Nordic nRF52840 QR Code based Thread Network Commissioning @electronutLabs @NordicTweets
Our friends at Electronut Labs continue their work with the Nordic nRF52840, using QR codes to pass network credentials to the device via a Raspberry Pi camera instead of hardcoding or typing in passwords.
They show how to generate the QR code and then reading the code via a Raspberry Pi and attached camera. Then they demonstrate a Python program to use the information for network commissioning. They write:
…that’s how you can use a camera on the Raspberry Pi Border Router to commission your Thread device. Although this method may look like external commissioning, since we’re actually using a separate program to parse the information and run wpanctl to manually add the joiner, this looks more like a variation of on-mesh commissioning to me. Who knows? Maybe the Thread experts will tell us. In any case, it works.
