User Guide

Testing it in Windows PC

1. Hardware connection and driver installation
  • Before testing, you should prepare
    • A Micro USB cable
    • LTE and GPS Antennas
    • The SIM7070G Cat-M/NB-IoT/GPRS HAT
    • An NB-IoT SIM card.
  • Insert the SIM card into the SIM7070 board, and connect the LTE antenna and the GPS antenna. Connect the micro USB of the SIM7070G board to the PC by USB cable.
  • Hold the PWRKEY button for about 1s to power on the module. After powering on, the STA indicator lights on, NET indicator quick-blinks first and then slow-blinks.
  • Download the driver file, unzip it. Then update the driver by Devices Manager
  • Generally, the SIM7070G will be recognized by a PC with three USB ports. To update the driver, you can right-click the USB port and update it with the driver downloaded
  • AT Port COM31 is the one used as the communication port. We will use it to test the SIM7080G board.

Note: The SIM7070G modules support global networks. The time to log in to the network is different among different areas. To use the SIM7070G, you should first confirm that LTE-M or LTE-NB networks are available in the local area.

Use it with Raspberry Pi

Initialize IO and install software

The PWRKEY pin is connected to P7 (wiringPi number) of Raspberry Pi by jumper. To let the SIM7080G board work normally, you should firstly initialize the P7 pin. Download codes and run by the following commands.

sudo apt-get update
sudo pip install RPi.GPIO
sudo apt-get install python-serial
wget -P ~/Documents/ https://files.waveshare.com/upload/4/4b/SIM7070G_Cat_M_NB_IoT_HAT_Code.tar.gz
cd ~/Documents
tar -xzf SIM7070G_Cat_M_NB_IoT_HAT_Code.tar.gz
sh ~/Documents/SIM7070G_Cat_M_NB_IoT_HAT_Code/RaspberryPi/pi_gpio_init.sh
sudo pip install RPi.GPIO
sudo apt-get install python-serial
Enable UART and hardware connection

Open raspi-config by following commands, and choose Interfacing Options -> Serial, close login sheel and open the hardware serial port.

sudo rapsi-config
