Sponsored by Silicon Labs Introduction There’s a groundbreaking new concept emerging in the IoT (Internet of Things) world. We’ve now reached a stage where devices can draw power from their environment, leading to a substantial decrease in energy costs and environmental footprint. This concept, the Ambient IoT, is poised to transform the IoT landscape, and Silicon Labs has just unveiled the xG22E series of chipsets that meet the demand for this new era of devices. Energy harvesting and energy conservation are at the core of the Ambient IoT. IoT devices in this category draw energy from their e ..read more

Sponsored by Silicon Labs Introduction With the rise of smart devices and the Internet of Things (IoT), Bluetooth technology has become an integral part of our daily lives. However, as our reliance on these devices grows, so does the need for secure and reliable connections. Secure pairing/bonding and authentication are crucial elements in the world of Bluetooth Low Energy (LE) devices. Ensuring these two aspects are intact can be a big challenge, primarily due to the need for manual pairing and the lack of a scalable approach to verifying the authenticity of the connections using standard LE ..read more

In this video, we introduce the new NXH3675 Bluetooth LE chipset from NXP Semiconductors, a state-of-the-art chipset that supports the new LE Audio standard. This includes support for both Broadcast/Auracast (up to 2 stereo streams) and Connection-oriented audio (up to 7 CISes or 5 CISes for High Definition Audio).

Debugging Bluetooth LE is tricky, and on mobile devices, it can be even more so! In this guide, I lay out the different steps in detail on how you can debug and sniff Bluetooth LE communication on iOS devices. Specifically, we’ll be capturing the HCI commands and events between the Host and Controller on the iOS device. Host Controller Interface (HCI) Before we dive into the details of how to achieve this, let’s go over a few essential concepts. The Host Controller Interface (HCI) layer is a communication interface defined in the Bluetooth Core Specification document. It standardizes the way t ..read more

Sponsored by Silicon Labs If you’ve wondered whether advertising in Bluetooth Low Energy can be bidirectional, then this post is also for you. If you’ve recently come across the term PAwR and you’ve wondered what it means, then this article is also for you! But first, a bit of background information… Introduction Since the introduction of Bluetooth Low Energy in 2010 (in version 4.0 of the Bluetooth Core Specification), the advertising feature has proven to be a game-changing new topology for the standard. It’s specifically great for broadcasting data in one-to-many applications (e.g., beacons ..read more

Sponsored by Silicon Labs. Introduction Over the years, Bluetooth Low Energy has proven to be great for establishing a connection between two devices and maintaining it within a reasonable RF range. As we already know, connections are the way to go for applications that require consistent bidirectional data communication between two BLE devices. However, connections rely on the two BLE devices being within a reasonable RF range of each other in order to be maintained. But what if you have an application where a BLE medical device must constantly be connected within a large area (e.g., a medica ..read more

Bluetooth Low Energy was designed to considerably reduce power consumption and cost while maintaining communication ranges similar to Bluetooth Classic (50-100m max). However, that is no longer the case. With the new Bluetooth long-range mode, you can now achieve ranges of over 1 kilometer using BLE! This is useful for extending the range of a Bluetooth connection or discovering advertisements, but it also helps achieve more robust communication in noisy RF environments and areas with many obstacles. Now, you may be interested in learning more about long-range mode and implementing it into you ..read more

Introduction In the previous blog article, we covered the iBeacon standard, which is a beacon standard developed by Apple. After Apple released the iBeacon standard back in 2013, Google followed suit with its Eddystone standard in 2015. Unfortunately, both Eddystone and iBeacon have not changed much or improved since their releases. In fact, the Eddystone project repo was even recently archived on GitHub. Nevertheless, they have both remained pretty popular due to the fact that they provide a sort of reference or standard for Bluetooth beacons. iBeacon is also a special case for iOS since it’s ..read more

I’ve received a lot of questions over the years since Bluetooth 5 was released about how the “2x speed” actually works and what to expect in terms of realistic speeds (as opposed to theoretical speeds). So, in this post, I’m going to break it all down for you. We’ll cover: What’s the practical throughput to expect from BLE? Bluetooth 5’s new 2M PHY for data transfer What are the factors that impact/determine data throughput? How do you calculate your application data throughput? How do you maximize your data throughput? Testing, measuring, and calculating data throughput using two ..read more
