4G/5G Module Compatibility
If you need to use the M.2 TO 4G/5G HAT for other 4G/5G modules, you can refer to the M.2 connection diagram below, check whether there is any pin conflict, and then connect to test:
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 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:
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:
If you have successfully registered on the network, then send the AT command to enable USB dial-up Internet access:
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:
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
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
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:
[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
Answer the phone
Audio parameter debugging
A.In the initialization stage of the module startup, before making a call, add the following
B. The module is in the process of establishing a voice call
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
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.
