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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
