Line 1: Line 1:
supports LTE (4G) communication which is much faster and popular than 2G.
'''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.)<br>
===Hardware connecttion===
1. Plug the SIM card into the board.<br>
2. Plug the GPS antenna into the interface.<br>
3. Plug two 4G-GSM antennas into the main antenna interface and auxiliary one. <br>
4. Plug the headphone with the microphone.<br>
5. Plug the SD card into the SD card slot for SIM7600.<br>
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.<br>
===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.<br>
1. Open the sketch by Arduino IDE.<br>
2. Use Type-C USB cable to connect the board and PC, note plug the cable to USB-MCU interface.<br>
3. Select "Tool --> Board --> Arduino Zero" and the port.<br>
4. Verify the code and upload.<br>
5. Open the serial monitor, send the AT command to the board, and it will print the module response.<br>
6. There are some demos that show how to use the AT commands:<br>
:* '''AT commands test'''<br>
    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 monitor 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.<br>
    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    // Calling line identification presentation
    ATA        // Call answer
:*'''HTTP test'''
:*'''Test the SD card'''
: When you plug an SD card into the SD card slot for SIM7600, You can use the following commands to check it.<br>
:*'''More AT commands detail please check [ here]'''
