Wireless data communication method, for communication between a computer peripheral device and a receiver device including transmitting a datastream from a computer peripheral device to a receiver device, with a wireless communication protocol which may operate with a first frequency band and a second frequency band. Each of the bands may be divided into a plurality of sub-bands, which may be further divided into frequency channels. During a first time slot, the operation frequency channel may be a first operation frequency channel selected according to a first frequency hopping sequence from the frequency channels of one sub-band of the first frequency band. During a second time slot, the operation frequency channel may be selected according to a second frequency hopping sequence from the frequency channels of one sub-band of the plurality of sub-bands of the second frequency band. Adjacent frequency channels of any of the frequency hopping sequences may be of different sub-bands. A device implementing the method is also envisaged.

Wireless data communication method, computer peripheral device and receiver device

Disclosed are methods and devices for facilitating the seamless handover of Bluetooth communications of a Bluetooth accessory device from a first Bluetooth host to a second Bluetooth host. A first host identifier uniquely identifies the first Bluetooth host for its Bluetooth communications, and a second host identifier uniquely identifies the second Bluetooth host for its Bluetooth communications. The host identifiers are stored in the Bluetooth accessory device, and they are provided to an application on the mobile device that allows a user to select either the first or the second host as the selected host for the Bluetooth accessory device, without having to re-pair the host device to the accessory device. Because re-pairing is not necessary, the user can quickly and seamlessly switch the Bluetooth accessory's communications among multiple different host devices.

A method, a computer readable medium, and an apparatus for wireless communication are provided. The apparatus may receive, via a radio frequency channel, a first data from a first human interface device at a first time slot of a frame. The apparatus may transmit the first data to a computing device. The apparatus may receive, via the radio frequency channel, a second data from a second human interface device at a second time slot of the frame. The apparatus may transmit the second data to the computing device. The apparatus may transmit, via the radio frequency channel at a third time slot of the frame, at least one of a first acknowledgment to the first data, a first lighting effect configuration data for the first human interface device, a second acknowledgment to the second data, or a second lighting effect configuration data for the second human interface device.
