... ....
OK

AT command sending and receiving test

  1. Download serial debugging assistant: SIM7600 serial debugging assistant
  2. Open the device manager, find the port number corresponding to AT Port; then open the sscom software, select the corresponding port and baud rate, check "Add carriage return and line feed"; click the sscom "Extension" button and pull out the preset It is best to open the serial port and send the corresponding AT command to test. The test screenshot is shown below:

Dailing up

PC Windows

  • Usually, when we use the Windows 10 operating system, make sure that the hardware and software drivers are installed. After the module is powered on, the PWR light is on normally, the NET light is flashing normally, and it will automatically connect to the Internet. If the Internet cannot be automatically connected, we can also use NDIS or PPPD to connect to the Internet.

NDIS

The steps for Windows NDIS dialing are as follows:
1. Open the SIM7600 AT port, and send the command (if using SSCOM to generate AT command, you must check "Enter"):

AT$QCRMCALL=1,1 //must press "Enter"

Enter.png
2. At this point, the NDIS dialing takes effect, and the computer can connect to the network.

RNDIS Dial Up

Remote NDIS (RNDIS) allows writing NDIS miniport device drivers for network devices attached to the USB bus without the need for hardware vendors. RNDIS achieves this by defining a bus-independent set of messages and describing how this message set operates over the USB bus. As this remote NDIS interface is standardized, a set of host drivers can support any number of network devices attached to the USB bus. This significantly reduces the development burden for device manufacturers, enhances overall system stability by eliminating the need for new drivers, and improves the end-user experience.

  • Install the SIM card and the antenna on the device, connect the USB cable to the PC, and provide the power supply.
  • Install USB driver.
  • Open the serial port assistant, find the corresponding COM port to the AT serial port, and send:
AT+CPSI? //Query whether to register the network
  • If the network is registered successfully, SIM7600X can send the AT command to enable USB dial-up:
at+Cusbpidswitch=9011,1,1
  • SIM820X sends AT commands to enable the USB dial-up:
at+cusbcfg=usbid,1e0e,9011
  • Successfully sent, and received as 'OK,' and the Dongle will automatically reboot.
  • Observing the Device Manager, it's noticed that some unrecognized devices have appeared, such as RNDIS (with an exclamation mark):
  • Right-click on RNDIS, go to the device software search window, and choose 'Browse my computer.' Select 'Network Adapter' from the device list.
  • In the network adapter window, choose Microsoft Corporation from the manufacturer list, then select 'Remote NDIS Compatible Device' from the list on the right-hand side.
  • Click 'Next' and wait for the installation to finish; the RNDIS Kitl device will be successfully installed. With this, the dial-up function setup is complete, and it can be seen that the PC can access the internet through the Dongle.

GNSS Control Example

  • Connect the GPS antenna and place the receiver with the label facing downwards in an open outdoor area (note: testing cannot be done during rainy weather). It takes about 1 minute after powering on to receive a positioning signal.
  • Detailed testing instructions and screenshots are provided below:
AT+CGPS=1	  //Open GPS
AT+CGPSINFO      //Print GPS message to the serial port 
AT+CGPS=0       //Turn off GPS

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
OK
AT+CLVL=? Query volume range OK
AT+CLVL=2 set volume to 2 OK
ATD<phone_number>; ATD10086; Dial Mobile customer service phone number 10086 OK
AT+CHUP set volume to 2 OK
AT+CLIP=1 Set up caller ID OK
ATA Answering the Phone OK
  • The detailed operation screenshots are as follows:

Gprs2.png
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 content:

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.

Send English SMS

1. Correctly install the SIM card and LTE antenna, connect the module's USB interface to the computer with a USB cable, and turn on the module;
2. Observe whether the indicator light is normal, the PWR indicator is always on, and the NET indicator is flashing;
3. Set the local SMS center: AT + CSCA = " + 8613800755500" + Enter, return OK.

Note: China Mobile's SMS service center number is +861380xxxx500, where xxxx is the long-distance telephone area code where you are located. The SMS center may be different from place to place. For details, you can query Baidu or call China Mobile Unicom customer service. This SMS center is Shenzhen (0755).

4. AT+CMGF=1: Set the SMS mode to TEXT;
5. 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

  1. Send a message on the phone: "This is a receive test for SIM7600X!" to the test module.
  2. 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.
  3. Read information: AT+CMGR=20 to read the 20th information (AT+CMGL="ALL" to read all information).
