Continental awards CSR for “zero defects” quality

Continental quality awardGil MacInnes, VP Quality, CSR reports on Continental’s recent quality award for CSR’s outstanding performance…

Automotive electronic systems OEMs such as Continental, one of our biggest customers, are extremely demanding when it comes to quality control. So CSR puts its Automotive Infotainment products through additional exhaustive testing before production release to customers.

Automotive customers demand that each and every product functions properly over the entire operational temperature range. They also put in place special project milestones (“quality gates”) to check this whenever they commence a production run and sample over time.

Every device that fails this testing phase is returned to CSR under RMA (“return merchandise authorisation”) for analysis of the root cause of failure and determination of corrective actions. So CSR doesn’t want any failures…

As testament to CSR’s total quality systems, the company recently received a “Best Supplier 2013 Award” from Continental’s Tianjin factory in China, the biggest Continental site we supply. So a big “well done” to the team in Cambridge and San Jose for ensuring the high quality of product and service.

CSR ships multiple Bluetooth® products – and the 3eLPa, a SiRFstar GPS product – to Continental’s Tianjin factory; in 2013 we shipped 1.4 million parts to them with zero failures in their line and at their end-customer.

Continental Automotive Systems (Tianjin) Co., Ltd., incorporated in January, 2007, is a wholly foreign invested enterprise affiliate to the Automotive Systems Division of Continental AG, German. It is located in Central Industrial Zone of Tianjin Economic & Technological Development Area (TEDA), and has around 560 employees. The company is mainly engaged in the production of automotive electronic products such as electronic control system, sensor system, body electronic products and intelligent on-board communications system and serves for auto makers and their suppliers and customers in the world, including many famous auto makers in North America, Europe, and Asia markets.

DirectOffice® – test chart showcases output quality

CSR’s DirectOffice® enables high-quality direct printing of Microsoft Office documents without a PC, Microsoft Office or even a print driver. DirectOffice is the only solution of its kind that can closely match the output of Microsoft Office.

To showcase the superior output fidelity of DirectOffice, CSR has created a test chart that exercises many different fonts and Microsoft Office elements on a single complex page.

The output from this test chart shows how well DirectOffice stacks up against Microsoft Office:

We encourage customers to download the original Microsoft Word (.docx) version of the test chart and try it on any other Microsoft Office rendering solution.

And we’d love to hear about your results: please e-mail CSR’s Philip Mazzilli or simply comment below.

Thank you.

Bluetooth® Smart comes of age for Internet of Things applications

At Embedded World this week we are excited to launch our new Bluetooth® Smart solution, CSR Mesh. By allowing for an unlimited number of Bluetooth Smart enabled devices to be simply networked together and controlled directly from a single smartphone, tablet or PC, CSR Mesh is opening up a new era of possibilities when it comes to the Internet of Things. We think it’s a real game changer for the market and will make Bluetooth Smart the technology of choice for smart home applications.

Unlike other home automation connectivity solutions available, CSR Mesh allows consumers to directly control devices and collect sensor data from a mobile device anywhere in the home. CSR Mesh uses a light weight protocol that minimises the power consumption in each device within the mesh. CSR Mesh is easy to set up, and devices can be configured from a smartphone or tablet to be controlled in groups. Switches and displays can also be added as standalone devices, just attached to the wall with no wiring. The CSR Mesh solution runs on CSR Bluetooth Low Energy single mode devices, and is built above and compatible with the Bluetooth 4.1 specification.

CSR is supporting a number of lead customers with the CSR Mesh technology and will be launching a development kit to a wider audience in the coming months. We’re looking forward to seeing how this solution kick starts the smart home market. But, it’s not just transforming homes. In the CSR Mesh video, the team gives us their take on what the possibilities hold for the technology and how it will enable the future of the Internet of Things.

We’ll be showing our CSR Mesh lighting demo at Embedded World in Nüremberg Germany from 25 – 27 February, where we will also be showcasing how CSR’s Bluetooth Smart Starter Dev Kit can help you create fully-featured Bluetooth Smart devices, such as heart rate monitors or cycle speed devices. Come and see us at Hall 4A, stand 4A-519. We look forward to seeing you there.

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
