* FLIGHTMODE is wired to pull up and will enter into flight mode.

Raspberry Pi initialization settings

To ensure that the SIM7600X 4G HAT can work normally after being connected to the Raspberry Pi, it is necessary to initialize the level output of some pins of the Raspberry Pi. The specific operations are as follows:

• Download sample demo, after decompression, rename the c folder under the Raspberry folder to SIM7600X, Then copy the entire SIM7600X folder to the Raspberry Pi /home/pi directory.
• The command line enters the /home/pi/SIM7600X directory and executes the command.

chmod 777 sim7600_4G_hat_init

• Set the boot initialization script, and run the command:

sudo nano /etc/rc.local

• Add before exit 0 (as shown below):

sh /home/pi/SIM7600X/sim7600_4G_hat_init

Raspberry Pi serial port configuration

Since the Raspberry Pi serial port is used for terminal debugging by default, if you need to use the serial port, you need to modify the Raspberry Pi settings. Execute the following command to enter the Raspberry Pi configuration:

sudo raspi-config

Select Interfacing Options -> Serial -> no -> yes to disable serial debugging. Open the /boot/config.txt file, and find the following configuration statement to enable the serial port, if not, add it at the end of the file:

enable_uart=1

Restart to take effect.

Raspberry Pi minicom serial port debugging

1. Insert the module into the Raspberry Pi. 2. Install minicom, which is a serial debugging tool for the Linux platform:

sudo apt-get install minicom

3. Execute minicom -D /dev/ttyS0 (ttyS0 is the serial port of Raspberry Pi 3B/3B+/4B). The default baud rate is 115200. Raspberry Pi 5/2B/zero, the user serial device number is ttyAMA0, and the Raspberry Pi 3B/3B+/4B serial device number is ttyS0. 4. Take the AT synchronization test as an example, and send relevant commands, as shown in the following figure: * minicom can enter setting mode by pressing Ctrl+A, then Z, and select X to exit. 5. Raspberry Pi 5 configures the ttyS0 serial port:

• Edit config.txt file:

 sudo nano /boot/config.txt

• Add the following and the statement at the end.

 dtoverlay=disable-bt

• You can see ttyS0 after restarting.

What is the role of the AUX antenna, can not connect the MAIN antenna, only connect the AUX antenna?

1. The AUX auxiliary antenna is a diversity antenna, the main antenna signal is not good enough to receive the signal with the receiving antenna, and the physical location is not the same, there is always a better, diversity antenna connected to the bandwidth and rate sensitivity will be increased by about 20%.

2. No diversity antenna can make the receiver obtain a maximum of not more than 3db diversity gain, but the diversity does not line any transmitting function, so to connect to the main antenna, transmit the signal to the base station registered to the network, the auxiliary antenna will only work.

How to debug SIM7600X via USB TO UART serial port?

Please put the jumper cap on C and connect the USB TO UART interface of SIM7600X to the USB port of a computer or Linux board such as Raspberry Pi through USB type to micro USB to send commands to debug:

What is the working current when connected to the Internet?

Using a USB 5V power supply, after successful networking, the current is generally in the range of 50~300mA, and the average is about 150mA (for reference only, depending on the network environment and networking status.

Why can I access the Internet with a regular cell phone SIM card that can make phone calls, but not with an IoT card (traffic card)?

• Confirm whether the frequency band supported by the IoT card covers the frequency band supported by the module.

• APN is not set, please use the following command to configure APN.

• Note: Different operators' APNs is different, here the APN is changed to the corresponding operator.

• It may be blocked, high traffic (real-name IoT) cards are going to be machine card binding, and can only be used on a device (the State Ministry of Industry and Information Technology, Ministry of Public Security, issued to the operator must be so); you can let the IoT card operator check the status of the card and unlock the next.

When sending AT+CPIN?, return ERROR

This problem is generally caused by poor contact between the SIM card and the SIM card holder of the module.

What's the type of SIM card ?

Support SIM standard (Standard) card, as shown in the figure below, if it is a Micro or Nano card, you need to add a card sleeve.

SIM7600X SMS transmission failure, prompt +CMS ERROR? or CME ERROR and other errors?

• Confirming that the SIM7600X is registered to the network and that the SIM card can send and receive SMS messages properly on devices such as cell phones;

• Setting the correct SMS center number;

• Initialize the SMS settings with the following command:

AT+CSCS="IRA"
AT+CSMP=17,167,

How to set up SMS center number? (SMS center number is a kind of short message server. The SMS messages sent by cell phones need to be sent to the SMS center number first, and then forwarded to the other phone by the SMS center number, which is equivalent to an SMS relay station.)

AT+CSCA="[phone]"

The command should be added + enter to return OK.

How many SMS messages can the SIM7600CE 4G HAT save?

If the short message is stored in the SIM card, the limit is generally 50. You can use the command: AT+CPMS? make an inquiry.

The command for SIM7600Xcall recording and playback is?

SIM7600X makes a call and the phone answers
ATD131xxxxx816.

