Hardware connection

  • Attach the SIM7600G-H 4G for Jetson Nano (SIM7600 hereafter) on 40PIN GPIO of Jetson Nano.
  • Inset the USB connector, connect the micro USB interface of SIM7600 to Jetson Nano
    • If you want to communicate SIM7600 via Serial port, you can also turn the DIP switcher into ON
  • Connect MAIN antenna and the GPS antenna

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

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
