5G Module Usage

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

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  
          inet addr:10.129.59.93  Mask:255.255.255.252
          inet6 addr: fe80::50:f4ff:fe00:0/64 Scope:Link
          UP RUNNING NOARP  MTU:1500  Metric:1
          RX packets:1089360 errors:0 dropped:0 overruns:0 frame:0
          TX packets:176581 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:1521449058 (1.4 GiB)  TX bytes:57525792 (54.8 MiB)

If you can see the IP address inet addr mean the network is fine.

Setup DNS

You also need to setup the DNS.

$  echo "nameserver 1.0.0.1" | sudo tee /etc/resolv.conf

Check Network

$  ping -I rmnet_mhi0.1 khadas.com

Check Whether use 5G Network

Andoid

It will support automaticly.
