Introducing the latest Bluetooth low energy solutions from Cypress, the BLE Pioneer Kit, CY8CKIT-042-BLE.
In this Video, we will cover the various aspects of the development platform, including the hardware kits, the software tools, and some of the example projects.
So this kit includes the following, the first have the BLE Pioneer base board, it’s got the Arduino shield form factor, a USB and it also has a CapSense slider, an RGB LED, a couple of switch buttons and on the rear side of the kit, you have this 3.3 volt coin cell battery holder.
In addition to the baseboard, you have these two modules that plug into the board, one for PSoC4 BLE and another for PRoC BLE. These modules are fully self-contain systems.
The module simply plugs into the kit in this header, you are now ready to evaluate and develop with PSoC4 BLE. Also included in the kit is 3.3 volt coin cell battery, a USB cable and some jumper wires.
And lastly, you have this Quick Start Guide that has more information on the various pieces of the kit and also shows you how to get started.
Now let’s take a look at the kit in action, to get started, I’ll use the coin battery and plug it into the rear of the kit, and I will demonstrate this with the CYSmart mobile application for IOs devices on my ipod. To put the kit into Bluetooth advertising mode, you simply press this button, which turns the red LED on into a blinking state; I then open the CYSmart mobile app, and start scanning for devices around me. I can touch on this to connect to the device, and then see a carousel of the profile or characteristics running inside this device. I’ll start the demonstration with the CapSense button, and if I move my finger along the CapSense slider, you’ll notice that the information being relayed to the phone over the Bluetooth low energy link.
Also running in this demonstration, is a more digital design with LED color mixing, clicking on this shows me a color gamut with an intensity slider, which I can turn up all the way and then pick a color I want to display on the RGB LED, I can change the color to red or anything else that I would like.
Lastly you can also look at the raw data in the Gatt DB and it shows both the CapSense and the RGB LED slider. Cypress also provides the CYSmart mobile application for android devices.
Now let’s take a look at CYSmart for Windows, and to do that I’ll plugin the USB dongle into my computer, I will then open the CYSmart windows utility and put the kit into its advertising mode again.
I press the start scan button to look for advertising Bluetooth devices around me, and you’ll notice the CapSense LED and slider shows up here. I can click on it and connect to it, I can also click the Discover All Attributes button to see all the services that this device is exposing, and as you can see here you are presented with list of all the services and characteristics running on this project. You can hit the Enable All Notifications button, and I’m moving my CapSense Slider on the kit, and you can see the raw information being relayed in the CYSmart application.
Now let’s take a look at how this project is implemented in PSoC Creator. Under the Example and Kits menu, I can scroll down and look at the example projects that I included with the BLE pioneer kit, the particular example project that I just showed you is the PSoC 4 BLE CapSense Slider and LED demo, so let’s open that up and take a look at how it was implemented.
Walking through the schematic of this project, before us we have a CapSense component here, let’s configure it to operate the CapSense slider, we also have a pin component here which allows the user to press the button to wake up the system from sleep and also put it into an advertising mode. You’ve got a couple of PriSM components here that allow us to do the color mixing and driving of the LEDs, and most importantly the Bluetooth Smart component that is configured with a custom profile to showcase the CapSense slider demo and the RGB LED.
Let’s open the Heart Rate Sensor project for a quick demo, each of these projects also includes a detailed datasheet which talks through the specifics of how it was implemented.
What’s nice about the BLE component is that it provides you a graphical user interface to configure your entire Bluetooth low energy protocol stack.
You can also use several of the other analog and digital components on the PSoC device to implement your sensor interfaces or your controlling communications.
So that was the quick introduction to the new BLE pioneer kit from Cypress Semiconductor.
