PPP installer for Sixfab Shield/HAT

Sixfab offers Shields/HATs for Raspberry Pi which provides cellular PPP Internet connection anywhere with the availability of mobile network coverage. These shields are:

This Tutorial is maintained in our documentation section.

Base Shield
Base HAT
Cellular App. IoT Shield
Cellular IoT HAT
Tracker HAT

Please submit your technical issues and feedback to the community forum.

Each of these shields can be connected to the Internet via PPP(Point to Point Protocol). For this tutorial, we have written a script to install and perform the required steps.

Without further ado let us jump into the installation process:

1. Get the script by the following command

wget https://raw.githubusercontent.com/sixfab/Sixfab_PPP_Installer/master/ppp_installer/install.sh

2. Now change the permission of the downloaded script. chmod +x install.sh

3. Now install the script sudo ./install.sh It will ask several questions, just answer them accordingly to complete the installation process. The questions are:

  • Please choose your Sixfab Shields/HATs
    You will be offered to choose among the mentioned three shields. Then it will fetch required scripts for you.
  • Do you have updated kernel
    It asks if your kernel is up-to-date. If no[N] it updates the kernel else it skips the update. Then it installs ppp.
  • What is your carrier APN?
    Here, it asks for your carrier’s APN. For me it is hologram.
  • Enter your PORT name
    In this step you will enter your PORT. For 3G, 4G/LTE Base Shield && Base HAT it will be ttyUSB3.
  • Do you want to activate auto-connect/reconnect service at R.Pi boot up?
    This option allows you to connect to the Internet via your shield automatically when your Raspberry Pi Starts. If you want to connect to the Internet automatically type y else N. If you have selected N then you will need to run sudo pon to connect to the internet and sudo poff to stop it. Make sure your module is powered up(Not applicable for Base Shield).












Enjoy your Internet connection.


Route: One of the possible errors you may get is the routing error. In this case, run the following commands

sudo route del default
sudo route add default ppp0

If your carrier asks for username and password;
Remove noauth  from /etc/ppp/peers/provider  and add following lines


Selecting port

GSM/GPRS Shield ttyS0/ttyUSB0
Base Shield / Base HAT ttyUSB3
Cellular IoT App. Shield / Cellular IoT HAT ttyS0/ttyUSB3
Tracker HAT ttyS0

To understand PPP further you can check PPP documentation.

Sensor Test Tutorial for Sixfab Arduino Cellular IoT Application Shield

Sixfab has came up with Arduino Cellular IoT shield that have combined LTE technilogies Cat.M1, Cat.NB1(NB-IoT) and eGPRS, which is based on Quectel BG96 module. It also have built-it sensors, LED and relay. Sixfab also has a RPi Cellular IoT Application HAT.

Sixfab is also providing library to use the shield. To keep the it easy we will be showing how to install the library and access the sensor data in our first tutorial.  Read More

Measuring Lux with Sixfab Arduino NB-IoT Shield

We are back again with another tutorial on Sixfab Arduino NB-IoT Shield. Previously we have learned how to connect the shield with local server and sent a string value. In this tutorial we are going to learn how we can access the sensor values of the built-in sensors of the shield and send them over local server. To keep it easy we are going to access single sensor which will be ambient light sensor(ALS-PT19). Read More

Getting Started with SIXFAB Arduino NB-IoT Shield

Sixfab Arduino NB-IoT shield is a Narrow-Band IoT(LTE CAT-NB1) shield for Arduino, based on Quectel’s BC95 module. NB-IoT is a Low Power Wide Area(LPWA) technology that is the latest cellular network option for low power connected projects.

This shield has been designed with built-in temperature, humidity, light sensors, 3-axis accelerometer, relay, micro sim card slot and a built-in antenna. If there is a need for long-range, better signal quality, a U.FL antenna receptacle is placed, can be selected over RF Switch by the short-headers easily. Read More
