Abstract

Existing cordless keyboard and mouse products that utilize proprietary RF interfaces and protocols, are not interoperable, have no security, and have only one-way operation. Bluetooth will bring the wireless keyboard and mouse application into real life by providing standard RF frequency and protocols, having good protection against interference, providing two-way communication, reliable links and secure data transmission. This paper discusses the benefits of wireless keyboard and mouse based on the bluetooth technology and presents how the prototyping of bluetooth wireless keyboard and mouse was done at Motorola Suzhou Design Center, focusing on the system architecture and S/W stacks designed and implemented on the embedded device. All the protocol stacks are designed and implemented above the HCI UART layer on the Motorola 8 bit HC08 micro-controller. Several key issues for prototyping wireless keyboard/mouse such as security and power management are also discussed here.
