The Waveshare 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.
Monogoto SIM
Raspberry Pi 2, 3, 4 or Zero
Insert the Monogoto SIM card at the bottom of the Waveshare HAT.
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:
Select: 3 Interface Options > P6 Serial Port
Answer <No> to “Would you like a login shell to be accessible over serial?”
Answer <YES> 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:
Connect with the modem via port ttyS0 using minicom:
Enter AT, if the modem responds with OK you successfully connected to the SIM7070G modem.
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
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:
Expected response: +APP PDP: 0,ACTIVE
Select the PDP index 0 for the PING test:
Expected response: OK
Send 5 PINGs to IP address 8.8.8.8 with a timeout of 20 seconds.
If the connection is active, you will see 5 PINGs with a number representing the response time in milliseconds. Example response:
Deactivate the PDP index after completing the PING test.
Expected response: +APP PDP: 0,DEACTIVE
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, is required.
Visit the documentation for a detailed guide on connecting the modem to Monogoto.
Great work on connecting the SIM7070G to Monogoto! Have a look at the Things logs in the to find more details about the established connection.
