDATA:1,13` {% 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. {% endhint %} **Request info UDP Socket** ``` AT%SOCKETCMD="INFO",1 ``` Example response: `%SOCKETCMD:"ACTIVATED","UDP","10.22.243.30","34.192.142.126",12345,7` ### **4. Close UDP socket** End your UDP session by closing the UDP socket. ``` AT%SOCKETCMD="DELETE",1 ``` Expected response: `OK` ## Test UDP Payload with Ubidots To quickly test if UDP messages are successfully sent, you can use a platform like **Ubidots**.
