VIM3 RM500Q 5G NR Module
Introduction
This page will introduce the usage of RM500Q 5G NR module.You will learn how to use the 5G module on Khadas SBC.
Preparation
- Disconnect the Khadas SBC power port cable.
- Insert the 5G module board into the M.2 slot on M2X WWAN Extension board.
- Insert the M2X WWAN Extension board into the SBC.
- Insert a valid
Nano SIMcard on the 5G module.
Linux
Upgrade System
You need to Upgrade System to latest version.
Enable PCIe Port (VIM3 Only)
If you use the VIM3 board, you need to enable the PCIe function.
Khadas VIM3 PCIe/USB3.0 share one data port,and the default mode is USB 3.0.So when we need to use 5G module, we need to switch it to PCIe port.
$ echo 1 > /sys/class/mcu/usb_pcie_switch_mode $ sudo reboot
Reboot the system to bring changes into effect.
Disable ModemManager
As the ModemManager doesn't support this 5G modem, so you have to disable it and use Quectel QConnectManager to connect to the internet.
$ sudo systemctl stop ModemManager.service $ sudo systemctl disable ModemManager.service
Setup Quectel QConnectManager
You need to use Quectel QConnectManager to connect to the internet.
Get Source Code
$ git clone https://github.com/numbqq/quectel-CM.git
Compile the Source Code
$ cd quectel-CM $ make
Configure the Network
Connect to Internet
Execute the command below to connect to internet.
$ sudo ./quectel-CM &
Check the Network Node
$ ifconfig rmnet_mhi0.1
rmnet_mhi0.1 Link encap:UNSPEC HWaddr 02-50-F4-00-00-00-00-00-00-00-00-00-00-00-00-00

$ echo "nameserver 1.0.0.1" | sudo tee /etc/resolv.conf
Check Network
$ ping -I rmnet_mhi0.1 khadas.com
