Quectel RM520N Module for Jetson

The RM520N is a series of 5G IoT modules specially optimized for IoT/eMBB applications, designed in an M.2 form factor in accordance with the 3GPP Release 16 specification, which supports both 5G NSA and SA modes. The RM520N is compatible with Quectel’s 5G module series RM50xQ, LTE-A Cat 6 module EM06, Cat 12 module series EM12/EM12xR/EM120K, and Cat 16 module EM160R-GL, facilitating migration from LTE-A to 5G.

The RM520N is an industrial-grade module for industrial and commercial applications only. It covers nearly all the mainstream carriers worldwide and supports Qualcomm® IZat location technology Gen9C Lite (GPS, GLONASS, BDS and Galileo). The integrated GNSS receiver greatly simplifies the product design and provides quicker, more accurate and dependable positioning capability.

Thanks to a rich set of Internet protocols, industry-standard interfaces and abundant functionalities (USB and PCIe drivers for Windows 10, Linux, and Android) the module can be adopted in a wide range of eMBB and IoT applications including industrial routers, home gateways, STB, industrial laptops, consumer laptops, industrial PDAs, rugged tablet PCs, video transmission, and digital signage.

Hardware Connection​

danger

In this wiki, we will use the reComputer Robotics J3011 as an example to demonstrate how to install and configure a RM520N-GL module on Jetson device.

Step1. Prepare all materials that will be used.

  • reComputer Robotics J4012 equipped with Jetpack 6.2
  • Quectel RM520N-GL Module

Step 2. Adjust the position of the support screw.

Step 3. Insert the 5G module into the M.2 Key B port.

Step 4. Tighten the fixing screws and install the antenna.

Step 5. Install the 5G SIM card in the front panel.

Configure the 5G Module​

Start the Jetson device and enter the following command in the terminal.

sudo apt install minicom
sudo minicom -D /dev/ttyUSB2

In the minicom interface, we can use AT commands to configure the operation mode of the 5G module.

AT+CPIN? # Check SIM card status. A normal response is READY.
AT+QCFG="usbnet",3 # Set module operation mode to RNDIS. A normal response is OK.
AT+CFUN=1,1 # Restart the module. If it fails to start for an extended period, try restarting the Jetson device.
AT+QNWPREFCFG="mode_pref",AUTO # Set automatic network mode or prioritize LTE network mode
AT+QNWPREFCFG="mode_pref",LTE

If everything goes smoothly, your device should now be able to access the internet normally.

To verify the network quality, you can use a speed test tool to test the network speed.

Known issue: We have found that this configuration method allows the 5G module to connect to the network normally, but the mmcli information displays anomalies.