Record SIM7600 and phone sound to module memory E disk (record to memory card read D)
AT+CREC=3, "e:/rec.wav"   

End recording
AT+CREC=0

Play sound to the phone side to listen
AT+CCMXPLAYWAV="E:/rec.wav",1

Play sound to SIM7600
AT+CCMXPLAYWAV="E:/rec.wav",2

End playback
AT+CCMXSTOP

Some SIM card carriers require a VOLTE function to make calls, how to turn on or off the VOLTE function?

The VOLTE function can be enabled with the following command:

at+voltesetting=1
at+cnv=/nv/item_files/modem/mmode/ue_usage_setting,1,01,1

The VOLTE function can be disabled with the following command:

at+voltesetting=0
at+cnv=/nv/item_files/modem/mmode/ue_usage_setting,0,01,1

Note: The difference between Volte calls and regular phone calls: The network of Microsoft calls goes on a packet-switched Internet network. And ordinary phone calls take the circuit-switched (PSTN network) communication network. There is a fundamental difference between the two. By the time of 4G LTE, the packet network can control the delay to low enough, and ordinary phones can make calls directly through VOLTE with the packet network. However, in places where the network is poor, circuit-switched networks are still inseparable.

How to locate the base station for SIM7600X, what is the command?

Common commands for the LBS base station positioning function of SIM7600X are as follows:

AT+CLBS=? //View the range of parameters that can be set
AT+CNETSTART//Open the network; if it fails to open the network, you can use the command AT+CNETSTOP to close and then open
AT+CLBS=1 //Get the current latitude and longitude
AT+CLBS=2 //Get the detailed address

Why is the positioning inaccurate and the coordinates obtained are different from those found online?

After turning on the GPS in the AT debug serial port, turn on the NMEA port to get the dynamic information.

For more detailed steps, please refer to the following link. SIM7600X gets the latitude and longitude in units, we commonly use degrees as the unit, please see below for more details.

• SIM7600X Positioning_via_uSTAR
• SIM7600G-H_4G_for_Jetson_Nano_Precisely_Locates_in_Gaode_Map_API
• SIMXXX_Locates_My_Location_on_Gaode_Map

AT PORT does not get the location information, HS-USB NMEA port can get it, what is the problem?

GNSS parameter problem, after restarting the module, initialize the GNSS parameters with the following command can be;

AT+CGPSNMEA=197119

Or you can use the following commands to obtain the position information.

AT+CGPSINFOCFG=10,31

What should I do if I can't receive a GPS signal and don't get the location information?

Insert the GPS antenna into the GNSS antenna holder and place the receiver label side down in the open outdoors (note that the rainy weather test can not), the power needs to wait about 1 minute to receive the positioning signal;

What does the positioning information obtained by SIM7600X via AT+CGPSINFO represent respectively?

From left to right, they are (1) dimension, (2) longitude, (3) date, (4) time, (5) altitude, (6) speed, and (7) heading angle.

Why is my dial-up internet connection so slow?

• Generally, the default configuration of SIM7600 is to automatically select the network standard, and it is likely to choose 2G Internet access; if you need to force the use of 4G mode, you need to enter the following AT command configuration:

AT+CNMP=38    //Fixed 4G LTE, if there is no local 4G coverage, you may not be able to register to the network

• If 4G has been fixed and the speed is still not ideal, it may be a frequency band problem;

AT+CNBP?  //Backup the current band (the returned band information can be copied to Notepad, etc.)

AT+CNBP=0x0002000000400183,0x000001E000000000,0x0000000000000021    //After returning to OK, measure the speed

AT+CNBP=0x0002000004400180,0x000001E000000000,0x000000000000003F   //If the speed doesn't improve, try this

Why does it return NO CARRIER after the computer NDIS dials?

AT$QCRMCALL=1,1

Answer:

• Under normal circumstances, SIM7600X has already dialed automatically when it is connected to the Windows system, no need to repeat the dialing, the repeated dialing will return NO CARRIER

• If you still cannot dial up, please use the following command to change to the Windows default dial-up mode

  AT+CUSBPIDSWITCH=9001,1,1 

• The display is turned off and the mobile network is not enabled, you can ignore it and go online directly;

• You can also install the driver SIM7600X dial-up Driver to update the network card

• After installing the driver, the network card shows that it is enabled

How to get SIM7600X to switch to IPV6 after dial-up?

Set up as below:

AT+CGDCONT=1, "IPV6", "APN" //Switch to IPV6, different operators APN is different, pay attention to distinguish the settings
AT+CGDCONT=1, "IP", "APN" //Switch back to IPV4

Why can't I control the module with UART on Raspberry Pi, can't open ttyS0 through minicom, prompting any ttyS0?

• Open the Raspberry Pi terminal and input the following commands:

sudo raspi-config
Select Interfacing Options -> Serial to turn off shell access and turn on the hardware serial port

Raspberry Pi 2B/zero, the user serial device number is ttyAMA0; you can use the following command line to confirm that serial0 is the selected serial device number, as follows:

ls -l /dev/serial*

Why is the command sent not displayed after sending an AT command and returning OK?

The SIM7600X can send the following command plus carriage return, and successfully turn on the display after displaying OK.

ATE1
