Dial-up Networking with Raspbian

• When using Raspberry Pi Zero/Zero W, you can connect it to the 4G HAT through the thimble, no additional USB cable is required;
• if it is used on other Raspberry Pi boards, you can connect the 4G HAT to the Raspberry Pi through a Micro USB cable. The connection is as follows:

• And use the following method to Dial-up Networking
• Raspberry Pi networked via RNDIS
• Raspberry Pi networked via NDIS
• SIM868 PPP Dail-up Networking
• How to turn Raspberry Pi Zero W into a 3G 4G Router

Minicom Serial Debugging

• 1. Connect the HAT to your Pi through the USB cable.
• 2. Install minicom:

sudo apt-get install minicom

• 3. Execute the following command:

sudo minicom -D /dev/ttyUSB2

The default baud rate is 115200.

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

Press Ctrl+A, then press Z, the minicom can enter the setting mode, and press X to exit.

Sample Demo

1. Inset the module and connect to the Raspberry Pi.

2. Download the sample demo to /home/pi/:

wget https://files.waveshare.com/upload/4/4e/SIM7600G-H-4G-HAT-B-Demo.zip
sudo apt-get install p7zip-full
7z x SIM7600G-H-4G-HAT-B-Demo.zip 
sudo chmod 777 -R SIM7600G-H-4G-HAT-B-Demo

3. Respectively enter the corresponding directory, compile and run the demo. The related instructions are shown below (Take the PhoneCall.py demo as an example):

cd SIM7600G-H-4G-HAT-B-Demo/Raspberry/python/PhoneCall/      
sudo apt-get install python3-pip
sudo pip3 install pyserial
sudo pip3 install RPi.GPIO
sudo python3 Phonecall.py
