How to Use

Dail-up

[Note]: You must use a SIM card with GPRS networking function enabled and not out of service.

NDIS Dail-up

At present, when using Windows 10 operating system, you can connect to 4G DONGLE module (equipped with 4G card of China Mobile/Telecom/Unicom). After installing the driver, most computers will automatically connect to the Internet.
If WINdows cannot access the Internet, you need to manually start NDIS dialing, open SIM7600 AT port, and send the command:

AT$QCRMCALL=1,1+enter

At this point, the NDIS dialing takes effect, and the computer can connect to the network; if the dialing command returns an error, send the following command to set the NDIS dialing mode and then dial again:

AT+CUSBPIDSWITCH=9001,1,1

RNDIS Dial-Up Internet

In addition, dial-up Internet access using RNDIS is also possible:

After the device installed SIM card and antenna, connect the USB port to computer, then connect the power supply.
Refer to the above to install the USB driver
Open the serial port assistant, find the serial port number corresponding to the AT serial port, and send the AT command to check whether it is registered on the network:

AT+CPSI?

If you have successfully registered on the network, then send the AT command to enable USB dial-up Internet access:

AT+CUSBPIDSWITCH=9011,1,1

If the transmission is successful, the DTU will return OK and reboot automatically.
And then you can find that there are some unrecognized devices in the Device Manager on the computer, such as RNDIS (with exclamation mark).

Right-click the 'RNDIS', search "Update Divers" and select "Let me pick from a list of available drivers on my computer", then select "Network adapters" from the device list.

Select "Microsoft" in the manufacturer list of the Network adapters window, and then select "Remote NDIS Compatible Device" in the list on the right, which is the remote NDIS compatible device.

Click 'Next' and wait for the installation to finish, the RNDIS Kitl device will be installed successfully. And then you can see that the PC can access the Internet via DTU.

PPP dial-up

If the NDIS or RNDIS dial-up cannot access the Internet, you can also use PPP dial-up. The operation steps are as follows：

Network and Internet Settings -> Set up a new connection -> Connect to the Internet -> Dial up (D) -> Dial a phone number (D): *99# (others are empty by default) -> Connection -> Register -> Connected to the Internet

GPS Test

GNSS control instance

Plug in the GPS antenna, and place the receiver tag face down in the open air, (Note that rainy weather cannot be tested) you need to wait about 1 minute before receiving the location signal.

Detailed test instructions and screenshots are as follows:

AT+CGPS=1               // Open GPS
AT+CGPSINFO             // Prints GPS information to the serial port
AT+CGPS=0               // Turn off GPS

TCP/IP Internet data

GPRS debugging requires a SIM card with the GPRS networking function enabled. The following example takes accessing a mobile SIM card as an example.

Correctly install the mobile phone card (the GPRS networking function must be enabled), the GSM antenna, and connect the USB cable to the computer;
Press the PWR key to start the module and wait for more than ten seconds;
Observe whether the indicator light is normal, the PWR indicator is always on, and the NET indicator is flashing;

Set up a local computer virtual server

The virtual server defines the mapping relationship between the WAN service port and the LAN network server. All accesses to the WAN service port will be relocated to the LAN network server specified by the IP address. (Please refer to your router's corresponding manufacturer's manual)

Use a browser to log in to the router management interface (please refer to your router manual for the specific address)
Set the port number: 2317 (it does not conflict with the existing port number. In this example, it is set to 2317)
Set the intranet IP of the computer (the IP obtained by the computer in the local area network can be run CMD on the local machine, enter the command line prompt, enter ipconfig to check the IPv4 address, the intranet IP of the computer in this example is 192.168.1.168), as shown in the following figure :

Configure GPRS

AT+CGDCONT=1,"IP","CMNET"     //Set APN
AT+CSQ       //Query the network signal quality. The first parameter is that the network signal quality is up to 31. The larger the value, the stronger the network signal.
AT+CREG?         //Query the network registration status, where the second parameter is 1, indicating that the registration has been successful.
AT+CIPMODE=1        //Set TCP/IP mode
AT+CSOCKSETPN=1          //select TCP/IP application mode
AT+CIPMODE=0          //select TCP/IP application mode
AT+NETOPEN         //startup mode 
AT+CIPOPEN=0,"TCP","113.81.233.65",2317         //Set TCP, IP and port number, establish TCP/IP connection 
AT+CIPSEND=0,9，         //To specify to send 9 characters of data, return to > to start sending 9 characters of content
AT+CIPCLOSE=0，         //close the TCP connection
AT+NETCLOSE，         //close the network

The operation is shown in the following figure:

Call Phone

Refer to the "Hardware Configuration" chapter to connect the LTE antenna, SIM card (the phone function must be enabled), and the headset cable with microphone, and the module is turned on.
Common commands for making calls:

AT+CNUM

Check the phone number (not all SIM cards support this command)

+CNUM OK

AT+CSDVC

AT+CSDVC=1: switch to headphone output AT+CSDVC=3: switch to speaker output

AT+CLVL=?

Answering the Phone

The detailed operation screenshots are as follows:

[Note]When using the SSCOM serial port assistant to send and receive AT commands, you must click "carriage return and line feed".

Voice output mode and volume adjustment

AT+CSDVC=1 		//switch to headphones 
AT+CSDVC =3 	        //switch to speaker
AT+CLVL =?		//Query the volume range, return +CLVL: (0-5) //Indicates that the volume is adjustable from 0 to 5
AT+CLVL=2     	        //Set the volume to 2, return OK

Answer the phone

Incoming call serial port display: RING
Send "ATA"      //Answer the phone
Send "AT+CHUP"  //Hang up

Audio parameter debugging

AT+CACDBFN=?
+CACDBFN: (Handset_cal.acdb,Handset_tianmai.acdb)	// It is recommended to consider setting this set of parameters 
OK

A.In the initialization stage of the module startup, before making a call, add the following

AT^PWRCTL=0,1,3	// Mainly improve TDD noise effect 
OK

B. The module is in the process of establishing a voice call

VOICE CALL:BEGIN  	// Establish module call to improve call    effect
AT+CECM=1      		//suppress echo
OK
AT+CECH=0x500 	// improve the volume on the mobile phone  
OK

See "SIM7X00_Audio_Application_Note" document for details.

AT+CMGS="phone number"<Enter>, set the recipient's phone number, and then return: ">", send the content that you need, such as "Send massage test!", You don’t need to “Enter” at the end. After editing the text message, send 1A to send information in hexadecimal format (1A is the key value of "CTRL+Z", which is used to tell the module to perform the sending operation, or 1B or "ESC" to cancel the operation). After successfully sending, the module returns + CMGS: 15 confirm that the transmission was successful. As shown below.

Receive English SMS

Send a message on the phone: "This is a receive test for SIM7600X!" to the test module.
When receiving the information, the serial port will break and report the information, "SM", 20, which means there are 20 pieces of information in the SM, and the message just sent is the 20th piece of information.
Read information: AT+CMGR=20 to read the 20th information (AT+CMGL="ALL" to read all information).
Delete information: AT+CMGD=20, as shown below.
Convert the displayed information to text through a code converter.
