Murata LBAD0XX1SC-DM

### Prerequisites * Monogoto SIM * [LBAD0XX1SC-DM](https://www.murata.com/en-us/products/connectivitymodule/lpwa/overview/lineup/type-1sc) ### Quick Navigation * [Test the connection by sending a PING](#test-the-connection-by-sending-a-ping) * [Useful Links](#useful-links) ## Connect the LBAD0XX1SC to Monogoto {% 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 %} **Define the Cat-M1** ``` at%ratimgsel=1 ``` #### **Reset the Module**: Reset non-volatile memory: Reboot module: ```bash ATZ ``` **Set the error reporting to verbose**, resulting in more descriptive error messages (optional): ```bash AT+CMEE=2 ``` Check the **status of the SIM card**. The correct response should be: `+CPIN: READY` ``` AT+CPIN? ``` {% hint style="warning" %} If you receive an error, the SIM may not be inserted properly or the SIM is protected with a PIN. By default, Monogoto SIMs are not PIN-protected. {% endhint %} ### Query device information Request the **product type, hardware,** and **firmware** **version**: ```bash ATI ``` Request the **IMSI** (International Mobile Subscriber Identity): ``` AT+CIMI ``` ### Network Configuration It is possible to let the modem select the network automatically, or to manually define a network to connect with. #### **Option 1: Automatic Network Selection** To set the modem to **automatic network selection** enter the command: ```bash AT+COPS=0 ``` Check the **network and cellular technology the modem** is currently using: ``` AT+COPS? ``` Expected response: `+COPS: 0,0,"",X`. The last digit indicates the cellular technology:\ 7 indicates **LTE Cat-M1**\ 8 indicates **NB-IoT** #### Option 2: Manual Network Selection Start with searching for available networks: ``` AT+COPS=? ``` {% hint style="warning" %} It may take several minutes before the modem responds. {% endhint %} The modem responds with the **names** and the **MCCMNC** codes of the available networks. It also shows the cellular technologies the networks support: ``` +COPS: (1,"vodafone NL","voda NL","20404",8),(1,"NL KPN","NL KPN","20408",0),(1,"vodafone NL","voda NL","20404",9),(1,"T-Mobile NL","TMO NL","20416",0),(1,"NL KPN","NL KPN","20408",8),(1,"vodafone NL","voda NL","20404",0),(1,"T-Mobile NL","TMO NL","20416",8),(1,"T-Mobile NL","TMO NL","20416",9),,(0,1,2,3,4),(0,1,2) OK ``` To find which of the networks Monogoto has **roaming agreements** with, review the [**Coverage lists**](https://docs.monogoto.io/getting-started/global-public-coverage). {% hint style="info" %} To find the **profile** of your SIM, visit the [**Monogoto Console**](https://console.monogoto.io/), open the page **Things** ![](https://3922449203-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M0mPxGpottOEfcucXOR%2Fuploads%2FfH8DCNlIW5R2VRiHwMG5%2FThings.png?alt=media\&token=2a63b922-cb41-4271-803e-ba9eab36566d) and select a specific **Thing**. Scroll down to **Mobile Identities** to find your profile in the column **Network Provider Name**. ![](https://3922449203-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M0mPxGpottOEfcucXOR%2Fuploads%2FddQeceTZxjtQYFPAHe95%2Fimage.png?alt=media\&token=4a3f1cbf-3922-48f9-af5d-2e292bd76b72) {% endhint %} Check the **network and cellular technology** the modem is currently using: ``` AT+COPS? ``` Expected response: `+COPS: 0,0,"",X`. The last digit indicates the cellular technology. **Manually set the network and the cellular technology**: ``` AT+COPS=1,2,"XXXXX",7 ``` Replace `XXXXX` with the **MCCMNC** code of your operator, for example`"20404"` for Vodafone NL. Use `7` for LTE Cat-M1. **Check the radio signal strength and signal quality:** ```bash AT+CSQ ``` {% hint style="info" %} `+CSQ` returns 2 values separated by a comma. The first value