Interface

Usage

Warning:Do not operate when in power on (don’t plug or unplug the Antenna, SIM Cars, SD Card, in case of short-circuiting that may burn the IC down.)

Hardware connecttion

1. Plug the SIM card into the board.
2. Plug the GPS antenna into the interface.
3. Plug two 4G-GSM antennas into the main antenna interface and auxiliary one.
4. Plug the headphone with the microphone.
5. Plug the SD card into the SD card slot for SIM7600.
When powering the board and the SIM7600 module working, the onboard PWR LED will turn on. When the SIM working, the NET LED will flash.

How to use AT commands

For using AT commands by the serial communication, it needs to upload the sketch to this board. The sketch is available on GitHub.
1. Open the sketch by Arduino IDE.
2. Use Type-C USB cable to connect the board and PC, note plug the cable to USB-MCU interface.
3. Select "Tool --> Board --> Arduino Zero" and the port.

4. Verify the code and upload.
5. Open the serial monitor, send the AT command to the board, and it will print the module response.
6. There are some demos that show how to use the AT commands:

• AT commands test
  

    AT+CGMI    // Request manufacturer identification
    AT+CGMM    // Request model identification
    AT+CGSN    // Request product serial number identification
    AT+CSUB    // Request the module version and chip

    AT+CPIN?     // Request the state of the SIM card
    AT+CICCID    // Read ICCID from SIM card
    AT+CNUM      // Request the subscriber number
    AT+CNMP?     // Preferred mode selection
    AT+COPS?     // Check the current network operator

    AT+IPREX?    // Check local baud rate
    AT+CRESET    // Reset the module

• Get the GNSS location

    AT+CGPS=1      // Start GPS session 
    AT+CGPSINFO    // Get GPS fixed position information
    AT+CGPS=0      // Stop GPS session

• Send and receive SMS

Note that is recommended to use other serial monitors not the Arduino IDE one to send the AT command for this demo.

    AT+CSCA="XXXXXX"       // Set the SMS service centre address
    AT+CMGF=1              // Select SMS message format
    AT+CMGS="xxxxxx"       // Send message to "xxxxxx"(the receiver number).

After sending the above AT commands, it will show ">" and then you can send you message. when you finish your message, you need to send "1A" with hexadecimal for confirming or send "1B" with hexadecimal for cancel, that is why recommended to use other serial monitor.

    AT+CMGR=3        // Read message
    AT+CMGD=3        // Delete message

• Make a call

    AT+CSDVC         // Switch voice channel device
    AT+CSDVC=1       // 1-Handset, 3-Speaker phone
    AT+CLVL=2        // Set loudspeaker volume level to 2, the level range is 0 to 5

    ATDxxxxx;        // Call to xxxxx
    AT+CHUP          // Hang up the call

    AT+CLIP=1     // Calling line identification presentation
    ATA         // Call answer

• HTTP test

    AT+HTTPINIT         // Initialize and start the HTTP
    AT+HTTPPARA="URL","http://www.makerfabs.com"  // Set the URL
    AT+HTTPACTION=0    // Connect the HTTP. (0-get, 1-post, 2-head)
    AT+HTTPHEAD        // Read the response's header.
    AT+HTTPREAD=0,3    // Read the content (“3” means the number of the reading data)

• Test the SD card for SIM7600

When you plug an SD card into the SD card slot for SIM7600, You can use the following commands to check it.

    AT+FSCD=D:                    // Select SD card directory as current directory
    AT+FSLS                       // List directories/files in current directory
    AT+CFTRANRX="D: TEST.txt",10  // Transfer a file to EFS
    AT+CFTRANTX="D: TEST.txt"     // Transfer a file from EFS to host

Test SD card for MCU

When you have plugged the SD card into the SD card slot for MCU, it can not use the AT commands to read or write. There is a demo shows how to read and write the SD card for MCU.

• It is required to upload a sketch to the board. The sketch is available on GitHub.
  
• Open the sketch by Arduino IDE.
  
• Use Type-C USB cable to connect the board and PC, note plug the cable to USB-MCU interface.
  
• Select "Tool --> Board --> Arduino Zero" and the port.
  
• Verify the code and upload.
  
• Open the serial monitor, it will print the information of the SD card.
  

Surfing the internet

Maduino Zero 4G LTE CAT1 can be a wireless networking device to support the PC or Raspberry PI surfing the internet. Next, it will show how to do it.

• It needs to install the SIM7600 driver to the PC, the driver is available on Resources.
  
• Use Type-C USB cable to connect the board and PC, note plug the cable into the USB for SIM7600.
  
• Download the driver to the PC.
  
• Follow the below step to install the driver manually:
  

1. Open "Device Manager".

2. In "Device Manager", select "Other devices".

3. Right-click on and click "Update Driver Software".

4. Select "Browse my computer for driver software".

5. Paste the location address of the driver into the location field, then click "Next".

6. Wait until the driver installation process completes.

• If the PC does not connect to the internet through this device, please open the serial monitor and send the AT command to start the networking.
  

    AT$QCRMCALL=1,1

If have not yet, please use the PPP dial-up connection way to start networking.
