NVIDIA Jetson Orin Nano

Developer Kit

The NVIDIA Jetson Orin Nano Developer Kit is a compact edge AI platform designed for computer vision, robotics, and intelligent IoT applications. When integrated with Monogoto connectivity, it can operate over public cellular networks, private LTE/5G networks, and satellite IoT services, depending on the connected modem and supported technology.

Prerequisites

  • Jetson Orin Nano Super Developer Kit

  • M.2 to USB Adapter

  • LTE/5G Module

  • Monogoto Cellular SIM

Hardware Connection Instructions

Open the Terminal

Connect a monitor, keyboard, and mouse to the NVIDIA Jetson Orin Nano.

After the Ubuntu desktop loads, open the Terminal application from the desktop or application menu.

All commands in the following steps should be executed in this terminal

Identify the Modem Serial Port

Connect to the Modem

Connect the EG25 to Monogoto

Request the product type, hardware and firmware version:

Request the IMSI (International Mobile Subscriber Identity):

Request the ICCID (Integrated Circuit Card ID), which is the identification number of the SIM card

Network Configuration

It is possible to let the modem select the network automatically, or to manually define a network to connect with.

Option 1: Automatic Network Selection

To set the modem to automatic network selection enter the command:

Check the network and cellular technology the modem is currently using:

Expected response: +COPS: 0,0,"<name of operator>",X. The last digit indicates the cellular technology: 0 indicates GSM 2 indicates 3G 7 indicates LTE

Option 2: Manual Network Selection

Start with searching for available networks:

It may take several minutes before the modem responds.

The modem responds with the names and the MCCMNC codes of the available networks. It also shows the cellular technologies the networks support:

To find which of the networks Monogoto has roaming agreements with, review the Coverage lists.

To find the profile of your SIM, visit the Monogoto Console, open the page Things and select a specific Thing. Scroll down to Mobile Identities to find your profile in the column Network Provider Name.

Check the network and cellular technology the modem is currently using:

Expected response: +COPS: 0,0,"<name of operator>",X. The last digit indicates the cellular technology.

Manually set the network and the cellular technology:

Replace XXXXX with the MCCMNC code of your operator, for example"20404" for Vodafone NL. Use 7 for LTE.

Check the radio signal strength and signal quality:

+CSQ returns 2 values separated by a comma. The first value represents the signal strength and provides a value between 0 and 31; higher numbers indicate better signal strength. The second value represents the signal quality indicated by a value between 0 and 7. If AT+CSQ returns 99,99, the signal is undetectable or unknown.

Query Network information

This command returns the Radio Access Technology (RAT), MCCMNC operator code, and LTE band currently in use.

Example response: +QNWINFO: "FDD LTE","20408","LTE BAND 3",1800.

Network Activation

Set the APN to data.mono:

Validate if the APN is set correctly:

Expected response: +CGDCONT: 1,"IP","data.mono","0.0.0.0",0,0,0,0,0,0

Activate the PDP (packet data protocol) context:

Test if the PDP context is activated:

Expected response: +CGACT: 1,1

Validate if your device received an IP address:

Expected response: +CGPADDR: 1,XX.XXX.XX.XXX

Do you see an IP address? Congratulations! You’ve successfully connected the Quectel modem to Monogoto 🎉

Test the connection by sending a PING

A PING test can be performed to test if the modem has an active data connection with a mobile network.

When cellular modems are idle for a long period of time, cell towers might drop the data connection to save resources. Sending regular PINGs is a good method for testing the data connection, as well as for keeping the connection alive because the operator registers your device as being actively used.

Send 3 PINGs to IP address 8.8.8.8:

Example response:
