SIM7600CE-T/E-H/A-H/G-H 4G Modules

Introduction

The SIM7600X 4G HAT is a 4G/3G/2G communication and GNSS positioning module, which supports LTE CAT4 up to 150Mbps for downlink data transfer. it is pretty low power consumption.

You can connect this 4G module with a computer to surf the Internet or attach it onto Raspberry Pi to enable functions like 4G high-speed connection, wireless communication, making telephone calls, sending SMS, global positioning, etc.

Testing

Hardware setting

• This module comes with GSM antenna, LTE antenna and micro USB cable. Besides these you should prepare:
  • A 4G sim card
  • A microphone cable
  • A Micro SD card (Optional)
• Insert the SIM card to the card slot, Insert the headphone cable and connect the LTE antenna.
  

• 

  back side
• 

  front size

• Connect the USB interface of SIM7600E-H 4G HAT to PC with a micro USB cable. Then the PWR indicator will keep bright.
• Press the PWRKEY button and hold for 1s, the NET indicator will blink 1 time per second.
• Open Device Manager to check the COM ports
  
• Install SIM7600 driver(driver)

【Note】The default hardware of SIM7600CE 4G HAT needs to be turned on by button. If the hardware needs to be turned on automatically, you can use a connection line to connect the PWR and GND pins on the module pin, so that it can automatically turn on, as shown in the figure below

Working with Raspberry Pi

Hardware connection

The relationship between SIM7600 control pins and Raspberry Pi IOs is shown in Table：

SIM7600X 4G HAT	Raspberry Pi
5V	5V
GND	GND
RXD	TXD (BCM: 14)
TXD	RXD (BCM: 15)
PWR	P22 (BCM: P6)
FLIGHTMODE	P7 (BCM: P4), high active

Initialize Raspberry Pi

You need to set the SIM7600 module to the working mode first.

• Download demo codesdemo codes，unzip it and recommend the folder Rspberry Pi/c as SIM7600X，and sopy it to /home/pi directory of Raspberry Pi
• Go to /home/pi/SIM7600X directory and run the following command.

chmod 777 sim7600_4G_hat_init

• Set auto-run when booting:

sudo nano /etc/rc.local

• Add the line below in the from of exit 0：

sh /home/pi/SIM7600X/sim7600_4G_hat_init

Enable serial port

For proper use, you need to disable the login shell and enable the hardware serial.

sudo raspi-config

Choose Interfacing Options ->Serial ->no -> yes，

Networking via wwan0 Interface

1、Connect the USB interface of SIM7600 module to Rasberry Pi by USB cable

2、Use ifconfig command to check wwan0 interface.

3、Install libqmi and udhcpc

sudo apt-get install libqmi-utils udhcpc -y

3、Check the status of wwan0 interface：

sudo qmicli -d /dev/cdc-wdm0 --dms-get-operating-mode

If the status is not online, you need to run the following command to configure it and test again.

sudo qmicli -d /dev/cdc-wdm0 --dms-set-operating-mode='online'

4、Set wwan0 network

sudo qmicli -d /dev/cdc-wdm0 -w	
sudo ip link set wwan0 down	
sudo echo 'Y' | sudo tee /sys/class/net/wwan0/qmi/raw_ip
sudo ip link set wwan0 up

5、 Set APN and connect to network.

sudo qmicli -p -d /dev/cdc-wdm0 --device-open-net='net-raw-ip|net-no-qos-header' --wds-start-network="apn='YOUR_APN',username='YOUR_USERNAME',password='YOUR_PASSWORD',ip-type=4" --client-no-release-cid

Note: the apn, username, password and other parameters should be modified according to the actual situation.

The user name of APN can be ignore sometimes. For examples:

sudo qmicli -p -d /dev/cdc-wdm0 --device-open-net='net-raw-ip|net-no-qos-header' --wds-start-network="apn='CMNET',ip-type=4" --client-no-release-cid

6、User udhcpc to set router and IP

 sudo udhcpc -i wwan0

7、Now you can disconnect the RJ45, turn off the WiFi and test the 4G network.
