The critical need for contact tracing as part of the battle to fight the COVID-19 pandemic has accelerated the IoT revolution by helping to break down opposition to why, how and where personal data is used.

Bluetooth Mesh lays a framework for large-scale industrial deployments using technology that is already secure, reliable, and supported by all smartphones.

A device with two user-accessible processor cores may seem a bit excessive, but when you understand why Nordic has spent millions of R&D dollars bringing nRF5340 to market, you’ll see it’s anything but.

By simplifying design and certification, low power cellular IoT applications can move from concept to deployment in just a few weeks.

Sophisticated technology is now on hand to track goods in transit, not only instruct where a parcel is on its journey but also to log and report what conditions and events it has been subjected to.

Dig below the hype and you’ll discover there are real benefits to mesh networking.

Battery life is one of the most important considerations when designing wireless products. If it is too short, users will have to charge or change batteries often, leading to frustration and possibly less use of the product. But as well as making sure your battery has enough capacity, you need to make sure your product is using it effectively.

Talking about power consumption can be like running into a minefield of misconception, prejudice and marketing buzzwords. Determining what all the statements mean in reality is not always an easy task. 

Before evaluating the various connectivity options for your IoT project, it’s important to understand the functional architecture of IoT solutions.

When designing your product, it’s crucial that you choose a memory technology that lets you update your firmware easily. Otherwise, you may have to scrap a lot of products if you find errors. If this happens after they've been shipped to end customers, the negative impacts will be severe.

Firmware is held in non-volatile memory such as ROM, EPROM or flash memory. Let’s take a closer look at one of them: flash memory, which enables device firmware updates (DFU) and the advantages that this gives.
