Network capabilities in nanoFramework: check!!

As they say: better late than never! This post is a belated announcement of networking capabilities being added to nanoFramework. Some of you may already have noticed that during last week networking capabilities were officially added to our development branch.

With this, nanoFramework has – definitely – reached a major milestone. I’m sure we are all in agreement that providing network connectivity is a must have for any decent framework out there that aims to compete in the IoT space.

A lot has already been accomplished and know that we are just getting started! 🙂
Let me guide you on a tour of what’s available today.

Managed class libraries

The Nuget packages nanoFramework.System.Net, nanoFramework.Networking.Sntp and Windows.Devices.WiFi include already a ton of methods that allow developers to accomplish a lot. Without trying to be exhaustive, one can find there: interface management, DNS services, SNTP service, Sockets, Secure Sockets, Cryptography and Wi-Fi network management (this one for ESP32 targets only).


This is probably one of the paramount features that are requested when embedded developers ask about networking. Yes, we’ve made it 😎 (and we are very proud of it)!
Support for SSL v3.0, TLS 1.0, 1.1 and 1.2 is available right now!

Supported targets

We provide ready to burn images including network support for the following reference targets: ST NUCLEO144 F746ZG, ST STM32F769I DISCOVERY and (of course!) ESP32 DevKit C.

Sample projects

Some work has been done here too. There are available samples showing how to connect to a SSL server; using a client certificate and validating the server certificate; resolve an address by querying a DNS service; adjust the RTC from an SNTP server; scan Wi-Fi networks in range and a couple of others.

Last but, by far, not the least we are working closely with the AMQPNetLite project to add support for nanoFramework and, very soon, an official Nuget package with this library will be published. Feel free to give it a try now, just go ahead and fork our fork.
A PR is also imminent to Paolo Patierno MQTT library. Same goes with this one: feel free to give it a try and do so by forking our fork.


How cool is all this? And we are just getting started!! HTTP client and server, web sockets and others are queued up to add more network capabilities to nanoFramework.

What are you waiting for? Go get all this, connect your device and start coding your next networked project! 😉

  1. Hi, I’m trying to test MQTT from “Samples/samples/MQTT/BasicExample.WiFi/”, on my ESP32_WROOM, but when I debug the program it fails on: client.Connect(clientId);

    error: Excepción no controlada del tipo ‘nanoFramework.M2Mqtt.Exceptions.MqttCommunicationException’ en nanoFramework.M2Mqtt.dll

    Hope you could help me.

    Thank you
