Reference design packages design of Bluetooth Smart remotes

December 23, 2015 // By Graham Prophet
Developing advanced Bluetooth Smart remote controls has, says Nordic Semiconductor, been simplified to 'check-box-clicking' with its 'nRFready Smart Remote 3' reference design; which comprises a complete hardware and software Bluetooth Smart reference design featuring voice input control, 39 programmable buttons, 6-axis motion sensing, and multi-touch trackpad

Targeting remote control OEMs/ODMs and smart TV, set-top box, and digital media device manufacturers, the nRFready Smart Remote 3 reference design is designed to deliver an intuitive and engaging end-user experience. It employs voice input and speech recognition control, a 6-axis motion sensing 'Air-mouse', multi-touch trackpad technology, plus 39 developer-programmable buttons and legacy IR hardware support (to control IR-only products).

"One area we have worked hard to really further optimize is the voice input control," explains Nordic Semiconductor Product Marketing Manager, John Leonard. "This includes developing an even more robust wireless link for wireless audio data, and 20% better current consumption compared to Nordic's previous nRFready Smart Remote 2 solution."

Leonard claims that developing advanced Bluetooth Smart remotes using the nRFready Smart Remote 3 reference design has been made "check-box-clicking" easy thanks to a newly-developed configuration Wizard that works in the Keil development environment.

"The Wizard and underlying software is built in a modular format that has refined the developer element down to a list of check-boxes that allow every parameter of the remote to be configured and fine-tuned," explains Leonard. "This includes large chunk function decisions such as whether to employ a track-pad or motion sensing, down to specifying the number of milliseconds it takes for the remote to wake-up from sleep mode."

In operation, the nRFready Smart Remote 3 reference design employs Nordic's nRF51822 System-on-Chip (SoC) and so is designed to work as an add-on for Nordic's existing nRF51 Development Kit (DK). An nRF51 DK is required to use this reference design but is not included and must be purchased separately. The add-on contains all the external sensor devices that can interface with the nRF51 DK.

 

Additionally, there is a complete product example remote control included in the kit which can be used directly for evaluation, testing, and demonstration. All necessary firmware and host software (including support for Linux) is provided to implement a full design at
