Hardware Connection

• Prepare：
  
  • SIM7600X 4G DONGLE
  • A 4G Nano SIM card（The card should be workable and 4G accessible）
• Assemble the 4G antenna;
• Open the SIM card buckle, pull the SIM card slot according to the arrow as below;

• Plug the 4G SIM card and LOCK the SIM card slot according to the arrow, then close the buckle.
• Connect the USB port of the DONGLE to your PC. Raspberry Pi or other devices
  
• If you want to use GPS, please make sure that the DONGLE you bought is the SIM7600G-H version. You should set the receiver on the outside for GPS testing.

4G Connecting

Networking in Windows PC

1、Hardware Connection

2、Driver Installation

• Download the driver：SIM7600X Driver
• Connect the DONGLE to Windows PC (Hereafter we use Windows 10 PC as example)）
• Open Device Manager—>Other Devices—>“SimTech, Incorporated”—>Update driver—>Browse my compute for driver software—>Choose the driver according to your OS—>Install it
  

• After installation, all the devices should be recognized normally as below:

3、Dailing up

• Connect the 4G DONGLEto Windows 10 PC， install drivers as the guide above.Then most of the PC will auto-connect to 4G network.
  

If your PC cannot auto-connect, you can try with PPPoE method:
 
     

In theory, the uplink speed of 4G network is up to 150Mbps and the downlink speed is up to 50Mpbs.
However, the actual speed is influenced by the Network coverage rate, time, network situation and the base station, etc.
Therefore, the actual speed of the 4G network will be slower than the expected data. In this case, you can change the area test it again or try it at other times.

Setup 4G Connection for Raspberry Pi (Raspbian)

1、Hardware connection

2、Setting

The driver of SIM7600X has been pre-installed in Raspberry Pi OS (Raspbian), you need to install it again. You can following the following guide to set up 4G network connection. There are three ways:

• Raspberry Pi networked via RNDIS ——（Simplest）
  
• SIM868 PPP Dail-up Networking ——（Simple）
  
• Setup wwan0 interface for 4G network （Related code） ——（Complicated）
  

Set up Network for Jetson Nano

1、Hardware connection

2、Setting

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

GNSS

GPS Positing

1、Hardware connection

• Note：SIM7600CE-CNSE 4G DONGLE doesn't feature GPS function. If you want to use GPS, please purchase SIM7600G-H 4G DONGLE and GPS antenna separately.
• Remove the case, assemble the GPS antenna and replace it and close.
  
  
• When testing,You should set the receiver of GPS antenna in outside and please test it in sunny day., Power on and waiting for several minuts to get the postion;
  

2、AT Commands for GPS

• Commands and test result：

AT+CGPS=1	    //Open GPS
AT+CGPSINFO       //Print GPS information to serial port
AT+CGPS=0       //Close GPS

3、Obtain GPS data by software

Send SMS

1. Assemble SIM card, LTE antenna。 Connect DONGLE to PC and power on it;
2. Check if the indicators work normally, PWR keep lighting and NET is blinking;
3. Set local SMS center: AT+CSCA="+8613800755500"+ ENTER，It will response OK。
   Note: the number of SMS center is different among different areas, please confirm your local SMS center and modify it;
4. AT+CMGS="phone number"<ENTEER>, Set the target phone number, it will response:“>”, input the content and send, for example:“Send massage test!”, Add 1A in hex in the end of the content to confirm the SMS content and send it without ENTER (You can also send 1B in hex to cancel the sending), Module response +CMGS：15 if SNS is sent properly
   

Send SMS

1. end a message from phone to the SIM7600 DONGLE: “This is a receive test for SIM7600X！”
2. The serial port will print data when receiving, for example: “SM”， 20， it means that there are 20 messages in SM and the last message received is the 20th message.
3. Read message：AT+CMGR=20 Read the 20th message读（AT+CMGL="ALL" to read all messages）
4. Delete message：AT+CMGD=20
5. Convert the message to string by convertor.。
