Five Steps to Get Your Bluetooth® Smart Product to Market

Now that our low-cost Starter Development Kit is now available globally via Broadband, BCD MicroelectronicsDigikey and local CSR distributors, developers all over the world are able to begin designing new fully-featured Bluetooth® Smart products that take the technology in exciting new directions. Whether these are used for known applications such as wearable heart rate sensors, or for entirely unheard of ones, CSR is dedicated to easing developers’ efforts in bringing these ideas to market as simply as possible. The Bluetooth Smart development process can be daunting for those just starting out, which is why I have put together some pointers to help get developers new to Bluetooth, started.

For more detailed support, don’t hesitate to check our newly launched wiki or send us questions via our new developer forum.

1. Design Prototype Hardware


2. Develop Prototype Software

  • Application and software development is enabled by the CSR µEnergy®  Software Development Kit (SDK), included within the Starter Devolpment Kit. The integrated development environment is built upon xIDE, and so has a similar look and feel to the SDKs and ADKs that are offered for many other CSR Bluetooth devices
  • In order to use Bluetooth Low Energy technology, a device must be compatible with the GATT Bluetooth profile and define a set of appropriate services
  • The SDK includes example applications for popular Bluetooth Smart profiles that can be run on the target board such as heart rate sensors, alert tags, mice and keyboards, cadence sensors and many more. The next step is to create the Target Software based on a CSR example application for a chosen profile or define your own services for a custom profile
  • Either extend an example application with functionality needed for specific product or define a new application, typically starting from one of the example apps
  • Create smartphone app based on CSR µEnergy app framework. Example CSR apps for Android can be downloaded from Google Play and they include CSR Android Heart Rate App, CSR Android Cycle Speed App and the CSR Running Speed App. Developers can also download the CSR iOS app from the Apple App Store which includes example code for Blood Pressure Meters, Glucose Meters and Health Thermometers


3. Build Pre-Production Hardware

  • Combine Reference Module design with application-specific hardware in pre-production PCB
    • Based on CSR Reference Module manufacturing pack
  • Manufacture pre-production PCBs


4. Integrate and test hardware and software

  • Build a production test environment based on CSR Production Test Tools
    • Programme unique Bluetooth address
    • Trim the XTAL
    • Load target application to non-volatile memory
    • Test the Bluetooth radio functionality using direct test
  • Test overall product functionality


5. Move to Mass Production

  • Obtain regulatory approval dependent on region and product type
    • Simplify CE and FCC approvals by using CSR pre-qualified radio design from Reference Module
  • List End Product on Bluetooth website
    • Simplify SIG listing by association with CSR QD ID (B017702) for reference module
  • Publish smartphone app to Android and iOS markets
  • Ramp volume production
  • Implement marketing and sales activities

Bluetooth® Smart jewellery fuses fashion and function

CES starts tomorrow and wearable tech is set to be one of the hot trends at the show. But what do consumers want when it comes to wearable technology? CSR decided to ask them and found that 72% say that it’s important that wearable technology devices look good and 67% feel it’s important that they fit with their personal style[1].

So we decided to develop a range of connected jewellery, powered by our latest Bluetooth® Smart solution, to demonstrate the future of wearable technology. The pendant-style connected necklaces contain integrated electronics that enable the wearer to customise the colour and brightness emitted to suit their mood, or to coordinate with a particular outfit.

The electronics integrated into the jewellery have been designed to support a range of functions and so they can also alert users to new notifications on their smartphones, an application that would be suited to a connected bracelet, for example.

The jewellery uses the CSR1012™, part of the proven CSR µEnergy® range, which has been engineered specifically for the wearable technology market. It allows the pendants to connect to smartphones using a fraction of the power of standard Bluetooth by connecting directly to a small lithium battery. It’s also designed to enable a small form factor, making it ideal for wearable accessories.

We can’t wait to see what other truly wearable devices developers come up with. If you’re a developer thinking about developing a Bluetooth Smart powered wearable device and need some advice we’d love to hear from you.

Bayan Audio launches beautifully designed portable speaker with aptX®

Last week saw the launch of Bayan Audio’s latest Bluetooth® wireless speakers – the new Soundbook X3. The latest addition to the Soundbook range, it comes complete with aptX® technology. Combining unparalleled design, aptX and Bluetooth v4.0, Bayan Audio has created a product that is portable yet powerful enough to fill a room with rich sound.

CSR has worked with Bayan Audio previously on its Streamport products and the original Soundbook to create wireless products that are beautifully designed, with aptX providing near CD-quality audio over the Bluetooth connection.Soundbook X3

Bluetooth 4.0 is also included to allow maximum connectivity and is compatible with version v2.1 and above. Integrated NFC technology ensures a fast, hassle-free way to pair with compatible devices – requiring only a single touch to connect and get started. TDMA noise rejection ensures clear, uninterrupted listening whilst the built-in battery provides 10 hours play on a single charge.

With increasing consumer expectations in wireless audio, high quality stereo audio over Bluetooth has become a must-have feature in such devices, so we wanted to ensure that the Soundbook X3 produced incredible wireless audio quality. aptX delivers on that front.

The engineers at Bayan Audio carried out back-to-back tests in their sound lab to prove to themselves the benefits of aptX: subjectively better stereo separation, more defined soundstage, depth, detail and demonstrably measureable improvements in frequency response and dynamic range, which benefits from the 20W combined power and quad 1.5” speaker drivers, with 3.25” passive bass radiator.

Initial reviews have already started coming in praising the Soundbook X3’s audio quality and the ease of Bluetooth pairing. We believe that aptX coding technology, with its impressive dynamic range, has made a big contribution to enhancing the audio experience the X3 delivers.
