Running BLE advertising with device details on CircuitPython

Let’s kick things off by looking back at what we’ve done before, which really sets the tone for this module we used earlier.
The speaker is all about keeping things fresh, so they mention that they’re opening up the old code, erasing it, and getting ready to write something new.
This whole session has a nice rhythmic vibe to it, where we keep talking about starting from scratch, really highlighting that we’re going to dig into the basics.
It’s all about grounding ourselves in those fundamental concepts, so let’s get started!.

Let’s talk about the iDovitizing service, which is pretty much a one-stop shop for information and support to get the most out of your devices.
It’s designed to boost your user experience by giving you all the nitty-gritty insights and helpful tips you need.
Plus, this service is personalized, so it caters specifically to what you’re looking for, making sure you have every little detail and piece of assistance right at your fingertips..

Okay, let’s get started with setting up a Bluetooth Low Energy (BLE) radio for your device information service.
First off, you want to create an instance of the BLE radio, and this is super important because it helps you identify and manage what your device can do.
Next, make sure to configure the BLE radio correctly—give it a cool name like ‘DeviceMart.’ This name is just a fictional example, but it helps illustrate how the device information service is structured and functions.
So, with DeviceMart in place, you’ll have a better grip on how the Divinfo device information service works..

So, let’s talk about the device info service , which is super important for getting the lowdown on devices.
One of the big players here is the manufacturer , the one behind the scenes who actually makes the device.
For instance, imagine a company called DeviceMart producing a bunch of different gadgets, each designed for specific roles.
It’s also worth noting the difference between the manufacturer and the product name; you might see “DMFactory” pop up as a handy abbreviation just to keep things clear..

Let’s talk about software revisions! The current software revision is at version 3.0, which is a big deal because it means there have been some awesome updates and improvements since the last versions.
Now, when we talk about hardware and firmware, they often get their own versions too, and together they create what’s called an integrated version, aka the software revision.
This versioning system is super important – it keeps track of changes, makes sure everything works well together, and rolls out new features and security updates for users.
On the firmware side of things, it’s a little more stable and doesn’t get updated as often, currently sitting at version 2.0, while the hardware version is at 1.5.
Oh, and don’t forget about those unique identifiers like MAC addresses that help to distinguish all these similar-looking devices!.

So, checking your saved device info is super important for making sure everything’s documented correctly before any updates.
When you fire up the light blue app, you get to see your device pop up as DeviceMart with the manufacturer’s name being DNFactory and the model number listed as BLE NRF5840.
Now, let’s talk about MAC addresses—they’re those unique six-byte identifiers for Bluetooth devices.
Sometimes, manufacturers throw in serial numbers as well, and if you click on the serial number, you’ll get a peek at some data formatted in UTF-8, showing something like ABCDEF.
Plus, if you’re curious about software and hardware versions, just tweak that data format to UTF-8 string, and you might find versions like V3.0 for software, v2.0 for firmware, and v1.5 for hardware..

As we wrap things up, it’s exciting to think about what’s coming next! We’re looking forward to diving into a bunch of new and interesting topics the next time around.
This is just the beginning, and it definitely feels like there’s plenty more to explore ahead.
So, get ready for more engaging material and opportunities to join in on the fun in our upcoming videos!.
