Hardware Configration of the New Version

In the second half of 2021, the SIM7600 series boards will be switched to new versions for shipment. The old and new versions can be used normally and stably.Compared with the old version, the new version has the following changes:

SIM7600 NEW old-V2.jpg
  • 1) Newly added 330uF electrolytic capacitor (Stronger voltage stabilization ability)
  • 2) Newly added PWR and Flightmode pin jumpers (Automatic power-on function can be set, and the IO port can be customized to control the switch and Flight mode)
  • 3) Add solderable pads for VCCIO.(when used with Raspberry Pi, the SIM7600X 4G HAT is soldered at 3.3V working level by default; if you need to use 5V working-level MCU, you can change it to 5V by yourself)
  • 4) Add solderable pads for the module USB. (if you don’t want to use a USB adapter cable, you can solder them to the corresponding USB solder joints at the bottom of the Raspberry Pi through some flying cables. This operation should be used with caution by non-professionals)
  • 5) The power management IC was changed from MP1482 to SPX29302
  • 6) The silkscreen naming is changed from "WPI naming" to "BCM naming"
  • 7) Fine-tuning the layout
  • 8) Add new solder joints for module Boot to burn the firmware forcibly. Short-circuit the two pads can enter the forced firmware burning mode. (Only used when the firmware cannot be burned normally)

Description of turning on/off the HAT for New Version

  • In the new version, PWR and 3V3 are short-circuited by default, so the HAT turned on automatically after connecting to the power supply.
  • If you need to use the PWRKEY button to turn on/off the HAT, please remove the jumper cap between PWR and 3V3:
  • If you want to use the Raspberry Pi to turn on/off, please set the jumper cap between PWR and D6:
SIM7600X Power.png

Flight mode description of the New Version

  • The new version of the HAT doesn't turn on the Flight mode by default:
  • If you need to control the Flight mode through the Raspberry Pi pins, set the jumper cap between Flight and D4:
SIM7600X Flight.png

UART configuration of Raspberry Pi

Since the Raspberry Pi UART 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

Choose Interfacing Options -> Serial -> no -> yes to disable Linux's use of console UART:

Sim7600CE-27 (1).jpg

Open /boot/config.txt file, and find the below statement. If there is no line, you can directly add it at the end of the file.

enable_uart=1

And then reboot the system.

Minicom for UART debugging on Raspberry Pi

1. Insert the module into the Raspberry Pi.
2. Install minicom, minicom is a text-based modem control and terminal emulation program for Linux:

sudo apt-get install minicom

3. Execute command: minicom -D /dev/ttyS0(ttyS0 is the UART of Raspberry Pi 3B)

  • Baud rate is 115200 by default. If you need to change the baud rate, for example, 9600, you can add the parameter -b 9600.
  • The user UART device of Raspberry Pi 2B/Zero is ttyAMA0, and ttyS0 of Raspberry Pi 3B.

4. Take the AT synchronization test as an example, and send related commands, as shown in the picture below:

Sim7600CE-29.jpg

Minicom can enter the setting mode by pressing Ctrl+A then pressing Z, and selecting X to exit.

Download the demo

1. Insert the module into the Raspberry Pi
2. Download the demo to /home/pi/ directory:

wget https://files.waveshare.com/upload/2/29/SIM7600X-4G-HAT-Demo.7z
sudo apt-get install p7zip-full
7z x SIM7600X-4G-HAT-Demo.7z   -r -o/home/pi
sudo chmod 777 -R /home/pi/SIM7600X-4G-HAT-Demo

3. Enter the bcm2835 directory, compile and install the BCM2835 library:

chmod +x configure && ./configure && sudo make && sudo make install

4. Enter to the corresponding demo directory, compile and run the demo, here we take PhoneCall demo as an example:

sudo make clean          //Clear the original execution file
sudo make              //recompile
sudo ./PhoneCall       //Run the program

Combination command:

sudo make clean && sudo make && sudo ./PhoneCall

FAQ

 Answer:

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


 Answer:

In this case, it may be that you have not successfully connected to the network, you can follow the steps below to troubleshoot:
1. First check the hardware connection:

  • Check if the MAIN antenna is well connected;
  • Whether the connected SIM card can call and surf the Internet normally on mobile phones and other devices:
  • If the Raspberry Pi is connected, whether the module enters airplane mode;

2. After confirming that there is no problem with the hardware, the software can use these instructions:

  • Check whether the sim card is in good contact: AT+CPIN?
  • Check if the network mode setting is correct: AT+CNMP?
  • Check the signal quality of the current environment: AT+CSQ
  • Check the operator's access situation: AT+COPS?
  • Check the connection status: AT+CPSI?
  • Check whether it is successfully registered to the network: AT+CGREG?

SIM7600X network check.png


 Answer:

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


 Answer:

It may be that the APN has not been obtained. Generally, the APN can be obtained automatically. In some areas (IoT card), it needs to be obtained manually. For example, it can be set by the following instructions:

AT+CGDCONT=1,"IP","CMNET" //CMNET is the apn of China Mobile, which is different for different operators
SIM7600X apn.png


 Answer:
  • Under normal circumstances, SIM7600X has been automatically dialed after receiving the Windows system, and there is no need to repeat dialing. Repeated dialing will return NO CARRIER
  • If you still can't dial-up Internet access, please use the following command to change to Windows default dial-up Internet access mode
    AT+CUSBPIDSWITCH=9001,1,1 
  • The display is turned off, the mobile network is not enabled, you can ignore it and go online directly;

SIM7600X rndis dial-up (1).png

SIM7600X rndis dial-up (2).png

  • The network card display is enabled after installing the driver

SIM7600X rndis dial-up (3).png


 Answer:
  • 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

SIM7600X-FAQ (4).png

  • If 4G has been fixed, the speed is still not ideal, it may be a frequency band problem;
AT+CNBP? //Back up the current frequency band (the returned frequency band information can be copied to notepad, etc.)
AT+CNBP=0x0002000000400183,0x000001E000000000,0x0000000000000021 //After returning OK, measure the speed
AT+CNBP=0x0002000004400180,0x000001E000000000,0x000000000000003F //If the speed does not improve, try this

 Answer:

SIM7600X-FAQ (6).png
1. Pay attention to check the device manager, the new device will be prompted during the upgrade process, and there will be no device driver during the first upgrade;
2. Pay attention to the USB cable. The speed of the USB cable is higher during the upgrade process. You need to choose a better quality USB cable to avoid poor contact.
3. You need to run the upgrade tool with administrator privileges (SIM7500_SIM7600_QDL V1.41 only for Update)
4. Uninstall and reinstall the upgrade tool (SIM7500_SIM7600_QDL V1.41 only for Update)
5. For more operation details, please refer to this video: https://www.waveshare.net/wiki/SIM7600-Firmware-upgrade-Video
