5G ECM Mode Dial-up

Step 1. Uninstall Modem Manager and Network Manager

Open a terminal and run the following commands to uninstall Modem Manager and Network Manager:

sudo apt purge modemmanager -y
sudo apt purge network-manager -y

Step 2. Test 5G Module

  • Driver Testing:
    Make sure the option USB-serial driver is properly loaded to the module interfaces. Check it with the usb-devices command.

  • Testing with AT command:
sudo apt-get install minicom
sudo minicom -D /dev/ttyUSB2
Welcome to minicom 2.7.1

Compiled on Aug 13 2017, 15:25:34.
Port /dev/ttyUSB2

Press CTRL-A Z for help on special keys


Step 3. Networking Setup with AT Commands


Wait for the modem to boot again. It may take 30 seconds. Once the modem reboots, the minicom will be activated again.

After the reboot, open a new Linux terminal and check for usbX in the network interface using ifconfig or ipaddr commands.

Step 4. Test 5G Network

Once the internet is active you should see usbX in your internet interface. You can use ifconfig or ipaddr and look for usbX interface.

  • Now check the assigned IP address and test the connection.

5G HAT Power or Reset Control

The 5G HAT is provided with PWR and RESET control pins, and the Raspberry Pi can control the module power on/off or reset through the high and low levels of these two pins.

  • Turn the PWR and RST setting switches to the right to enable Pi control:
  • Power Control: The following demonstrates the Shell script to control the PWR (D5 PIN) as an example:
cd /sys/class/gpio
echo 5 > export

cd gpio5
echo out > direction
echo 1 > value    #set to high level to shut down the 5G module
echo 0 > value    #set to low level to power on the 5G module
echo 5 > unexport
  • Reset Control: The following demonstrates the Shell script to control the Reset (D6 PIN) as an example:
cd /sys/class/gpio
echo 6 > export

cd gpio6
echo out > direction
echo 1 > value    #set to a high level to shut down the 5G module
sleep 1           #wait for 1 second
echo 0 > value    #set to low level to power on the 5G module
echo 5 > unexport

The use of OpenWRT

Introduction to OpenWRT

Soft routing is using desktops or servers and other equipment with software. It mainly depends on the settings of the software to achieve the functions of the router. The hard routing is a unique hardware device, including a processor, power supply, and embedded software to provide router functionality.
OpenWrt is a very popular soft routing system. It is a highly modular and highly automated embedded Linux system with powerful network components and scalability. It is often used in industrial control equipment, routers, and other equipment.
In addition to the functions of general home routers, OpenWrt soft routing can also achieve port forwarding, intranet penetration, 4G networking, FTP server and more powerful functions.

5G network speed test

In the speed measurement part, because the Raspberry Pi comes with a Gigabit Ethernet port, and there are few USB network cards above Gigabit, we use the SpeedTest For Python tool to perform speed measurement by the commands. Connect to the terminal of OpenWrt and enter the commands one by one to measure the speed:

## Raspberry Pi OS
sudo apt install speedtest-cli
speedtest      # or use speedtest_cli


## OpenWRT
opkg update   
opkg install python3
opkg install python3-pip
pip install speedtest_cli 
speedtest      # or use speedtest_cli

Working with Jetson Nano

Hardware Connection

Connect the 5G HAT with a double-ended usb3.0 data cable, and connect an external 5V power supply to the Type-C power supply port of the 5G HAT, as shown in the figure:

Load USB Device Descriptor

In order to identify the module, the module's VID and PID information needs to be added to the file [kernel]

  • View VID and PID of RM500U

Added VID sum PID

sudo apt-get install unzip
wget https://www.waveshare.com/w/upload/0/09/RM5XXQ_For_Jetson_nano.zip
unzip RM5XXQ_For_Jetson_nano.zip
sudo chmod 777 -R RM5XXQ_For_Jetson_nano
cd RM5XXQ_For_Jetson_nano
sudo ./install.sh
sudo reboot
Please do not delete or modify the four directory files of option directory, default.script and install.sh, otherwise it will affect the loading of device descriptors!

After successfully adding the PID and restarting Jetson nano, enter the following command in the command line interface to display five device symbols USB0-USB4

ls /dev/ttyUSB*



  • Enable minicom.
sudo apt-get install minicom
sudo minicom -D /dev/ttyUSB2
  • Send the following command ECM in minicom.

After the module restarts, and the NET light is on, use the following command to check the network status (optional).


Get the IP and set the DNS with the following commands:

sudo dhclient -v usb1
sudo apt-get install udhcpc
sudo udhcpc -i usb1
sudo route add -net usb1

After dialing, you can see that usb1 gets the IP through the following command:

ip route

Test usb1 networking status.

 ping -I usb1 www.baidu.com




Assembly drawing



RM500U-CN is based on the UNISOC platform, mainly used in China.


The 5G module consumes a lot of power, especially at the moment of network access; the Raspberry Pi has limited power supply capacity, and can be powered by a 5V (3A) power supply through the onboard TYPE-C interface.



If usbX interface is not visible reboot your whole system, and check your SIM, antenna, module, and USB. Then check the configuration of the module.

AT+QCFG="usbnet" # Should return 1

Check the SIM is detected by the module.

AT+CPIN? # Should return READY

Check if the module is registered to the network.

AT+CEREG? # Should return 0,1 or 0,5

Check the APN is right and has an IP.

AT+CGCONTRDP # Should return the APN details and IP address.
