Abstract:
1. A communication protocol for use in a wireless network, the wireless network having a transceiver and a plurality of wireless input devices, at least one wireless input device configured as a unidirectional device and at least one other wireless input device configured as a bidirectional device, the communication protocol comprising: a unidirectional mode for communication from the unidirectional device to the transceiver; and a bidirectional mode for communication between the bidirectional device and the transceiver, the communication being either bidirectional or unidirectional, wherein a size of reports transmitted by the bidirectional device to the transceiver is negotiated between the bidirectional device and the transceiver, the negotiation comprising: receiving, by the transceiver from the bidirectional device, a size adjustment request with a requested size, responsive to the transceiver accepting the request, the transceiver setting a report receipt length from a prior size to the requested size and indicating acceptance of the request by transmitting to the bidirectional device, a first report at the requested size, and responsive to the transceiver not receiving a second report at the requested size from the bidirectional device within a timeout period, the transceiver setting the report receipt length to the prior size.
