Playing with Mesh Networking on the Nordic nRF52840 @NordicTweets @electronutLabs
Over at Electronut Labs, they are looking at Thread and MQTT-SN mesh networking with the Nordic Semiconductor nRF52840 chip. They write:
This article is about one such technology – Thread – an IPv6 based mesh networking technology aimed at home automation and similar IoT applications. Specifically, I will be talking about OpenThread, which is an Open Source implementation of the Thread protocol. More specifically, I will be talking about running Thread on the Nordic nRF52840 SoC which supports both BLE and 802.15.4.
I won’t go into to explaining Thread here – the OpenThread website has a wonderful Thread primer that you should read to get started. The Thread group also has a list of whitepapers which you will find useful. Ultimately you should probably read the Thread specification itself, a 348 page password-protected, watermarked PDF which the Thread Group will send you – after you fill up their form and agree to their EULA. It ain’t exactly light reading.
The objective: Build a Thread network using Nordic nRF52840, and establish bidirectional communication with a Thread node via the Internet from any computer.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
