The CELLv1.0 is an easy-to-use cellular development kit. Add it to your Arduino, Raspberry Pi, or any other project you have to instantly add wireless communications capable of operating anywhere in the world!
Purchase the kit through RS Components. It includes the SparqEE CELL, a wall power supply, usb cable, antenna, and a SparqSIM – everything you need to get your device on the internet!
Check out the Arduino and Raspberry Pi Shields to see just how easy it is to connect the CELLv1.0 to your Arduino and Raspberry Pi!
If you’re not using a shield, all you need are 4 connections – RX, TX, GND, and Vref so you can use your 3.3V or 5V system. Use the USB cable we supply for power and voilà!
SparqEE helps you every step of the way with the CELLv1.0 to easily get your data from Your Device, through The Cloud, and back out to Your Smartphone or Computer!
In order to communicate over a cellular network, you’ll also need a SIM card. SIM cards aren’t as painful as they used to be. With the CELLv1.0 you can use any SIM, here are some suggestions:
Just power the CELLv1.0 from the USB and that’s it. Use with the RasPi code we supply.
Just power the CELLv1.0 from the USB and that’s it. Use with the Arduino code we supply.
View the “Code & Examples” section below. It provides sets of code to complete various tasks such as sending a text (SMS) and sending data to a server.
Drivers are provided to connect to the cellular module over the USB connection. The typical usage is to connect to the SparqEE CELL via the UART using a Raspberry Pi, Arduino, Level Shifter, or any UART operating at 115200bps.
The CELLv1.0 must be turned on in order to use it.
Two ways to turn it on:
If it’s on, one of the three main LEDs will be lit.

Same steps as the Raspberry Pi except the script is going to be something like the following. You may have to change some parameters as noted:
sudo ./sakis3g connect --nostorage --pppd APN="Internetd.gdsp" APN_USER="user" APN_PASS="pass" USBINTERFACE="1" USBDRIVER="option" OTHER="USBMODEM" USBMODEM="19d2:0117" OPTION NOTE APN Should be the APN from your particular provider (typically on the SIM card package) APN_USER Same as APN, but for username. If none, leave as-is APN_PASS Same as APN, but for password. If none, leave as-is USBINTERFACE The 'X' digit(s) following the USB modem from /dev/ttyUSBX USBMODEM USB Modem MAC addr from "lsusb" (when the modem is on), ex: 19d2:0117 If everything goes well, you should be presented with something like: "MF206A connected to DATA ONLY (310410)." This means it's connected!!!
View all information we have on Sakis3g on the Raspberry Pi Page
Using minicom, see what the SIM card reports for the command at+cgdcont=? With the SparqSIM SIM card, it should include "Internetd.gdsp" and look something like this: +CGDCONT: 1,"IP","Internetd.gdsp","0.0.0.0",0,0 If the APN isn't correct, then enter the following and try again: at+cgdcont=1,"IP","Internetd.gdsp"
