Developing an IoT device? Here are five things you should know about CSRmesh™

We recently hosted a live webinar on CSRmesh™ to give developers looking to build Internet of Things devices an introduction to the new solution which allows an almost unlimited number of Bluetooth® Smart enabled devices to be simply networked together and controlled directly from a single smartphone, tablet or PC for the first time.

The session was hosted by Applications Engineer, Alan Hay, who gave an overview of CSRmesh including background, key features, and use cases. The recording can be listened to on-demand here, or you can take a quick read of the five key takeaways below:

1. Bluetooth Smart market growth means CSRmesh can scale quickly

With worldwide annual shipments of Bluetooth Smart ICs set to surge to almost 300 million units in 2018, Bluetooth Smart is now integrated into millions of devices including mobiles, tablets, and laptops. As CSRmesh can be integrated into any CSR Bluetooth Smart device, this significantly increases the scope and scale of available connectivity.

2. CSRmesh allows you to increase the amount of devices controlled by a mobile device

Messages in CSRmesh networks are relayed throughout the network, hopping from node to node, allowing for significantly extended range and extended scope of the use cases. It also offers minimal propagation delay with ~15ms from node to node. Nodes in the CSRmesh network can be addressed individually or assigned to a group, with up to 65,535 devices per network.

All of these devices can be controlled from an application on existing mass market devices. These mobile devices can also be connected to the internet, meaning they can be remotely controlled from anywhere in the world.

3. The network is secure and robust

CSRmesh is based on flood mesh architecture so there is no single point of failure; if one device malfunctions, it doesn’t break the overall system. All messages are encrypted to prevent eavesdropping attacks and authorisation codes are used to prevent man-in-the-middle attacks.

Messages are sent on three separate channels, all of which co-exist very well with Wi-Fi, and are sent using proven CSR silicon including the CSR101x™, CSR8811™, and CSR8670™.

4. It doesn’t require any special hardware

Unlike ZigBee, Z-wave or other proprietary protocols which require an extra dongle or plug-in device, CSRmesh communicates directly from the phone bridging to Bluetooth Smart Ready devices. CSRmesh is also supplied with a software library with accompanying API and is fully compatible with all existing CSR Bluetooth Smart radio devices.

5. The list of use-cases extend well beyond just home automation

Applications for CSRmesh extend beyond just smart lighting to heating controls, temperature sensors, security alarms, access controls and many more. As well as in the Smart Home, mesh networking has an exciting number of uses cases in the enterprise space, for example fitting industrial-scale buildings with smart networks.

Qardio makes health monitoring easy with CSR1010™ Bluetooth® Smart

With connected medical devices one of the most exciting aspects of the growing Internet of Things, we caught up with Qardio, a company in the business of making smart wearable heart health monitors. Rosario Iannella, Chief Technology Officer at Qardio, discusses the benefits CSR’s Bluetooth® Smart technology brings to the company’s latest device, the QardioArm, and his thoughts for how the smart medical devices market will evolve.

CSR: You recently launched the QardioArm blood pressure monitor, which uses the CSR1010™. What’s exciting about the device?

Qardio: QardioArm is a blood pressure monitor with a revolutionary design and effortless user experience that conveniently fits the modern lifestyle. The idea behind the product was to create a medical device that looks like an everyday object and is simple and convenient to have around at all times for daily measurements.

"We looked at different parameters like throughput, power consumption, module design and the completeness of the Bluetooth stack feature set. CSR performed better on every one of these points." - Rosario Iannella, CTO, Qardio

“We looked at different parameters like throughput, power consumption, module design and the completeness of the Bluetooth stack feature set. CSR performed better on every one of these points.” – Rosario Iannella, CTO, Qardio

CSR: When developing the QardioArm what were the top five things you wanted to achieve? 

Qardio: We wanted QardioArm to be easy to use, comfortable, clinically validated with safe data transfer and to have a long battery life. All of this has been possible with the use of CSR’s Bluetooth Smart technology.

The ability to control the device pairing experience directly from the smartphone application has ensured the device is incredibly simple to use from the very first time. A simple tap between the QardioArm and the phone and the user is ready to start using the product.

We wanted the device to be comfortable and the combination of the wireless technology with the compact design created a blood pressure device that is simple and convenient to have around at all times for daily measurements.

The low power consumption offered by CSR’s Bluetooth Smart technology means users don’t have to continually charge their device. And the small form factor of the chip has helped us deliver a compact design.

Users want to feel confident that data is accurate and safely stored. The encryption mechanism embedded in Bluetooth Smart technology has been crucial in helping us achieve that.

CSR: Why did you choose to work with CSR?

Qardio: We looked at different parameters like throughput, power consumption, module design and the completeness of the Bluetooth stack feature set. CSR performed better on every one of these points.

CSR: How do you think the personal medical market will evolve in the next five years?

Qardio: The market has seen an explosion of self-quantified applications in the last few years. Now with medical devices coming to the market with a consumer-focused design we will start collecting an unprecedented amount of clinical data that will help improve patient care. We will see companies creating predictive algorithms giving people the ability to truly achieve preventive care, lowering the unsustainable current trend of increasing healthcare costs.

CSRmesh™ – A key component to the Internet of Things and the world’s most exciting technology, says The Times Raconteur special report

CSR was featured this week in the ‘Internet of Things’ special report, published by the prestigious Raconteur and distributed in The Times. It contains an interesting series of articles looking at how everything is getting plugged into the internet and how through machine-to-machine communications, it is making a sizeable impact on how we live. It’s worth a read, but definitely check out pages 8-9, where CSRmesh is not only mentioned as one of the ten applications making the IoT the world’s most exciting technology, but also because it features a great infographic exploring the segmentation of the IoT market.

