Working With Windows

Hardware Preparation

  • In addition to the items in the package,
    5G-HAT-Pack.jpg
  • you need to prepare the following items:
* A 5G SIM card (no downtime and 5G enabled);
* A computer with a Windows operating system （Such as Windows 10）
* A headphone cable with a microphone (optional);

Hardware Connection

Connect the 5G HAT with a usb3.0 cable, and connect an external 5V power supply to the Type-C power supply port of the 5G HAT, as shown in the figure:
M.2-TO-4G-5G-HAT-TO-WIN10.jpg

Install drivers

  • After connecting the 5G HAT to the computer through a double-ended usb3.0 data cable, there will be a series of devices without drivers installed on other devices:

RM500U-driver-manager.png

  • Download the driver to your computer and unzip the compressed package.
  • Enter the RM50X_Driver directory.
  • Click setup.exe to install the driver. After the installation is complete, the device manager will generate the following devices:

SIM Card Selection

Dual SIM Card Switching

The 5G HAT has two SIM card slots onboard, a dual SIM card, and single standby, which can be switched and enabled by AT command.

  • SIM card 1 is selected by default, You can use the following command to query and confirm:
AT+QUIMSLOT?
  • To switch SIM card 2, please use the following command:
AT+QUIMSLOT=2
  • Switch back to SIM card 1, please use the following command:
AT+QUIMSLOT=1
  • Check whether the corresponding card slot recognizes the SIM card:
AT+CPIN?
RM500U-CN and RM500Q-GL support Dual SIMs, but RM500Q-AE and RM502Q-AE modules do not support dual SIM cards.

Network Speed Test

RM50XQ Network Speed Test
  • Install speed testing software, such as Internet speed manager and other speed testing software, you can choose to download the speed test at www.speedtest.cn/pc/download.

About the speed testing

As there will be many inconsistencies between actual and laboratory conditions that will result in 5G speeds that are not ideally stable at 100MBPS, there are the following.

  • Base station distance, the closer to the 5G base station the better the signal and the faster the speed.
  • Base station load, the fewer people using it the faster it will be, and the slower it will be during peak commuting periods.
  • Number of base stations: due to the spectrum, an equal amount of 4G coverage requires double the number of 5G base stations.
  • Operator: you need to confirm your 5G card, and whether the speed is limited, you can regularly ask the operator to reset your network.
  • Indoor is worse than outdoor: building penetration attenuation, and indoor bypass attenuation.

PS: The current number of base stations still does not have good coverage, and the speed measurement is not quite the same in different locations.

MBIM Dial-up Internet Access

  • Download and install the driver.
  • Open the RM50X AT port and send the following commands to dial up the Internet:
AT+QENG="servingcell"
AT+QCFG="usbnet",2
AT+CFUN=1,1
  • After dialing and restarting, the mobile network card appears on the computer network connection interface, and the dialing is successful.

GPS Positioning

Connect the passive GPS antenna to the GNSS antenna interface of the module(RM500Q-GL is ANT2;RM500Q-AE and RM502Q-AE is ANT3), and place the antenna outdoors facing the sky. Then send the AT command to turn on the GPS:

AT+QGPS=1        //Turn on GPS positioning
AT+QGPSLOC=0     //Get GPS positioning

RM50XQ-GNSS-01.png
Now open the NEMA port, you can get GPS data:

Working with Raspberry Pi

The use of Raspberry Pi OS

This configuration is only needed for the first time.

Please download the newest Raspberry Pi OS, All the settings are based on Kernel 5.5, if you use the old version, please update first. Make sure your Kernel version is up-to-date, or else you may face issues with the driver.

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.

Step 3. Networking Setup with AT Commands

AT+QCFG="usbnet",1
AT+CGDCONT=1,"IPV4V6","YOUR_APN" 
AT+CFUN=1,1

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.

RM500U RNDIS DIAL.png

  • After rebooting the module, the NET indicator is on, and you can use the following commands to check the network. (Optional)
AT+QENG="servingcell"
  • Use the following commands to get the IP and set up the DNS:
sudo dhclient -v usb0
sudo apt-get install udhcpc
sudo udhcpc -i usb0
sudo route add -net 0.0.0.0 usb0

Step 4. Test 5G Network

After dialing, the Raspberry Pi can see usb0 get the ip by the following command, enter the command ifconfig usb0 or ifconfig.

  • Now check the assigned IP address and test the connection.
ifconfig usb0

RM500U-jetson.png

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.
lsusb

RM500Q GL VID PID.png
Added VID sum PID.

sudo apt-get install unzip
wget https://files.waveshare.com/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*

Jetson-nano-vid.png

RNDIS

  • Enable minicom.
sudo apt-get install minicom
sudo minicom -D /dev/ttyUSB2
  • Send the following command ECM in minicom.
AT+CPIN?
AT+QCFG="usbnet",3
AT+CFUN=1,1

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

AT+QENG="servingcell"

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 0.0.0.0 usb1

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

ip route

FAQ

Question:What should I do if there's a power loss?

 Answer:

5G consumes a lot of power, and the host's USB interface might not provide enough power. Please use a USB double-plug cable to supply sufficient power to the module, as shown in the diagram.
RM500-CN-5G-HAT-FAQ.jpg

{{{5}}}


Question:How can I switch the SIM card?

 Answer:

As RM500U-CN and RM500Q-GL modules support simultaneous access to two SIM cards, dual-card single standby, can be switched to enable one of the SIM cards to work through the AT command: 

*SIM card 1 is used by default, you can use the following commands to check: 
 AT+QUIMSLOT?
*Switch to SIM card 2 using the following commands:  
 AT+QUIMSLOT=2
*Switch to SIM card using the following commands:  
 AT+QUIMSLOT=1
*Query whether the corresponding card slot identifies the SIM card:  
 AT+CPIN?

Question:How to configure when I'm using RPI with Ubuntu and RM500Q-GL 5G HAT?

 Answer:

1. The Ubuntu system can only be used by dial-up Internet access, please refer to the following steps for dial-up Internet access. 

AT+CPIN? 
AT+QENG="servingcell" 
AT+QCFG="usbnet",1
AT+CFUN=1,1

RM500U RNDIS DIAL.png
2. If it still doesn't work, please use the following command to check the network status: 

AT+CPIN?
AT+COPS?
AT+QCSQ
AT+QENG="servingcell"

3. Make sure your mobile network connection is working properly. Insert the SIM card into the device and make sure it is activated and has sufficient signal strength. You can try to test the same SIM card on other devices to rule out the possibility of SIM card failure. It is also recommended that you use SIM cards of different operators to compare and test, to rule out the problem of carrier frequency band support.
