Software setup

• Open a terminal and install libraries by the following commands

sudo apt-get update
sudo apt-get python3-pip
sudo pip3 install pyserial
sudo apt-get install p7zip

• Download demo codes

mkdir -p ~/Documents/SIM7600X_4G_for_JETSON_NANO
wget -P ~/Documents/SIM7600X_4G_for_JETSON_NANO/ https://www.waveshare.com/wiki/File:SIM7600X_4G_for_JETSON_NANO.7z
cd ~/Documents/SIM7600X_4G_for_JETSON_NANO/
sudo p7zip --uncompress SIM7600X_4G_for_JETSON_NANO.7z
sudo pip3 install Jetson.GPIO
sudo groupadd -f -r gpio
sudo usermod -a -G gpio your_user_name
sudo apt-get install minicom -y

Note: you should replace your_user_name with the actual user name.

Testing

Testing with minicom

Before you test the SIM7600, you need to intail it with the following commands

echo 200 > /sys/class/gpio/export
echo out > /sys/class/gpio200/direction
echo 1 > /sys/class/gpio200/value
echo 0 > /sys/class/gpio200/value

Make sure that the NET is blinking normally.

Run minicom and type AT commands to test

sudo minicom -D /dev/ttyTHS1 -b 115200

If you cannot get response, please check if you have set the DIP switch into ON

Python examples

• Make sure that all the hardware are connected properly. Start Jetson Nano and open a terminal
• AT examples
  • You should run the following commands to run the codes and type AT commands for testing

cd ~/Documents/SIM7600X_4G_for_JETSON_NANO/AT/
sudo python3 AT.py

• GPS examples
  • Connect the GPS antenna and set the receiver at open place.
  • You should run the following commands to run the codes to test GPS.

cd ~/Documents/SIM7600X_4G_for_JETSON_NANO/GPS/
sudo python3 GPS.py

• PhoneCall examples
  • Modify the PhoneCall.py file, change the phone number to yours by vi tool and save
  • Finally use the following command to run the code

cd ~/Documents/SIM7600X_4G_for_JETSON_NANO/PhoneCall/
vi PhoneCall.py #modify the phone number
sudo python3 PhoneCall.py

• SMS example
  • Run the following commands

cd ~/Documents/SIM7600X_4G_for_JETSON_NANO/SMS/
sudo python3 SMS.py

• TCP example
  • Run the following commands

cd ~/Documents/SIM7600X_4G_for_JETSON_NANO/TCP/
sudo python3 TCP.py

4G connecting

Please connect all the hardware and start Jetson Nano.

• Check and make sure that the module work normally by demo codes above.
• Open minicom by command

sudo minicom -D /dev/ttyUSB2

• Type the following command to check

AT+CNMP=38
AT+CSQ
AT+CREG?
AT+COPS?
AT+CPSI?

• Download driver

cd
wget https://www.waveshare.com/w/upload/4/46/Simcom_wwan.zip
tar zxvf Simcom_wwan.zip
cd Simcom_wwan
sudo make

• Use root permission to install driver

sudo su
insmod simcom_wwan.ko
lsmod
dmesg

• Check if the wwan0 interface is recognized

ifconfig -a

• Enable the wwan0 interface

ifconfig wwan0 up

• Dailing by minicom

minicom -D /dev/ttyUSB2
AT$QCRMCALL=1,1

• Allocate IP

apt-get install udhcpc
udhcpc -i wwan0

• Now you can use 4G network
• If you get dns error, please fix it by this command

route add -net 0.0.0.0 wwan0
