NORDIC NRF52840 QR CODE BASED THREAD COMMISSIONING Nordic nRF52840 QR Code based Thread Commissioning 15 Aug 2018 Introduction. I recently wrote about using Thread and MQTT-SN on the Nordic nRF52840 multiprotocol SoC. One thing I did not cover in detail is Thread Commisioning - a secure process by which a device joins a Thread network. I side-stepped the process by passing the network credentials directly to the device using the ELECTRONUT · PROGRAMMING & EMBEDDED SYSTEMS Vibration Analysis with Blip nRF52840. In the midst of launching our crowd supply campaign for nRF52840 based board Blip, we decided to do a project with it which will show some of its capabilities. Blip is a development board for Bluetooth Low Energy (BLE) and 802.15.4 based wireless applications, based on the Nordic Semiconductor nRF52840.

I just got the batch of ATtiny85s I ordered for some pals at a local Maker group. I have articles here on ATtiny84, but not on this chip.So here are some quick notes on getting started with the ATtiny85. PLAYING WITH THREAD AND MQTT-SN ON NORDIC NRF52840 Testing. To test our Thread device, turn the DK on and wait for LED1 to stabilise. Then, press Button 2, which will start looking for an MQTT-SN gateway. When a valid gateway is found, LED 3 will light up. Now press Button 3, and our device will connect to the gateway. Upon successful connection, LED 4 will light up.