represents the **signal strength** and provides a value between 0 and 31; higher numbers indicate better signal strength. The second value represents the **signal quality** indicated by a value between 0 and 7. If `AT+CSQ` returns `99,99`, the signal is undetectable or unknown. {% endhint %} #### Define the cellular band(s) (optional) It is possible to **lock the modem to one or more specific bands**. This may result in a faster boot cycle as the modem does not need to scan for available bands at startup. {% hint style="info" %} Support LTE Band: Low Bands 5,8,12,13,14 (CAT M1 Only),17,18,19,20,26,28 Mid Bands 1,2,3,4,25 {% endhint %} {% hint style="warning" %} Although the modem may support many different bands, your local network operator may not. Have a look at the [**LTE Cat-M1 overview**](https://docs.monogoto.io/getting-started/general-device-configurations/iot-devices/broken-reference) to find the available band(s) in your region. {% endhint %} To lock the modem to a specific band, a hexadecimal value representing the band needs to be sent to the modem. To **lock the modem to LTE-M band 5**, send: ``` AT%SETCFG="BAND","5" ``` {% hint style="info" %} For information about setting specific LTE bands, see **Murata LBAD0XX1SC-DM** **AT Commands Manual**, chapter **4.2.5.** {% endhint %} To test if the band(s) is properly set, enter the command: ``` AT%GETCFG="BAND" ``` Example response: Bands: 1 ,2 ,3 ,4 ,5 ,8 ,12 ,13 ,14 ,17 ,18 ,19 ,20 ,25 ,26 ,28\ They represent the LTE-M bands and NB-IoT bands. #### Query Network information To information about the technology used, the network provider, and the cellular band, enter: ``` AT+QNWINFO ``` Example response: `+QNWINFO: "eMTC","20408","LTE BAND 20",6400`. ### Network Activation **Set the APN to** `data.mono`: ```json AT+CGDCONT=1,"IP","data.mono" ``` Validate if the **APN** is set correctly: ``` AT+CGDCONT? ``` Expected response: `+CGDCONT: 1,"IP","data.mono","0.0.0.0",0,0,0,0,0,0` **Activate the PDP (packet data protocol) context**: ``` AT+CGACT=1,1 ``` **Test** if the PDP context is activated: ``` AT+CGACT? ``` Expected response: `+CGACT: 1,1` #### Validate if your device received an **IP address**: ```bash AT+CGPADDR ``` Expected response: `+CGPADDR: 1,XX.XXX.XX.XXX` {% hint style="info" %} Do you see an IP address? **Congratulations! You’ve successfully connected the Murata LBAD0XX1SC-DM modem to Monogoto 🎉** {% endhint %} ## Test the connection by sending a PING A PING test can be performed to test if the modem has an active data connection with a mobile network. {% hint style="warning" %} When cellular modems are idle for a long period of time, cell towers might drop the data connection to save resources. Sending regular PINGs is a good method for testing the data connection, as well as for keeping the connection alive because the operator registers your device as being actively used. {% endhint %} **Send 5 PINGs** to the IP address `8.8.8.8`: ``` AT%PINGCMD=0,"8.8.8.8",5 ``` Example response: ``` +QPING: 0,"8.8.8.8",32,543,255 +QPING: 0,"8.8.8.8",32,396,255 +QPING: 0,"8.8.8.8",32,262,255 +QPING: 0,"8.8.8.8",32,299,255 +QPING: 0,4,4,0,262,543,375 ``` {% 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 %} ## Useful Links * [QLBAD0XX1SC-DM product page](https://www.murata.com/en-us/products/connectivitymodule/lpwa/overview/lineup/type-1sc#anchor-3) * [QLBADXX1SC-DM Quick Start Guide](https://3922449203-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M0mPxGpottOEfcucXOR%2Fuploads%2FIQSItX6iyZ35t7a1wnVf%2FLPWA%20Type%201SC%20Quick%20start%20guide_Ver3%201.pdf?alt=media\&token=f8493020-a0a8-4e34-afb8-246540645017) * [QLBADXX1SC-DM DataSheet](https://wireless.murata.com/pub/RFM/data/lbad0xx1sc.pdf)
