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.
- 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.

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.
