3. Dailing up

NDIS Dail-up

  • Currently access to Windows 10 operating system use, connected to the 4G DONGLE module (equipped with mobile / telecom / Unicom 4G card), after installation of the driver, most of the current computers will automatically connect.
  • If Windows can not access the Internet, you need to manually start NDIS dial-up.
  • Download SIM7600 SSCOM.
  • Open SIM7600 AT port and send the command:
AT$QCRMCALL=1,1+Enter

Sim8200 win sendat1.png
At this point, NDIS dial-up takes effect and the computer is ready to connect to the network.
RNDIS Dail-up

  • Installed the SIM card and antenna, USB connected to the computer, and provide the power supply.
  • Refer to the above to install the USB driver.
  • Open the serial assistant, find the serial port number corresponding to AT serial port, and send:
AT+CPSI? //query if it is registered on the network
  • If you have successfully registered to the network, send another AT command to enable USB dial-up access:
at+Cusbpidswitch=9011,1,1
  • Sending is successful, return OK, and Dongle will reboot automatically.
  • Observe the device manager and find some unrecognized devices, such as RNDIS (with an exclamation mark):
  • Right-click RNDIS, search for the device software prompt window, and select "Browse My Computer". Select "Network Adapters" from the list of devices.
  • Select Microsoft Corporation from the list of manufacturers in the network adapter window, and then select "Remote NDIS Compatible Device" from the list on the right.

Click Next and wait for the installation to finish, the RNDIS Kitl device will be installed successfully. At this point, the dial-up function setup is complete and you can see that the PC can access the Internet through Dongle.

RNDIS dialing is not available on Win7 systems, please use the following command to change to (9001 mode) NDIS dialing: 
at+Cusbpidswitch=9001,1,1

PPP Dail-up

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

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

In theory, the uplink speed of a 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.

  • Now you can use a 4G network.
  • If you get a DNS error, please fix it with this command.
route add -net 0.0.0.0 wwan0

USB Voice Call

Due to the need to reduce size, the SIM7600G-H 4G Module does not come with built-in audio input-output interfaces in its design. However, the SIM7600 chip can input and output audio data in binary form through the Audio port in the USB port when using the voice call function. This example uses the audio output interface of the Raspberry Pi and the input function of a USB sound card to achieve real-time voice calls through data transmission via the USB port.
Hardware Preparation:

  • Raspberry Pi development board
  • SIM7600G-H 4G Module
  • USB Type-C cable
  • A SIM card capable of regular call services
  • An external sound card device with a microphone (a USB sound card is used in this example)

Hardware Connections:

  • Insert the SIM card into the SIM7600G-H 4G Module's card slot before powering it up.
  • Connect the SIM7600G-H 4G Module to the Raspberry Pi development board using the USB data cable.
  • Wait for the module to power on and connect to the communication network (as described in the previous section, 'NET LED Working Status').
  • Connect the sound card device to the Raspberry Pi.

Software Preparation: Enter the running command to confirm the status of the SIM7600G-H driver.

ls /dev/ttyUSB*

If it's the latest Raspberry Pi system, the system should come with the driver for this module. It should display five ports from ttyUSB0 to ttyUSB4, indicating that there's no need for additional installation.

Install python function library:

#pyaudio is the python module, installing pyaudio under Raspberry Pi, First you need to install portaudio.dev
sudo apt-get install portaudio.dev
#And then use
sudo apt-get install python-pyaudio
#Or
sudo apt-get install python3-pyaudio   #python3

Download demo and unzip.
Check the sound card driver status according to the selected sound card device (the USB sound card used in this example is a driverless sound card).
Querying the selected audio device number can be done with the pyaudio module: 

sudo python Audio_check.py

The program will list all available devices along with their corresponding numbers. Once you find the device based on its name, make a note of its corresponding number.

Test Process

As there are differences between the Raspberry Pi system and the audio device, it is recommended to modify the parameters before running the demo: 

stream_in=p.open(format=p.get_format_from_width(2),channels=1,rate=8000,input=True,input_device_index=1,stream_callback=pcm_out)
#This code initializes the audio input object, "input_device_index=1" indicates this object corresponds to the audio input device number, which may vary somewhat from device to device.

If there's an issue with the audio input, first check if the device is functioning properly. If the device is working correctly, the problem might be due to selecting the wrong device number. You can try the loopback test program below: 

sudo python Audio_test_R

This program will play audio data received from the audio input device on the audio output device. If there is no sound, you can try referring to the previously obtained list of audio devices. Modify the 'input_device_index' and 'output_device_index' parameters in the PyAudio initialization object statement. 

stream1=p.open(format=p.get_format_from_width(2), channels=1, rate=8000, input=True,input_device_index=1,stream_callback=pcm_in,frames_per_buffer=800)    #Parameter input_device_index
stream2=p.open(format=p.get_format_from_width(2), channels=1, rate=8000, output=True,output_device_index=0,stream_callback=pcm_out,frames_per_buffer=800)    #Parameter output_device_index

GNSS

GPS Positioning

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 the GPS antenna outside, and please test it on a sunny day. Power on and wait for several minutes to get the position;

2. AT Commands for GPS

  • Commands and test results:
AT+CGPS=1	    //Open GPS
AT+CGPSINFO       //Print GPS information to the serial port
AT+CGPS=0       //Close GPS

    Send SMS

Receive Message

  1. Send a message from the 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 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 (AT+CMGL="ALL" to read all messages)
  4. Delete message: AT+CMGD=20
  5. Convert the message to the string by convertor.
