To download the latest version, [**click here**](https://m2m-communication.gemalto.com/Thales-TX62-ATC). {% endhint %} **Reset the modem** to its factory default configuration: ```bash AT&F ``` Set the error reporting to **verbose**, resulting in more descriptive error messages (optional): ```bash AT+CMEE=2 ``` Check if the SIM card is attached and is not locked with a PIN, expected response: `+CPIN: READY`: ```bash 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** number: ```bash ATI ``` Expected response: `Cinterion TX62-W REVISION 01.001` Request the **IMSI** (International Mobile Subscriber Identity): ``` AT+CIMI ``` Request the **ICCID** (Integrated Circuit Card ID), which is the identification number of the SIM card ```bash AT^SCID ``` ### 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** \ `9` 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: Example response: ``` +COPS: (2,"NL KPN","NL KPN","20408",7),(1,"T-Mobile NL","TMO NL","20416",7),(1,"vodafone NL","voda NL","20404",9),,(0,1,2,3,4),(0,1,2) ``` 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 %} #### Selection of Radio Access Technology (RAT) The `AT^SXRAT` command specifies the Radio Access Technologies to be used for network selection and registration. To set a preferred technology, use: ``` AT^SXRAT=, ``` Replace `` with:\ `7` for **LTE-M**\ `8` for **NB-IoT**\ `10` for **LTE-M and NB-IoT** Replace `` to define an preferred radio technology (optional):\ `7` for **LTE-M**\ `8` for **NB-IoT** *Example:*\ To enable both LTE-M and NB-IoT, and use LTE-M as the preferred RAT, use: ``` AT^SXRAT=10,7 ``` **Test** if the RAT selection is properly set: ``` AT^SXRAT? ``` #### 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. To **find** the bands the modem has currently enabled for CatM, use: ``` AT^SCFG="Radio/Band/CatM" ``` Expected response: ``` AT^SCFG="Radio/Band/CatM",0f0e189f,10000200000000 ``` *`0f0e189f,10000200000000` indicates that all available bands are enabled.* To **find** the bands the modem has currently enabled for NB-IoT, use: ``` AT^SCFG="Radio/Band/CatNB" ``` {% hint style="warning" %} Although the modem may support many a variety of 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 CatM band: \ \&#xNAN;*Replace `` with your band of choice. E.g. `80000` represents band 20.* ``` AT^SCFG="Radio/Band/CatM", ``` To **lock** the modem to a specific NB-IoT band: ``` AT^SCFG="Radio/Band/CatNB", ``` {% hint style="info" %} To find out more details about **what** **values represent what bands**, visit the [**Cinterion AT Commands Manual**](https://m2m-communication.gemalto.com/Thales-TX62-ATC), section 2.11, page 63-65 {% endhint %} **Test** if the Cat-M1 band is properly set: ``` AT^SCFG="Radio/Band/CatM" ``` Example response: `^SCFG: "Radio/Band/CatM","0f0e189f","0010000200000000"` To test the NB-IoT band, use: ``` AT^SCFG="Radio/Band/CatNB" ``` ## 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` To **test** what cellular technology and what band the modem is using, request the **network information** from the serving cell: ``` AT^SMONI ``` Example response: ``` ^SMONI: Cat.M1,6400,20,-,FDD,204,08,7919,028E70D,331,40,-86,-11,NOCONN,12 ``` The first variable `Cat.M1` indicates the cellular technology used. The third variable `20` indicates the current frequency band. #### Validate if your device received an **IP address**: ```bash AT+CGPADDR ``` Expected response: `+CGPADDR: 1,XX.XXX.XX.XXX` {% hint style="success" %} Do you see an IP address? **Congratulations! You’ve successfully connected the Cinterion TX62 modem to Monogoto 🎉** {% endhint %} ## 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 %} Start by **activating the Internet service connection** for PDP context 1: ``` AT^SICA=1,1 ``` To use PDP context 1 to send 5 PINGs to IP address `8.8.8.8` with a timeout of 5000 milliseconds, use: ``` AT^SISX=Ping,1,"8.8.8.8",5,5000 ``` If the connection is active, you will see 5 PINGs with a number representing the response time in milliseconds. Example response: ``` ^SISX: "Ping",1,1,"8.8.8.8",306 ^SISX: "Ping",1,1,"8.8.8.8",151 ^SISX: "Ping",1,1,"8.8.8.8",176 ^SISX: "Ping",1,1,"8.8.8.8",142 ^SISX: "Ping",1,1,"8.8.8.8",85 ``` {% hint style="success" %} **Great work on connecting the Cinterion TX62 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 * [Cinterion Product page](https://www.thalesgroup.com/en/markets/digital-identity-and-security/iot/iot-connectivity/products/iot-products/tx62) * [Cinterion AT Commands](https://m2m-communication.gemalto.com/Thales-TX62-ATC)
