| Well, Co-founder of Makerdiary is here :) I love this article, and I wanna promote our works in this thread :) We are build some little Nordic nRF52-based widgets for maker with a lot of documents, you can find more wiki at here[1][2]. And we are try to use MESH network technology to protect our IoT data, here is some tutorial for BLE MESH[3] and OpenThread MESH[4]. BTW, if you are intersted in FIDO U2F security key, please check here[5], an open source FIDO U2F implementation on nRF52 SoC.
