Hardware connection

Attach the SIM7600G-H 4G for Jetson Nano (SIM7600 hereafter) on the 40PIN GPIO of Jetson Nano.
Inset the USB connector, and 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 the 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 install python3-pip
sudo pip3 install pyserial
mkdir -p ~/Documents/SIM7600X_4G_for_JETSON_NANO
wget -P ~/Documents/SIM7600X_4G_for_JETSON_NANO/ https://www.waveshare.com/w/upload/6/64/SIM7600X_4G_for_JETSON_NANO.tar.gz
cd ~/Documents/SIM7600X_4G_for_JETSON_NANO/
tar -xvf SIM7600X_4G_for_JETSON_NANO.tar.gz
sudo pip3 install Jetson.GPIO
sudo groupadd -f -r gpio
sudo usermod -a -G gpio your_user_name
sudo udevadm control --reload-rules && sudo udevadm trigger
sudo apt-get install minicom

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

Testing

Testing with minicom

Before you test the SIM7600, you need to install 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 a response, please check if you have set the DIP switch to 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 in an 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 the vi tools 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 su
killall ModemManager 
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 unzip Simcom_wwan.zip 
cd simcom_wwan 
sudo su 
make

Use root permission to install driver

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