“Devices in close proximity relay messages to each other to form a local network. For example, Cambridge Silicon Radio’s CSRmesh uses the Bluetooth radio signal found on every smartphone. The consumer connects to a Bluetooth-smart IoT device, which then sends that message to affiliated devices in a giant chain or mesh. Bluetooth can stretch 30 metres, but via a mesh, a message can leapfrog devices to cover much larger distances.”

Sky News reports on CSRmesh™ and Bluetooth® powering the Internet of Things

CSR recently met with the SWIPE tech team from Sky News to talk about how Bluetooth® is changing the way we interact with the world. Reporting from the Future is Smart exhibition organised by the Bluetooth Special Interest Group, the report focuses on CSRmesh™ having a key role in the future of wireless technology:

“Bluetooth isn’t just about mobile headsets anymore, a new generation of wireless technology is ready to transform homes, exercise, medicine and even farming. It’s because Bluetooth 4.0 lets devices talk to each other using very little power, like these light bulbs from Cambridge-based company CSR. One app can control tens of thousands of [light bulbs] at once, right down to changing the colour of each individual bulb. And the technology has even greater potential.”

Motor Trend highlights aptX® and the importance of compression in audio quality

CSR recently talked with Motor Trend’s Frank Markus ahead of Telematics Detroit 2014. The popular U.S. based publication posted a round-up of the highlights from the show including a section on aptX®, CSR’s audio coding technology which streams CD-like audio quality over a Bluetooth® connection:

“Did you realize that most in-car receivers currently capable of streaming music from your brought-in device are doing so at a lower, MP3-or-worse level of quality? That’s because they use an SBC codec. This low-complexity Sub-Band Coding or (SBC) was specified by the Bluetooth Special Interest Group. British-based CSR plc has developed a different compression coding called aptX that delivers greatly improved frequency response for near-lossless stereo audio quality. PC and Mac computers and Android devices all use aptX today, so the last step is to get the receivers to recognize and employ it for better car-audio sound quality, and that will happen soon.”

You can read the full article here.

The Expanding Role of Bluetooth® in High Quality Audio Applications

I attended Bluetooth World 2014 and was privileged to be invited to speak as part of a panel discussion on the continually expanding role of Bluetooth® in the audio market, what’s driven its growth and the positive impact Bluetooth Smart is expected to have on the sector.Capture

The backdrop to the panel session was a recently published report from Research and Markets which found that the wireless audio market is set to grow 24% through to 2018 and will then be worth $13.75bn. So the panel session was keen to explore what has driven market growth to date and what will continue to ensure the market expands.

Bluetooth for audio first started gaining traction in mono headsets in the early 2000s and was primarily used by busy professionals or safety-conscious drivers to make phone calls. After initial steady growth, the market largely plateaued a couple of years ago until two factors came together to propel a second wave of rapid growth. The first was a dramatic improvement in the audio quality delivered over Bluetooth, and CSR’s aptX® CODEC had a huge part to play there, and the second being the widespread consumer adoption of media-rich smartphones and tablets.

This combination matched perfectly with the consumer’s increasingly mobile lifestyles and resonated with their growing familiarity and use of wireless devices.  As a result, consumers readily embraced listening to wirelessly streamed music either for personal enjoyment, or shared with friends.

Portable Bluetooth speakers were the first music audio devices to really grab the mainstream consumer’s attention, and having gained an appreciation of the capabilities and benefits that Bluetooth audio had to offer, this naturally led to rapid market volume growth. This acceptance and confidence in Bluetooth audio technology then saw the investment in other devices such as headphones and sound bars increase too.

Looking ahead, Bluetooth Smart has the potential to simplify the user experience even further. For example, in Home Entertainment Audio, the technology has the capability to detect who has walked into a room and can automatically queue up a song which relates to previous choices they have made at a similar time of the day. It simplifies the consumer experience, so users don’t have to navigate through menus themselves, making it a much more personable experience.

The wireless audio market continues to grow, and with Bluetooth Smart offering a more tailored experience to consumers there’s no saturation point in sight. But for the true potential of wireless audio to be realised, there needs to be powerful and flexible platforms at the heart of the development. Find out more about how our audio platforms can help deliver captivating audio experiences.

If you weren’t able to attend Bluetooth World, catch up on the panel session – The Expanding Role of Bluetooth in Audio

What do you think will be the future for Bluetooth in audio? It would be great to get your thoughts and any questions you may have on the topic.

CSR accelerates prototyping of Automotive SoC platforms

The design complexity of CSR’s next-generation of platform solutions for Automotive Infotainment creates new challenges that current pre-silicon development methodologies struggle to support.

Together with the Cadence R&D team, CSR’s Technology Development & Implementation (TDI) group took on these challenges and developed a novel solution which enables faster software development during the early phase of hardware design. CSR Israel’s Moshe Berkovich, a senior engineer in the TDI group, presented this new and innovative solution for fast prototyping at the 51st Design Automation Conference (DAC 2014) held recently in San Francisco.

Moshe’s presentation, entitled “Using Palladium/VSP Hybrid to Accelerate SW Development”, was part of the Cadence® Theater at DAC program, a lively place to learn – directly from EDA users – how to apply Cadence tools to real-world problems.

The new concept offers a hybrid solution which blends the real hardware implementation with the virtual/abstract modules of the compute-intensive CPU. Together, CSR and Cadence have demonstrated a new approach to accelerated simulation environments which is claimed to be 200 times faster than existing solutions.
