Nordic launches wireless desktop protocol stack

Nordic Semiconductor ASA is offering the Wireless Desktop Protocol, a communications protocol stack for use with the company's 2.4GHz transceivers, such as the nRF24L01TM.

The protocol uses an asynchronous frequency agility transmission scheme offering nominal packet latencies as low as 1.5ms, the company said. It also supports a feature called ReverseBurst, allowing data streaming from the appliance being controlled to the controller.

Support for bidirectional communication means the protocol meets or exceeds the requirements for wireless PC peripherals, Nordic said. The protocol stack also supports star topology networking of up to five control devices with bidirectional data connections to one host, enabling 3-in-1 desktop bundles utilizing mouse, keyboard and remote control.

The protocol stack is designed to run on an 8bit MCU and employs a modular implementation in ANSI-C.

"We have seen an increasing demand for such a solution over recent years," said Geir Langeland, director of sales and marketing at Nordic. "Design engineers do not have time to develop specialist RF expertise when developing in particular consumer electronics products with incredibly short time-to-market cycles."

Nordic did not say how much they are charging for the Wireless Desktop Protocol, or whether it would be provided for free to purchasers of Nordic 2.4GHz transceiver chips.
