# Waveshare SIM7070G
The Waveshare [SIM7070G](https://www.simcom.com/product/SIM7070G.html) HAT for Raspberry Pi has global support for LTE Cat-M1, NB-IoT, GPRS and EDGE, as well as GNSS positioning. It can be easily attached to the 40 GPIO pins of the Raspberry Pi as well as to microcontrollers such as the Arduino or STM32.

### Prerequisites
* Monogoto SIM
* [Waveshare SIM7070G HAT](https://www.waveshare.com/sim7070g-cat-m-nb-iot-gprs-hat.htm)
* Raspberry Pi 2, 3, 4 or Zero
## Getting Started with the Waveshare SIM7070G
Insert the **Monogoto SIM card** at the bottom of the Waveshare HAT.
{% hint style="info" %}
This guide explains how to connect the Waveshare HAT to the Raspberry Pit. It is also possible to **connect your Windows, MaxOS or Linux machine to the Waveshare HAT directly** allowing you to configure the SIM7070G modem without the need for a Raspberry Pi.
To do so, connect your computer to the micro USB port of the Waveshsare HAT and connect to the modem using PuTTY (Windows), minicom, screen or miniterm (Linux/MacOS). When using Windows, [**this driver**](https://www.waveshare.com/w/upload/2/2f/SIM7070_SIM7080_WIN7_WIN10_USB_Driver_V1.00.rar) is required.
{% endhint %}
Connect the **LTE** and **GNSS antennas** and add the Waveshare HAT to a Raspberry Pi using the 40 GPIO pins.
Power the Raspberry Pi and connect to it using SSH, or by connecting a keyboard and mouse.
Click and hold the **PWRKEY** for about 1 second, until the **NET** LED starts blinking **red**.
Enable the **hardware serial**, allowing the Raspberry Pi to communicate with the Waveshare HAT. To do so, open the **Raspberry Pi Software Configuration Tool** by entering the following command in your terminal:
```bash
sudo raspi-config
```
Select: **3 Interface Options** > **P6 Serial Port**
 
Answer **\** to “Would you like a login shell to be accessible over serial?”
Answer **\** to “Would you like the serial port hardware to be enabled?”
 
Install **minicom** to be used as the tool to interface with the SIM7070G modem:
```bash
sudo apt-get install minicom
```
{% hint style="info" %}
Alternatives to **minicom** for Linux or MacOS are **miniterm** or **screen**, feel free to use your application of choice. When using Windows to connect to the Raspberry Pi, you can use **PuTTY**
{% endhint %}
**Connect with the modem** via port `ttyS0` using minicom:
```
minicom -D /dev/ttyS0
```
Enter `AT`, if the modem responds with `OK` you successfully connected to the SIM7070G modem.
{% hint style="warning" %}
In case you don’t manage to open the ttyS0 connection or don't receive an `OK`:
* Try rebooting the Raspberry Pi and try again
* Double check if the **NET** LED is blinking **red**. If not, click and hold the **PWRKEY** button for 1 second
* Be patient, it may take some time before the modem responds
{% endhint %}
## Connect the SIM7070G to Monogoto
Visit the [SIMCom SIM7070G](/getting-started/general-device-configurations/iot-devices/simcom-sim7070g.md) documentation for a detailed guide on connecting the modem to Monogoto.

## 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.
**Activate a data connection** for PDP index `0`**:**
```
AT+CNACT=0,1
```
Expected response: `+APP PDP: 0,ACTIVE`
**Select the PDP index** `0` for the PING test:
```
AT+SNPDPID=0
```
Expected response: `OK`
**Send 5 PINGs** to IP address `8.8.8.8` with a timeout of 20 seconds.
```
AT+SNPING4="8.8.8.8",5,1,20000
```
If the connection is active, you will see 5 PINGs with a number representing the response time in milliseconds. Example response:
```
+SNPING4: 1,8.8.8.8,104
+SNPING4: 2,8.8.8.8,93
+SNPING4: 3,8.8.8.8,145
+SNPING4: 4,8.8.8.8,75
+SNPING4: 5,8.8.8.8,157
```
**Deactivate the PDP index** after completing the PING test.
```
AT+CNACT=0,0
```
Expected response: `+APP PDP: 0,DEACTIVE`
{% hint style="success" %}
**Great work on connecting the SIM7070G 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.
