We recently announced that we now support “extended industrial temperature range” (-40 – 105C) on our nRF51822. The devices supporting -40 - 105C are the QFAA (QFN with 256kB flash and 16kB RAM) and the…

Introduction Using proprietary protocols can be an effective way of addressing shortcomings in BLE. When communicating between two nRF chips, one can for example use a different packet format or different…

Hello everybody, I have just published the sourcecode of FruityMesh on GitHub. It is a meshing algorithm that uses standard BLE connections. Plug in as many nodes as you like and they will automatically…

One of the samples available in the nRF Connect SDK is the Secure Partition Manager, which is required to run applications in the nonsecure domain of the CPU. The sample uses the SPM library available in…

Scope The goal of this tutorial is to set-up your own custom Bluetooth Low Energy service on an nRF5340 acting in a peripheral role. We will set up a new Bluetooth LE project from scratch. The finished…

Purpose When creating a mesh network with many nodes, it can take a while to provision each node, especially using PyACI.  An alternative is to use a static provisioner that provisions the nodes automatically…

The MQ Telemetry Transport (MQTT) protocol is hugely popular in IoT because it is lightweight and versatile. In this post we will enable Transport Layer Security (TLS) in the mqtt_simple sample from the…

What is the difference between SDK and Softdevice? How can we select SDK and Softdevice versions? Do the SoC, SDK, and Softdevice have version compatibility problems? How can we understand the SDK directory…

I have spent a bit of time recently experimenting with different TLS credential configurations using nRF91-DKs. Eventually I got to the point where I wanted to do things like swap out the certificates…
