Need help developing your IoT prototype with CSRmesh™?

Earlier this month we launched the CSRmesh™ Development Kit to offer developers the opportunity to get hands on with the CSRmesh  Bluetooth® Smart protocol. Designed to accelerate prototype development of new low power connected Internet of Things (IoT) products, the kit includes development boards, a USB programmer and access to the development platform (SDK) which guides you through to example IoT applications. Kits are available from CSR distributors and are initially offered with software supporting networked lighting applications, with updates for home automation and other IoT applications based on CSRmesh due later in the year.

In this introductory video, CSR senior applications engineer Alan Hay takes you through a step-by-step guide on getting started with the kit, explaining what’s included and how to download the necessary software. Check the below video to watch and get unboxing!

If you want to find out more about CSRmesh visit http://csr.com/products/technology/csrmesh or for a more in-depth explanation our latest webinar ‘An Introduction to CSRmesh’ is also now available on demand.  Our forum and wiki are also great resources if you are developing with CSRmesh.

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.”

4. How Radios Work: Building blocks: modulator and demodulator

This post continues to look at the building blocks of radio systems. The frequency reference and the synthesizer were covered last time, so if you’re still here :-) this post will look at how the information to be transmitted is created and added – this is an extension of the transmit and receive information from post 1.

2. How Radios Work: Basic and key concepts – part B

The last post looked at the basic elements that make up radio communications, so now let’s tackle how some of this can be represented graphically. And just to recap: key concepts are written in bold italic and terms that you’ll often encounter in technical documents are in italic.

1. How radios work: Basic and key concepts – part A

This series of articles aims to give a gentle introduction to radio communication. Radio frequency (RF) technology is fundamental in CSR’s business and with these posts the aim is to try and demystify what can often be seen by non-specialists as something of an arcane art.
