FOMO to Flow: Building Gen AI Solutions

Unlock the power of Generative AI by learning to interact with large language models programmatically—and take it further with fine-tuning for customized responses. If you’re a software maker feeling the fear of missing out (FOMO) on the Gen AI revolution, you’re not alone. The way we build and interact with software is evolving rapidly. “Google it” or “check Stack Overflow” is no longer the go-to approach — AI-first, conversational tools are becoming the new standard across development, design, and decision-making.

DNS Resolution In Thread Network

In previous articles, we explored communication between a Thread device and external (non-Thread) networks, primarily over TCP/HTTP using IP addresses and ports. However, in real-world applications, we rarely use raw IP addresses. Instead, we rely on hostnames — which are resolved to IP addresses using DNS (Domain Name System). Public DNS resolution (like Google’s 8.8.8.8) handles global domain names, typically configured at the OS or browser level. But for private, local networks — like those used in IoT and Thread-based deployments — we need a local DNS setup to resolve custom hostnames (e.

OpenThread Commissioner Implementation in Java

In a previous article, we explored how to build and use an Android app as an external commissioner to onboard Thread devices into a network. This article takes it a step further by demonstrating how to implement a Java-based external commissioner. The thread commissioning process involves the following key steps: Discovering the Border Router Connecting to the Border Router Adding Joiner Rules Joining the Thread Network In this guide, we will implement these steps in a Java application, providing a clear and structured approach to external commissioning in OpenThread.

Building and Using OpenThread Commissioner Mobile App

In our previous article, we set up an external commissioner outside a Thread network using a command-line tool on a PC. However, OpenThread also provides a mobile app that can serve as an external commissioner. This guide will walk you through building and using the OpenThread Commissioner mobile app to provision a device onto a Thread network. Building the OpenThread Commissioner Mobile App OpenThread provides an Android app source, which requires Android Studio and Android NDK to build.

External Commissioning in Thread Network

In our previous article, we set up a commissioner within a Thread network by starting the commissioner from a thread node. However, a Thread network can also be provisioned using an external commissioner outside the thread network. This article will guide you through the configuration of an external commissioner for a Thread network using a Commissioner CLI setup on a mac/linux pc. Commissioner CLI The Commissioner CLI can be built on macOS or Linux using the following steps:

Implementing a TCP Client in nRF Connect

In a previous article, we implemented a Joiner that is programmatically provisioned by a Commissioner node to join a Thread network. Once an IoT device is part of the Thread network, the next step is to enable communication with other Thread nodes or external hosts. We previously discussed and tested UDP-based communication in Connecting Thread devices to Internet. In this article, we explore a similar approach with TCP OT CLI, and here we are implementing a custom TCP client that sends data to a TCP server programmatically.

nRF Connect SDK Advanced Practices

In our previous article, we provided a brief overview of the nRF Connect SDK and demonstrated how to build a simple application. This article explores advanced practices for working with the nRF Connect SDK, focusing on Zephyr OS internals, including timers, schedulers, bootloading, DFU, and FOTA concepts. It builds on our previous introduction to the nRF Connect SDK and provides insights into developing multi-threaded firmware, troubleshooting, and deploying firmware over the air (OTA).

Implementing a Joiner in nRF Connect SDK

In a previous article, we explored how a Commissioner node provisions a Joiner in a Thread network using OpenThread’s default firmware. However, in real-world applications, custom firmware logic is often required, along with programmatic control over the commissioning process. In this article, we will implement a Joiner using the nRF Connect SDK, following these four key steps. Joiner in Action The Joiner process involves the following steps: Enable Thread – Ensure that the Thread network and IPv6 are enabled.

Simplifying Thread Network Provisioning with Joiner and Commissioner

In previous articles, we explored the Thread protocol and connected Thread devices to the internet using a Border Router. We joined the Thread network by manually configuring each node with a full dataset containing network credentials such as the PAN ID, Network Key, Network Name, and more (refer to Step 6.1: Access Network Credentials). While this method works, it becomes impractical when provisioning hundreds of Thread devices in real-world scenarios.
