Connect Waveshare SIM7600X-4G-HAT(B) to Raspberry Pi Zero W/2 W

A. Set up driver

1. Find IP address of Raspberry Pi

After boot Raspberry Pi OS (with local wifi), find IP address of Pi:

on Ubuntu:

sudo apt-get install arp-scan

ifconfig ## Get device network

sudo arp-scan --interface=[device network] --localnet

ssh to Pi using user and password that was set in setup process

2. Get HAT package

wget https://www.waveshare.com/w/upload/4/4e/SIM7600X-4G-HAT%28B%29-Demo.7z

3. Install driver

sudo apt-get install p7zip-full

7z x 'SIM7600X-4G-HAT(B)-Demo.7z' -r -o/home/pi

mv /home/pi/'SIM7600X-4G-HAT(B)-Demo' /home/pi/SIM7600X-4G-HAT-B-Demo

sudo chmod 777 -R /home/pi/SIM7600X-4G-HAT-B-Demo

sudo nano /etc/rc.local

Add the following line to rc.local to start Waveshare 4G HAT drivers on the boot-up of the Raspberry Pi.

sh /home/pi/SIM7600X-4G-HAT-B-Demo/Raspberry/c/sim7600_4G_hat_init

Install driver

cd /home/pi/SIM7600X-4G-HAT-Demo/Raspberry/c/bcm2835

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

B. Setup RNDIS for SIM7600G HAT to work like a network card

1. Check if HAT is recognized

ls /dev/ttyUSB*

2. Run AT command

python3 example/AT-test.py

Send the follwing command to switch to RNDIS

AT+CUSBPIDSWITCH=9011,1,1

Check if the setup was successfully

ifconfig
