Once you have built your Yattaphone<\/a>, you need to connect it to the internet and have a software that lets you make phone calls.<\/p>\n\n\n\n

The connection script<\/h3>\n\n\n\n

Prior to running the script that you can find hereafter, you need to install some packages (in order to do that, connect the Raspberry to internet using WiFi<\/a> or an Ethernet<\/a> cable).<\/p>\n\n\n\n

sudo apt-get update && sudo apt-get install libqmi-utils udhcpc<\/p>\n\n\n\n

Next, you can insert in the 4G Board a SIM and connect to the internet through the following script:<\/p>\n\n\n\n

!\/bin\/bash
sudo qmicli -d \/dev\/cdc-wdm0 –dms-set-operating-mode=’online’

#Check the signal
<\/em>sudo qmicli -d \/dev\/cdc-wdm0 –dms-get-operating-mode
sudo qmicli -d \/dev\/cdc-wdm0 –nas-get-signal-strength
sudo qmicli -d \/dev\/cdc-wdm0 –nas-get-home-network

#Reconfigure the network interface for raw-ip protocol
<\/em>sudo qmicli -d \/dev\/cdc-wdm0 -w
#this confirms the name of the network interface, typically wwan0
<\/em>sudo ip link set wwan0 down
#change the wwan0 to the one returned above if different
<\/em>
echo ‘Y’ | sudo tee \/sys\/class\/net\/wwan0\/qmi\/raw_ip
sudo ip link set wwan0 up

#NOTE: replace “wap.tim.it” with the APN of your own SIM network and PASSWORD with your own password
<\/strong>sudo qmicli -p -d \/dev\/cdc-wdm0 –device-open-net=’net-raw-ip|net-no-qos-header’ –wds-start-network=”apn=’wap.tim.it’,username=’pi’,password=’PASSWORD,ip-type=4″ –client-no-release-cid

#configure the IP address and the default route with udhcpc
sudo udhcpc -i wwan0
ip a s wwan0
sleep 2
ip r s<\/p>\n\n\n\n

If you wish, you can download this script<\/a> here.<\/h6>\n\n\n\n

Note: sometimes it does not immediately work and you have to run it several times before it actually gets your Raspberry on the internet.
<\/p>\n\n\n\n

The phone calls interface<\/h3>\n\n\n\n

Next, you need an interface to make the calls. Here it is:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
You can download it<\/a> here.<\/h6>\n\n\n\n

It is a Python 3 script.
Note: in order to run it, you need to install all the needed Python 3 modules: threading<\/strong>, time<\/strong>, tkinter<\/strong>, RPi.GPIO<\/strong>, serial<\/strong> and pygame<\/strong>.<\/p>\n\n\n\n

Then you can run the script:<\/p>\n\n\n\n

python3 yattaphone.py<\/p>\n\n\n\n

The C<\/strong> button C<\/strong>alls.<\/p>\n\n\n\n

The A<\/strong> button A<\/strong>nswers.<\/p>\n\n\n\n

The O<\/strong> button hangs up.<\/p>\n\n\n\n

The SMS<\/strong> button shows all the SMSs stored in the SIM memory.<\/p>\n\n\n\n

The M<\/strong> button is for debug, it reads the serial. If everything works, you don’t need it, as the serial is checked (and its content displayed) once a second. Each time a point is printed out.
Note: if you do not see a new point in line every second, it means that it is not working and it is not checking the serial<\/strong>.<\/p>\n\n\n\n
