In any BLE application, there are (at least) two devices involved: a BLE Peripheral device and a BLE Central device. Usually, the BLE Central is a smartphone, but that doesn't mean it has to be! What if: you do not want to have to launch an app everytime you want to control a BLE Peripheral? you want to have a dedicated device that acts as the remote control for the Peripheral device? you want to utilize Bluetooth 5 features such as the long-range feature (Coded PHY)? (which currently does not exist in any smartphone) you want to learn more about how a [...]

Let's face it... One of the hardest things when working with BLE is simply getting started. Whether it’s the setup of the IDE, the configuration of the project, or the implementation the BLE application. I've been there... I've felt lost, not knowing where and how to start... This is especially true since I was trying to learn the technology itself (BLE) in addition to learning an SDK, platform, and IDE all at once! It just felt overwhelming and way too many things to learn at one time. Lately, I've been focusing on one platform/chipset: Nordic's nRF52. This is due to [...]

You’ve probably heard so much about the recently released Bluetooth 5. You’ve seen all the hype on 2x Speed, 4x Range, and 8x Advertising data increase capabilities. But what does this all mean?? How does it achieve all these improvements? Is it really possible to achieve all these simultaneously?? What about power consumption? How is that affected? Look: There was so much media hype surrounding the release of Bluetooth 5, and lots of conflicting information with very few details. Many media articles made it sound like you can achieve all these simultaneously! In this first post of a series on [...]
