Giveaway Week 2025 – RAKwireless Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit

It turns out we don’t have two, but three companies offering free samples on CNX Software this year. The last one is a regular, and RAKwireless joins us for the fifth year running with a Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit that can be useful for industrial automation and asset-tracking applications. Regular readers may recall that it is the same prize as last year. While I usually prefer getting a new devkit, the company didn’t launch any this year (just some Meshtastic kits). The good news is that if you missed out last time around, you have a chance to give it another go. Here’s what the winner will get as a reminder: RAK4631 WisBlock Core Module based on Nordic Semi nRF52840 Arm Cortex-M4F microcontroller @ 64 MHz with 1 MB Flash, 256 KB RAM, Bluetooth Low Energy 5.0 protocol stack Semtech SX1262 LoRa Transceiver with LoRaWAN 1.0.2 protocol stack […]

The Future of Asset Tracking: IoT at Scale with LTE-M technology

CNXSoft: This is a guest post by Ohad Peled, Product Marketing Manager at Sony Semiconductor Israel, about the challenges of tracking a large number of IoT assets and how LTE-M can help businesses scale tracking solutions. Over the last few years, asset tracking has emerged as a critical business function and is estimated to grow to a $34.5B market by 2032, according to Custom Market Insights. Whether businesses are monitoring a global supply chain or keeping tabs on expensive equipment, knowing where assets are at all times is essential. It enables businesses to optimize supply chains, prevent theft, and reduce operational downtime. There are several technical and commercial challenges in deploying such a solution, which could result in failure to deliver the promised value. Some solutions struggle to maintain accurate tracking as assets move within or across different facilities, especially if they go through an indoor environment. Others suffer from […]
