PicoLTE Hello World: Test Your Setup in One Command

Introduction

Before diving into your own application development, it’s important to make sure your PicoLTE or PicoLTE 2 setup is ready to go. This quick-start script helps you do exactly that. With just one command, you can check if:

The device powered and responsive
The SIM card detected and ready
The network registration is successful
Internet access is live

Running this check isn’t mandatory — but it’s highly recommended. It’s the easiest way to make sure everything is set up and ready, saving you time and avoiding surprises later.

Think of it as a preflight checklist: run it once, confirm all systems are go, and move forward with confidence.

Script Location

You can find the script inside the SDK under:

examples/__basic__/monitor_network.py

How to Run

Upload the script (or the full examples/basic folder) to the root (/) directory of your PicoLTE device using Thonny.
Open the script in Thonny and simply click Run.

Is Everything Ready? Here’s What the Script Confirms

This script acts like a pre-flight checklist for your Pico LTE. Before you move on to building your main application, it quickly confirms that your hardware, SIM, network connection, and internet access are all working as expected — so you can start with confidence. Here is a summary of what's covered and why it’s important:

Check Area	What It Does	Why It Matters
Device Info	Confirms module identity (Quectel BG95), IMEI, firmware, manufacturer, model	Ensures the hardware is alive, properly connected i.e Pico can communicate with LTE module.
SIM Card Info	Checks ICCID (SIM serial) and ready status	Confirms the SIM card is present, readable, and ready to use
Network Type	Reads current configuration for RAT scan mode.	Shows RAT will be scanned by the device.
Signal Quality	Measures RSSI (signal strength) and bit error rate (BER)	Helps identify if weak or no signal could affect performance
Network Status	Reports operator info, LTE registration, serving cell, extended signal stats, connection status	Confirms the device is properly registered and communicating with the network
Packet Service & APN	Retrieves APN setup, IP address, and packet attach status	Ensures mobile data is properly configured and attached
Connectivity (Ping)	Pings external servers (like Google) to verify end-to-end internet access	Validates full-path connectivity, ensuring the device can transmit data successfully
