Custom BLE Services with the nRF SDK

It’s very hard to write an introduction to an article about BLE without sounding a little ridiculous. What are you going to say, that it’s all around us today? It’s been all around us for five years. It’s the #1 choice for IoT applications today, owing in no small part to the fact that you can connect to any IoT device with a phone.

Today, I’m going to “talk” you through one of the most common, but also one of the most illustrative tasks that BLE development involves: writing a custom service (or a “vendor-specific service”, in BLE jargon). We’re going to do it from scratch, and we’ll discuss all the background on why we do things as we do — a lengthy discussion but, I hope, a useful one.
