## Set up EVB Kit (if applicable)
#### Set up the EVB Kit
* Connect the **Quectel BG95-S5 modem** to the EVB kit.
* **Connect the LTE antenna** and **GPS antenna**
* Insert the **Monogoto SIM**
#### **Connect your PC to the EVB Kit**
Use the USB to UART converter cable to connect your computer to the **COM1 MAIN** port of the EVB Kit
{% hint style="info" %}
When using Windows, install the driver using the disk or USB stick provided by Quectel.
{% endhint %}
Connect to the EVB kit using a **terminal program**. You can use PuTTY for Windows, or screen, minicom, or miniterm for Mac or Linux.
**Power the EVB Kit** using the USB to micro USB cable and switch the **POWER** button to **ON**. The **POWER LED** will turn on **RED**.
Press and hold the **PWRKEY** button for 1 second, the **STATUS** light will light up on **GREEN**, the **NET\_STA** LED will start blinking **BLUE**.
Once the modem has started, it will report:
```
RDY
APP RDY
```
Enter `AT`, if the connection with the BG95 modem has been established, the board will answer with `OK`.
## Connect the BG95 to Monogoto
{% hint style="info" %}
Keep the **AT Commands manual** next to you for more details about the commands. [**Click here**](https://files.gitbook.com/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M0mPxGpottOEfcucXOR%2Fuploads%2FLLImiasYlmYZUHjxOdMA%2FQuectel_BG95-S5_AT_Commands_Manual_V1.0.pdf?alt=media\&token=b9d0c858-4a7e-4f06-9509-2af39fc6359d) to download the latest version.
{% endhint %}
#### **Reset the modem** to its default configuration:
Reset non-volatile memory:
```
AT+QPRTPARA=1
```
Restore factory settings:
```
AT+QPRTPARA=3
```
Reboot module:
```bash
AT+CFUN=1,1
```
**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**:
AT+QGMR
Example response: AT+QGMR BG95S5LAR08A01\_A0.203.A0.203
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+CCID
```
### Network Configuration
It is possible to let the modem select the network automatically.
#### **Automatic Network Selection**
To set the modem to **automatic network selection** enter the command:
```bash
AT+COPS=0
```
#### Configure Radio Access Technology (RAT)
Configure the modem to only use NB-IoT NTN not LTE Cat-M1:
```
AT+QCFG="iotopmode",3
AT+QCFG="nwscanmode",3
```
**Set the APN to** `data.mono`:
```json
AT+CGDCONT="IP","data.mono" or AT+CGDCONT=1,"IP","data.mono"
```
**Lock the modem to a specific region/band**
```
AT+QCFG="band",0xf,0x100002000000000f0e189f,0x10004200000000090e189f,0x1,1
```
{% hint style="info" %}
Although the modem may support many different NTN bands,
**0x1** = 23 Canada
**0x2** = 255 L band Global (Taiwan, Australia, New Zealand, Japan)
**0x4** = 256 S band Europe
{% endhint %}
#### Query Network information
To information about the technology used, the network provider and cellular band, enter:
```
AT+QNWINFO
```
Example response: `+QNWINFO:"NTN NBIoT","90198","NTN NBIoT BAND 23",229155`
#### **Reports the information of serving cells**
```bash
AT+QENG="servingcell"
```
Example response:
+QENG: "servingcell","LIMSRV","NTN NBIoT","FDD",901,98,2DCEAE,30,7699,23,0,0,7EE,-120,-13,-115,85,
**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 %}
**Check the current network registration status**
```
AT+CEREG?
```
response:
```
+CEREG: 2,5,"7EE","2DCEAE",E
```
#### 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 Quectel modem to Monogoto 🎉**
{% endhint %}
## Test the connection by sending a UDP payload
A UDP payload test when the modem has an active data connection with a Satellite.
**Set and Active UDP Socket**
```
AT+QIACT=1
```
response:
```
OK
```
**Send UDP Payload** to the IP address `34.192.142.126`:
```
AT+QIOPEN=1,0,"UDP","34.192.142.126",12345
```
response:
```
OK
+QIOPEN: 0,0
```
**Send UDP Socket**
AT+QISEND=0,12
> HELLO WORLD
response:
```
SEND OK
+QIURC: "recv",0
```
**info UDP Socket**
```
AT+QIRD=0
```
response:
+QIRD: 12
HELLO WORLD
OK
\
**Close the UDP socket**
```
AT+QIDEACT=1
```
## 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 3 PINGs** to IP address `8.8.8.8`:
```
AT+QPING=1,"8.8.8.8",3
```
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
```
